All this talk of heat events. Reality is the heat moved in about 5 weeks ago and hasn't really gone anywhere. The heat events you are talking about are just the days when the westerly blows it close to the coast.

In Dubbo we have had 5 straight days over 40. Only 1 day in the last 21 days below 35. In the 7 day outlook 37 is the best ahead, with another 4 x 40 degree+ days coming up. Relentless.

Looks like the heatwave will continue here in Canberra for at least 1 more week as the heat re establishes. Only 1 day of reprieve on Monday the 6th of January with a downgraded rain forecast to virtually nothing. Possible all time record temperature tomorrow with 42 degrees (record is 42.3).

The highest we had at our place in a valley in Hornsby shire about 20 years ago was 47.7c.

The BOM have updated the forecast at 9:24AM and have stuck with yesterday's numbers for Sydney - basically 45 West of Olympic Park, 46 in the outer West, low 40s over most of the rest except near the beaches and the Harbour where it's low to mid 30s. At the moment it's warm and sunny with a light NW'er and hazy light blue skies. The smoke's come back at ground level in the last couple of hours.

There doesn't seem to be much wind, apart from the sea breeze once it gets going. It's now in the low 30s over most of Sydney. The sea breeze has started on the coast. The Southerly is nowhere to be seen.

EDIT. I'm away from any bushfire prone area but some family ilive near bushland. It's a very anxious day for many. Best wishes to all in the shadow of bushire danger and may evreryone get through today safely.

My guess about the increase in bat activity is it is being caused by the fires destroying their roosters and food supplies. Fruit bats also dislike heat and will do their best to avoid it, by locating to cooler areas. At least the bats have the ability to out run (fly) the fires.

In Newcastle, where you can usually rely on the coastal influence to counter the worst of a hot day, it has just gone above 41 degrees at 11am. The worst of it is the hot dry wind, as if God left the oven door open.

Note this is a home recording a street away but warmest ever home recording since the station was set up in Jan 2018 and blows away the previous 46.5 degree record. Bankstown is at 43.4 as of 12:50.

It’s interesting that Newcastle and Ulladulla, as examples, have hot forecasts and no sea breeze, whereas Sydney and the Illawarra do.

42.5C here. Hotter than NYE already (well placed amateur thermometer)
Actually BOM has nailed the forecast Seabreeze at OH and at Sydney Airport along with the Illawarra just bar Kiama which is running a NNW. Going to get very uncomfortable for the coasties soon.
Reason why I won't count Newcastle so far is because that valley effect can see Newcastle get overrun by Northwesterlies.

Where are you guys getting the blow by blow temps for Penrith?, all I can see is the BOMs weather observations that are updated every 30mins plus occasional peaks, none of which show 48.1c.

Local Bankstown record beaten 46.4 degrees at 2:04pm beating out the 46.1 on the 18th of Jan 2013. Not going to lie the mid 40s Western Sydney Heatwave has come 1-2 weeks early it is usually mid Jan. This time it's been late December and Early Jan. But thankfully this should be the last heatwave as the heat engine gets turned off in Central Aus and WA.

The smoke plumes on radar tells the story of what’s happening in southern areas atm!

That's what I'm looking at, but although it says it updates every 10mins, all I can see is every 30mins, what am I missing?

Can you post a screenshot? If you click into the individual site it is only every 30 min. If you stay on the general Syd Observations page it is all sites updated every 10 minutes (generally at 2:34pm for data up to 2:30 etc.)
