It also helps that the Snowies are there because you get downslope winds from them which makes it warmer than the CT's that have no mountains above 1400m. In winter it's quite common to see Cooma warmer than Canberra from the downslope winds.

So. Wheres the real southerly. Need some wind to cool down the roof so i could finally get some relief.

Had a few light rain drops earlier this morning.

Badgerys creek AWS came up and now Penrith AWS is down. Hopefully its up soon before the next heatwave.

I'd hazard a guess and say near the clearing edge on the Southern side of the cloud band crossing the state, which is consistent with Dipole's observation.

That being said, from the Central Coast southwards, I don't think it will get much warmer than it is now. The cloud will probably hold the line until the real change arrives. However, it's still hot in the Hunter away from the coast.

Still hot outside, waiting for things to cool down.
Looks like the old Richmond RAAF record from Jan 1939 lives to fight another day, was never really challenged yesterday- the heat came too late.

It's been a most unusual weather pattern in the last 24 hours, excessive heat, a warm front, mixed with a cold front, showers well ahead of the real cold change. What next?

Strewth. Might also be why it can be at least >6° C colder in maximums around Eucumbene than at Cooma during the winter months—apart from being more exposed to SW frontal systems (i.e. farther west).

Cooma's average midwinter high straddles ~10.0° C, whilst up here it should straddle 4.0°-6.5° C; depending on altitude, as it ranges from 1,168-1,491 m AMSL.

Change came through around 3am this morning, the temp did increase by a degree, overnight low was 23.4c, No doona was required.

Can see the high cloud band approaching from the SW. Should be a pleasant humid day. Current temp 26.4, Dewpoint 23c Humidity 80%

Looks like the real southerly is moving through Kiama atm.

btw is anyone else feeling like the forum is a bit slow this morning?

The wind's picked up here from the South in the last half hour or so. However, it is still warm and humid, so maybe it's just another pretend Southerly. The sun was trying to come out a little while ago but it's closed in again.

It's quite warm in Sydney's West, pushing 30 at Badgerys, Richmond and Camden. I'm expecting it to cool down this afternoon, however. Meanwhile, the heat's still on in inland parts of the Hunter under sunshine, 36 at Cessnock, 38 at Scone.

Re last night's heat spike, Sydney OH reached 32.4, probably close to 10:30PM.

P.S. Re the forum, the site has definitely been slow this morning.

Yes still hot here,if I could afford it I would move to the coast somewhere.I think all summers from now on are going to be very hot inland from the coast

A light se wind has just came up here about half an hour ago, it will take a while to push the heat out.All we need now is a storm,but nothing the the radar.

howling 35 degree southerly here. No cool in it at all yet! Been blowing hard for 30 minutes and there has been a southerly for a couple hours or so. Even the relief isnt relief....

Well it’s certainly been a tad warm. Consequently I’m date watching like mad looking for the start of the very slow cooling of temps. As I do every year smile

Bit sad when even Anglers Reach and Cooma etc are so hot too. I loved mt time in Adaminaby because it was rarely too hot frown
10 days till we leave Bathurst hottest month and then I look forward to mid Feb because somewhere near then we should get a night around 10 degrees and THAT is a lovely event 😁😁

In the meantime, it appears summer is here 😁

Yeah nah, it isn’t common to see that. I dispelled the föhn stuff ages ago. Besides, Canberra has the Brindabella’s behind it which are higher than the 1400m mark you mentioned.

Mt Boyce (1080m), 36.1C

Orange AP (945m), 37.5C

Oberon (1088m), 35.5C

Remarkable really how uniformally consistent between not only the locations above but between them and the Snowies. What seems to stick out a bit for mind, and I think someone else mentioned it earlier, is that the slightly lower elevation sites like Bathurst (745m) for example maxing out at 38.1C, aren’t as far above the higher altitude locations as would be usually expected from not only altitude but the differences in topography of the higher altitude sites, ie, more air flow.

Adequate point regarding the topographic advantage(s), but this region still surpassed the CT's in terms of altitudinal-relative heat; I'm a good ~200 m higher Oberon, yet it only recorded 35.5° C vs. 34.7° C for Anglers (let alone Adaminaby town). Likewise Cooma VC and Cooma AP vs. Bathurst AP and Orange AP—similar applies.

Thereby, if you meant to say that the lapse rate was much swifter in the Snowies than in the CT's, then you are indeed correct.


No, I pointed out the lapse was more ‘text book’ in the Snowies compared to the CT’s. You picked Oberon as the comparison to Adaminaby but that was actually the coolest of the three I mentioned in the CT’s relative to altitude. Say you take 1C off of Orange AP’s max of 37.5C to give it the effective altitude of Oberon and Mt Boyce, a temp
of 36.5C and lo behold it runs as pretty good fit to your 34.7 at 1280m.

As for Cooma, it is by and large a treeless plain, trees go a long way in moderating both heat and cold, hence why it likely to be hotter. It is also a little more shielded from coastal influences than say Bathurst, the land around Nimatabel being higher than the BM’s.


Yes, the CT’s didn’t set any max records like down in the Snowies but this was far from a localised event to the SW of the state as you mentioned in your initial post. Temps were (and still are in places) in the upper percentiles of observations for most of the state excluding the coast, and, for consecutive days in theses upper percentiles.

Not all that many single-day records have been set in NSW in this heatwave at long-term stations, mainly because the most relatively extreme temperatures of this heatwave have been in southern inland NSW, which was also ground zero in 1939. However, this heatwave has been much more extensive than 1939, which was a non-event outside the southeast quarter of the country (indeed January 1939 was one of the coolest on record in WA).

Fohn effects arise because moist air going up one side of a range cools more slowly than the dry air warms up on the other side. It doesn't come into play in most extreme heat situations because there's no moist air to begin with, but it certainly is important in most W/SW flows in winter, hence the frequently lower maximum temperatures on the Central Tablelands than on the lee side of the Snowies (though Canberra 'benefits' at least as much in this situation as Cooma does).

Incidentally, Nimmitabel is the highest place in Australia to have reached 100F (back in 1968 when temperature observations were still made there).

And I don't think I'd mentioned it here, but the reason Badgerys was out for so long was that it was fried by a lightning strike.
