If you’ve just pulled out your puffer jacket, it’ll soon be time to put it away again.

The Bureau of Meteorology is forecasting a steady climb from Tuesday’s high of 16 degrees (when we say high, we’re being generous given there was morning frost!)

Senior climatologist Felicity Gamble says a blocking high in the Tasman Sea is growing stronger, which will soon bring warmer conditions to the capital.

She said that, combined with a few inland troughs, it means warm air from inland and northern Australia will be pulled over to the country’s southeast.

“Often you get a spike in temperatures just ahead of that front … If it has quite a significant cool air mass behind it, which we have seen in the last few days, that cold air mass can encroach very quickly.

“You see a sudden shift from the northerly airstream and getting very warm temperatures to suddenly having that very cold air mass that comes in behind the cold front.”

The temperature will remain in the low to mid-20s until Friday, then rise to 28 to 30 degrees over the weekend.

On the coast, Batemans Bay and Moruya will reach the high 20s, while Queanbeyan will hit 30 degrees on Sunday.

But how does it compare to what we’ve seen so far?

Early October brought a warning that the bush capital could see its warmest day since April, while its final days saw the mercury plummet as rain clouds gathered.

Ms Gamble says it was all driven by the “overall state of the climate” – in other words, larger-scale phenomena and patterns that influence our day-to-day weather.

As for what that means for spring, Ms Gamble says it’s too early to tell.

The Southern Annular Mode (SAM), a belt of winds across the Southern Hemisphere, is expected to enter a neutral phase in the coming weeks, which should improve conditions.

“Due to the seasonal weather patterns, they tend to shift a little bit further south, and that’s why Canberra gets those hot, dry summers with fewer fronts coming through and bringing that wet, cold weather.”

Canberra is looking at a warmer-than-average November, with an 80 per cent chance of above-average temperatures in the next fortnight.

Ms Gamble says the rest of spring could still be wetter than average, meaning the capital could see more than its average November rainfall of about 70 millimetres, but it’s impossible to say by how much.

“It’s not a really strong forecast.”

A negative phase of the Indian Ocean Dipole is expected to bring wetter-than-average conditions across parts of Australia for spring and summer before it resolves.

Southeast Australia, including coastal areas of NSW, could see thunderstorms in the coming weeks due to warm waters off the coast (and in the state’s northeast).

“That can provide a little bit more moisture and energy that can enhance the severity of storms.

“We are expecting perhaps a little bit more storm activity this year, just due to that pattern.

“Obviously, Canberra has seen some decent storms over the years!”

And it’s now official.

Sydney and Brisbane both have observed their hottest October on record.

As usual, we won’t await the corrections from the ideological zealots with egg on their faces, have they ever got anything right?

😂😂😂👨‍🦯👨‍🦯👨‍🦯

We will, however, await their standard bleating when there is a cold day next winter. Like clockwork.

https://www.weatherzone.com.au/news/warmest-october-on-record-for-sydney-brisbane/1890984

Take temperature measurements at sites long term. Owing to urban expansion or just increased population, vegetation is reduced, roads, buildings, concrete increase. These naturally raise the temperature readings at that site, the heat island effect.

If you were a fool rather than a scientist, you might point to the local change without thought for those distorting factors but scientists know that they have to correct for the part of the local rise which does not represent real long term trends.

Having done that, they observe that there is still an over all rising trend. That is global warming, recognised by virtually every climate scientist alive and the great majority of Australians today. If scientists did not do their job, we might things were even worse, bad as they are. Seano’s link explains this in more detail, and is worth the short time it takes to read.

Even the deeply conservative commentator calling himself Penfold has written here on Region that he agrees that increased CO2 in the atmosphere is causing global warming and that humans have contributed to that. Yet that same commentator spouts “do nothing” alongside various falsehoods or misleading comments about the work of scientists whose care with processes he has never understood, because he is driven solely by politics, not an interest in real information or actions.

Better tell seano, he’s adamant there’s no such thing as homogenisation.

Capital Retro12:05 pm 31 Oct 25

Penfold, if you are not on peer level with every climate scientist alive you are not cool.

We know all this climate stuff is so binary for you Axon, if you swallow the ideology then you sign up to the Chris Bowen church of trillion dollar policies, the scaremongering and inability to think about anything the church decries. Nuclear, for example.

This will come as a struggle but there’s a wide gap between “do nothing” and wreck the economy. There’s little point trying to explain this to you but with power prices surging, our standard of living going backwards for three years, industry shutting down and not any difference to temperatures, some of us reject the approach.

Seano understands elements of science correctly as indicated by his reference, Penfold. You do not, and never have.

I see you have no argument against my example nor against the explanation by two Professors in the field of climate science, linked by Seano. Science is too hard for you, and I can say that based on long observation of your wibble here, not just this event.

Wind power generators are taking energy out of the wind. The wind is what we call see when nature equalises pressure and temperature.

Penzero talking about others having a binary attitude is the most ironic statement seen on this website.

The lack of self-reflection is hilarious.

Not only do wind towers extract energy from the air, like energy from rivers and tides, but we are sucking it directly from the Sun! Good heavens! What’s a Henry to do?

By the way Henry, what was the ultimate origin of coal and oil? Are you busy making more?

Well we should all be in awe of your brilliance Axon. Though tbh I’m more in awe of people like Bill Gates and Tony Blair who’ve spent years preaching at the climate church alongside you and are now waking up to reality. Bill’s even embracing nuclear power, imagine that.

But on science, maths and well, basic logic, do you ever wonder why power prices have gone up 23.9% in 12 months despite climate nirvana telling us they’ll go down ?

Do you ever wonder how our standard of living has gone backwards for three years as we waste trillions on climate ?

Do you ever wonder why, after your scientific heroes told us the Paris agreement saved the planet 10 years ago, that it turns out it hasn’t ?

Do you ever wonder why the seas haven’t risen, Antarctic ice grows, Pacific islands aren’t sinking and BOM fiddle with temperature records ?

Do you ever wonder why science can’t explain the relationship between CO2 and planetary warming ?

Of course we know the answer to all those question – no. To question any of these would be to step outside the comfort of the warm snuggly blanket and religion known as climate nirvana. What lies outside those confines is too scary to contemplate isn’t it.

How do you get on that peer level CR – are there books to read, are there pills to take, does burying the head in the sand or wrapping up in a cocoon help ?

Hmm, seven paragraphs by Penfold in his longer recent reply, and misinformation or straight falsehoods in every one.

The only church around here is Penfold’s Church of Absolutism to preach nonsense.

What is the relevance of the existence of nuclear power overseas, Penfold? None of the economics, need or relevance stack up in this country. This is well known.

Did you notice withdrawal of the electricity rebate? To quote the ABS:
“Excluding the rebates, electricity prices would have risen by 4.8 per cent in the September 2025” and
“annual rise in electricity costs is primarily related to State Government rebates being used up by households”.
Yes, Penfold talks rubbish, being clueless about the real world.

By the way, where did I ever say prices would fall, Penfold? Ever heard of inflation, for example? It’s a thing, you know. There is also investment in delivering cheaper energy to meet increasing demand. Investment is the expenditure of resources for future benefit.

No, scientists did not say the Paris agreement would save the planet ten years ago, in part because “saving” assumes action which is only in recent years accelerating. Even your straw man is made of dandelion fluff.

Seas have risen, with record highs in recent years. Antarctic ice is decreasing, with record lows. Rising seas are eroding islands. BoM did not “fiddle” anything. I explained this clearly above. You preach bulldust. How does it taste?

Science showed that relationship back in the 19th century. In fact you are on record agreeing that increasing CO2 promotes global warming, and humans contribute to that. Only fools pretend otherwise.

The answer to any question from Penfold is that Penfold seeks to mislead, misinform, or talk purest nonsense, and can never, ever, back up anything he claims.

Love it Axon, despite all the links that i give you, you’re now claiming no evidence ? One of the things i like about this forum is it provides a way to educate people who have developed fixed but baseless ideas and beliefs. So in the sprit of lifting up the knowledge pool, here’s a few facts to help.

Growing Antarctic Ice:

https://www.livescience.com/planet-earth/antarctica/nasa-satellites-show-antarctica-has-gained-ice-despite-rising-global-temperatures-how-is-that-possible

Record Great Barrier Reef coral in 2022 (despite all the gloomy predictions):

https://www.aims.gov.au/information-centre/news-and-stories/highest-coral-cover-central-northern-reef-36-years

Pacific Islands Rising:

https://www.abc.net.au/news/2021-01-08/why-are-hundreds-of-pacific-islands-getting-bigger/13038430

It’s amazing what a few Google searches can deliver. And the good thing is these are observed facts, not future forecasts of impending dooom which will never come true. Though here’s one of those:

https://theconversation.com/study-finds-2-billion-people-will-struggle-to-survive-in-a-warming-world-and-these-parts-of-australia-are-most-vulnerable-205927

Bill Gates disagrees. Who’s right ?

“One of the things i like about this forum is it provides a way to educate people who have developed fixed but baseless ideas and beliefs”

Inception level ignorance when Penzero’s own comments disprove themselves.

“It’s amazing what a few Google searches can deliver”

You probably should get a licence for that cherry picker, but at least you freely admit to relying on selective google searches rather than actual knowledge.

“And the good thing is these are observed facts, not future forecasts”

Like the most recent report on the Great Barrier Reef, showing an ecosystem struggling with mass bleaching?

As you’ve already been provided previously.

https://www.aims.gov.au/monitoring-great-barrier-reef/gbr-condition-summary-2024-25#:~:text=In%202025%2C%20hard%20coral%20cover,declines%20of%20up%20to%2070.8%25.

Penzero once again showing his disingenuous and bad faith arguments, whilst at the same time outing his own inability to understand, maths, science, energy, well actually everything really.

Nobodies falling for it, he can’t even troll with any success.

😂😂😂🤡🤡🤡👨‍🦯👨‍🦯👨‍🦯

It seems Penfold loves being shown up, or so he says. As chewy14 pointed out, his very links fail to support his claims, or deny them outright. There is ample other evidence against Penfold’s falsehoods.

Observe Penfold’s prevarication (dodginess): I said sea levels were rising and islands eroding, which they are.
Penfold replied with a 2021 article on accumulation and erosion of islands owing to reefs and tidal forces, prefacing with the fact of seal level rise. He then misrepresented the article to support island growth without discussing causes (or the mentioned rise), and wholly ignored the mention of erosion which was my only statement on that. Penfold relies on people not reading his links but believing his misrepresentations and cherry-picking.

Here is a very brief authoritative article on the facts of seal level rise: https://oceanservice.noaa.gov/facts/sealevel.html
The headline will suffice if you do not care to read it.
“Is sea level rising?
Yes, sea level is rising at an increasing rate”

Penfold mentions Bill Gates. That is nice for him. I follow evidence and broad science. Penfold seems to prefer slavish adherence to individual opinions, the basis of authoritarianism. This could explain why he also keeps accusing people of “following” some politician or other; he finds it too difficult to imagine independence, being locked into the hard right wing.

Penfold also avoids many of the rebuttals he encounters because, well, he was rebutted, and has no answer without repetition of falsehoods (which he will do in another thread).

Penfold does not deal with reality, repetitiously trying to drag others into his scam-like positions. Goldphish is an apt epithet for him.

Axon – lots of statements there about cherry picking, erosion and seals. You could have saved yourself all that embarassment by simply reading the title of the article:

“why-are-hundreds-of-pacific-islands-getting-bigger” ?

But you’ve got me on one thing – the goal of raising the knowledge pool has clearly failed.

Capital Retro2:33 pm 01 Nov 25

Penfold, all the questions and answers about climate change are in books published hundreds of years ago (before modelling was cool and tin hats were invented).

Where did I say some islands were not growing, Penfold? You try to mislead abjectly as usual. Others are eroding, as you failed to mention. Growth and erosion happen naturally when sea levels are stable yet you have failed to find any answer to the facts of sea level rise, a fact noted in the first paragraph of your own article.

Penfold does not deal in reality.

Capital Retro8:16 pm 30 Oct 25

“the mercury plummet…..”

That hasn’t happened for years.

The BOM now uses electronic devices which are so sensitive that a passing thermal will increase the temperature a full degree for just a couple of seconds. A mercury thermometer wouldn’t react at all and all the measurements that were the previous records were taken with mercury thermometers.

BOM now homogenize temperature readings by mixing in other atmospheric readings so I give no credit to their claims.

That’s a good point you raise CR. With sensors being digital these days, BOM don’t need to adjust temperatures themselves, they can sneak some code into their sensors to do it for them without anyone being any wiser.

Perhaps to counter this, you and I could setup a “Truth in Temperatures” business to, as Don Chipp would say, to “keep the bureau honest”. We’d use modern equipment to take certified and peer-reviewed readings and compare them to BOM’s.

CR and P, the business name almost rolls off the tongue too.

The bom are not fiddling the temperature data.

Homogenisation explained here for the clueless.

https://theconversation.com/no-the-bureau-of-meteorology-is-not-fiddling-its-weather-data-31009

“Tin Foil Temperature & Tools”

For all your cooking needs.

So BOM fiddled with the data to make warming look more pronounced.

But they didn’t fiddle with the data. Got it 🔥

“So BOM fiddled with the data to make warming look more pronounced.”

This, did not happen. Got it.

“Got it 🔥”

Narrator:

“as usual, the hapless Penzero had not, indeed, got “it”.”

Capital Retro12:23 pm 31 Oct 25

Yes chewy, when you have your back to the wall your only response is meaningless pap.

You would be too young to remember how body temperature was taken years ago using a mercury thermometry placed under the tongue for five minutes with the oral orifice closed whereas these days an instant reading is obtained by inserting an electronic sensor into an ear.

There was also another body orifice the mercury thermometer could be placed in and I am sure you would choose that if it were still available.

For Capital Retro, statistics is a foreign country.

I guess it is pretty unfamiliar for many people, but only a few like Capital Retro care to froth out their ignorance of it.

Back against the wall?

LOL

Your comments reflect such a lack of understanding, dripping with discredited cooker conspiracy theories.

The only response to that level of delusion is to point and laugh.

With all your experience with Mercury in the last century, you probably should have avoided using it as an additive for your Tin Foil hat.

Although it does explain a lot.

Capital, I like how you have a shot at Chewy over “pap” and then demonstrating no apparent self-awareness proceed with an off topic, puerile attempted insult.

If you want homogenisation explained you can find it here:

https://theconversation.com/no-the-bureau-of-meteorology-is-not-fiddling-its-weather-data-31009

CR – get with the program. seano has now twice posted the same link from the (non-scientific or peer reviewed) The Conversation which is adamant – by fiddling with climate records the Bureau is definitely NOT fiddling with climate records.

What can’t you undertsand about that ? How hard is it ?

In fact they tell us that “Cherrypicking weather stations where data have been corrected in a warming direction doesn’t mean the overall picture is wrong.”

They continue …. “Data homogenisation is not aimed at producing a predetermined outcome, but rather is an essential process in improving weather data by spotting where temperature records need to be corrected, in either direction. If the Bureau didn’t do it, then we and our fellow climatologists wouldn’t use its data because it would be misleading. “

So there you have it – if they didn’t fiddle with the data then the data would be misleading.

https://theconversation.com/no-the-bureau-of-meteorology-is-not-fiddling-its-weather-data-31009

And one last thing – despite there being not a single statistic on your thread here to date, listen to Axon when he says “For Capital Retro, statistics is a foreign country.” (sic)

This is pretty funny, and quite an interesting proof (in the vernacular sense). After Capital Retro said that a sensitive thermometer made point measurements, suggesting this was a problem, I observed that he obviously lacked knowledge of statistics.

My comment was too difficult for Penfold who says he does not understand how it follows. Given he has demonstrated here that he did not make it through proportions back in primary school, it is no surprise he (and Capital) seem never to have heard of an average let alone variance, smoothing, time series and so on.

Capital Retro’s comment showed wilful or actual ignorance, as Penfold always does.

It’s an explanation of how homogenisation works, it’s not a peer reviewed paper and wasn’t offered as one. Your willingness to demonstrate your ignorance out of spite never ceases to bemuse Penfold.

If you want to see the peer reviewed research it’s a simple google search to find several papers on the topic, of course we both know that google search will never happen.

As I’ve pointed out to you before, you don’t have to beclown yourself Penfold, there is no requirement.

What’s “proportions back in primary school” mean Axon ? We didn’t do a subject called proportions but it sounds like you did. As for smoothing, time series, Z-tests and standard deviation, well that wasn’t primary school either.

But it sounds like smoothing is your thing. And you’ll be deligted to know it’s the bureau’s thing too, smoothing out those pesky low temperature numbers which “distort” the actual temperatures and replaces them with their preferred higher outcomes.

But maybe we should go way back to the start, back to June 26, 1989. The planet had until 2000 to act, or “coastal flooding and crop failures would create an exodus of eco-refugees”.

In fact “entire nations could be wiped off the face of the Earth by rising sea levels”.

https://tallahasseereports.com/2019/03/09/a-1989-ap-report-nations-wiped-off-face-of-the-earth-by-2000/

I’ve been absolutely petrified by climate change ever since …. and so has the boy who cried wolf.

Capital Retro8:39 pm 31 Oct 25

The Conversation?

You have got to be joking.

Capital Retro6:47 am 01 Nov 25

Statistically, most comments on this thread are average but yours always try to be above average.

Next time I am at ED at the local hospital and they take my temperature I will insist that they factor in variance, smoothing, time series and so on lest or they will be seen to be ignorant.

Penfold and Capital Retro continue to flounder, too easily picked apart so I will not tell other people what they can already see.

By the way, Retro, when you are at ED they will not use a mercury thermometer. Will you flounce out?

The funny thing Capital is you’re now attacking The Conversation in lieu of an actual argument. You and Penfold aren’t interested in facts, you’ve had homogenisation explain to you and you can’t challenge that, so you resort to these childish tactics.

Comparing two different and unrelated things and being smug isn’t the clever tactic you seem to believe it is.

You’re effectively conspiracy theorists who reject anything that doesn’t support your preconceived bias. I can’t imagine it’s a great position to be in to constantly have to reject facts to make the universe you live in work but I do know that conspiracy theorists can generally be dismissed.

CR – hopefully you don’t have to go to the ED. But if you do given how long the wait times are you might find when you come out that the bureau has homogenisesd more temperatures and the headlines claim that we’ve passed 1.5 degrees. In Cuba, or Antarctica, or Siberia, or Seanostan, or somewhere at least.

In this universe Penfold, the real one, the logical fallacy you’re engaging with is comparing two unrelated things as if they are the same.

logicallyfallacious.com/cgi-bin/uy/webpages.cgi?/logicalfallacies/False-Equivalence

You don’t have to beclown yourself as I may have pointed out to you before.

Penfold, I see now that it is your brain that is homogenous, not a fold could be found in the cerebral cortex.

The cognitive dissonance must really burn, having to continually make up larger and larger conspiracy theories in an attempt to ignore the continual data that doesnt match up with the ideological bias.

But of course we don’t expect anything else, when the intellect level isn’t high enough to properly understand the topic in the first place.

Capital Retro2:38 pm 01 Nov 25

My real fear Penfold is that there will be no electricity to power the electronic instant thermometer and the only mercury one they can find is a rectal one.

Fortunately, they will have candles to warm the instrument.

What do you mean “unrelated” seano ? Surely there’s a close relationship between fallacy and clowns, and you do seem rather besotted by the latter.

CR – fear not, i’ve got a mate who runs the local Canberra Hostpital ED from time to time

And he assures us that the ED has backup batteries which get their power from nice cheap reliable coal and gas, so the thermometer should be safe.

You shouldn’t need candles but with Bowen running the show, you can never be too safe. Axon seems to have slipped into mental health diagnosis mode, so i’m really hoping that if you do indeed need the ED for any reason, my buddy is running things and Axon has returned to spending quality time with Alice, in Wonderland.

The diagnosis I made was not of mental health, Penfold. You do not even know that.

ROFL

Measuring the temperature of the human body is not the same thing as measuring the temperature of the atmosphere Penfold, your puerile attempts at false equivalency are laughable.

The weird comments from you an Capital on thermometers and ED says a lot about you too and your lack meaningful contributions.

Capital Retro2:11 pm 04 Nov 25

Is his name Racheal?

Noteworthy that based on today’s maximum recorded temperature and the forecast for tomorrow, Sydney is still on track to observe their warmest October on record. As was outlined by those rabid lefties, Sky News on the 16th October.

A couple of colder days not being able to shift the outcome for the previous weeks of unseasonably warmer weather.

The correction from those who don’t understand numbers or maths will as ever remain outstanding.

https://www.skynews.com.au/australia-news/weather/sydney-is-on-track-for-hottest-october-on-record-as-city-experiences-major-heat-wave/news-story/43ecbda5f3e2dbed951cf581dbba3350

Apparently making straightforward factual statements based on recorded data is “yelling”. 😂👨‍🦯

ABC 17th Oct:

“Unseasonable temperatures have lasted for weeks along the eastern seaboard — with Sydney, and possibly Brisbane, on track to observe their warmest October on record.”

On Tuesday it felt like minus 5 at get up time, very strange for the end of October.

Other noteworthy October weather issues have been the ABC yelling “likely the warmest October on record” on October 17. The correction remains outstanding.

And how about the BOM website, how can a government agency stuff something like that up so badly ? Did they do any user testing ?

They did, in the staff canteen over morning tea

Wonder if that was before or after they discussed “homogenising” temperature observations again.

Fiddle with the website, fiddle with the temperatures, all in a day’s work.
