Where are you located that is cold? @Radiohead
Yeppoon has been cooler at night compared to last year and days are almost as hot as last year.

Yeppoon has been cooler at night compared to last year and days are almost as hot as last year.
Newcastle, not cold, just cooler than usual, some overnight minimums got down to 15-16, doesnât usually get below 19 at night.
Its actually been one of the nicer summers Iâve experienced for a few years. Only been a few humid days, havenât had a warm to hot night at all yet (21 is probably the warmest Iâve seen, tomorrow is supposed 22 o/n min).
We had 27.5 deg this morning as a min the usual temp is 24.0
Also is Newcastle near this cooler than average patch of water ?
Yes, i think we are at the northern end of it.
27.5 deg morning!? ouch
Weâve had 228mm yet the lawn is looking dry as the last decent rain was over 10 days ago and weâre on sand and the sun seems to be intense with no cloudsâŚ
Yeppoon.
That 37 deg day we had a dp of 20 deg and 38 percent humidity
The other one the dew point was 23 deg and humidity in the 40s.
The reason for the more moderate humidity (and hence cooler minima) on the NSW coast is probably due to a fluctuating Southern Annular Mode:

We had a strong negative phase in December, which encouraged more cold fronts from the Southern Ocean and less tropical influence. The brief positive phases have coincided with wetter and stormier pulses; note there is about a two week lag between the SAM phase and conditions on the ground. The positive phase around NYE/NYD corresponded well to the severe storms around the 13th of Jan.
SAM has trended positive over the last couple of days, so a wetter humid start to February might be on the cards for the east, particularly now that the northern tropics have a bit of monsoonal activity at last. Positive SAM phases have become almost the norm in recent years, which partially explains the abnormally wet conditions in NSW. It was a stubbornly positive SAM that continued the wet and stormy conditions last summer despite an El Nino in place. So best to watch what SAM is doing as it can make a mess of long term predictions.
The SAM pretty much governs the position of the subtropical high pressure belt in the Southern Hemisphere. Positive SAM means the highs tend to be further south than the mean position, âopening the doorâ for tropical troughs to form in the absence of high pressure. There are also more easterly winds than usual. The reverse is true in a negative SAM, higher pressure and more Southern Ocean influence and more westerlies, which means less rain in summer and more changeable weather with alternating cold fronts and heatwaves.
In Bungendore itâs been warmer than average overall (particularly in December thanks to the drying influence of the negative SAM) without any severe, long lasting heat. This Tuesday may be the hottest day of the summer with any luck; after the first or second week of Feb things start to cool off on the tablelands just by virtue of the longer nights.
If youâre in Perth, you want a negative SAM though as that tends to bring more westerly seabreezes. You donât want easterlies.
New bushfire emergency in Victoriaâs west, not far from The Grampians one, in the Little Desert National Park near Dimboola (between Horsham and Nhill), town told to evacuate. Some reports saying the fire spread rapidly and homes/lives at real threat.
Western Highway also closed from Horsham, again not long after Grampians, a national highway and key artery to Adelaide for logistics. CFS crews called in to assist the CFA from South Australia.
Not helped by the gusty change that swept across the state this evening, including lightning/storms.
It was another 40 in Melbourne today, higher in western suburbs and north-west of the state.
Should be news on this tomorrow morning Iâd expect, ABC 24 with the scoller warnings, as well as radio and some online mastheads. Minimal social media currently.
At least when the Sydney region gets high temperatures like this, they only usually last a day or two.
The cool change this evening will be very welcome still!
Not real nice outside today.
Sunny yes, but temps around 37 degrees with the dew point still around 20-22 degrees in some parts⌠yuk.
Observatory Hill in Sydney 35 degrees, 24 deg dew point right now!
39 degrees right now in Brighton-Le-Sands.

The chance of a tropical cyclone developing off Queensland's coast is increasing tonight. #9News @LukeBradnam pic.twitter.com/cMS7QVurhc

Another heatwave (3rd or 4th this summer already?) coming to Melbourne, with 4 consecutive days in the high 30s from Saturday, Friday also above 30. Monday and Tuesday when winds become proper northerly and stronger could even see another 40 day or two.
February is traditionally the hottest month, this was when the Black Saturday bushfires occured 16 years ago and also recorded the highest capital city temp (46 degrees), just a week after the Jan 2009 heatwave where there was about a weekâs worth of 40 degree days, coming out of the 2000s drought.
Yes, traditional Tasman Sea blocking high that points the nose of the heat dragon at VIC and SA. We are well overdue for one. This may produce some long haul tropo to NZ for NSW coastal residents if it hangs around long enough (and thereâs not a trough lingering, producing storms).
NASA has done a piece on Victoriaâs bushfires including a spectacular satellite image:
The latest satpics are great whenever there are bushfires; you can easily track the smoke and prepare for poor air quality that way. Some of the smoke from the series of western VIC fires has been carried up as far as central NSW, particularly during strong cold fronts.
BoM Official forecast isnât as grim as that⌠700 mm over the next 4 days, but thatâs still an awful lot of rain.
I hope that doesnât cause too much flooding⌠I recall back in 2019 with that horrible flooding, it was 1,000 mm of rain over 7 days that caused thatâŚ
But thatâs not sounding too good.
Thatâs the problem these days, itâs either too much rain or nothing at all. Iâm sure anyone in Western VIC would be happy with 1/40th of that.
