Wow that is a big gust!!

Possibly one of the warmest nights ever (inc. summer) at Obs Hill last night, only got down to 25.6C. But yesterday 9am was 23.0 so that will be the min as Yep said. There's a slight chance that the temp could drop below 23.0 before 9am today but hopefully not.

Still an extraordinary effort though.

There will be some incredible minimums at places where yesterday warmed up really quick. Scone Ap for example, the min is just 25.8C!! Some records may be smashed by several degrees.

Quite a dusty looking sky out here, the eastern horizon in particular has a brown tinge to it.

Holy hell, 29.9C at 0730, 31.8C at Tocal, 29.9 at Williamtown and even Nobbys Head at 29.2C.
Was slow to warm up yesterday, compared with Scone, so record minimums unlikely here.

Still pretty impressive to beat a record by that margin, even if it is a pretty short term record.

PS: Obs Hill beat it's September record by 1.0 degree with 23.0C as the min. Could've been higher than the November record as well if 9am yesterday was a bit warmer. Nov record only 24.1.

Interesting that Sydney Harbour had a Sea Breeze from the NE between 2-4am (only) last night.

Is that a record for the latest ever NE Seabreeze on the Harbour?

I think a weak cool change passed through Sydney around 7:00AM, with a subtle wind shift from N of W to S of W. There was a small drop in temperature from 28 to 26 at OH. The temperature has been rising only very slowly since then, to 27 now. This contrasts with sites in the Central Coast and Hunter, where temperatures are now into the low 30s.

Finally, last nights heat hit's the Sydney press this morning.

http://www.smh.com.au/environment/weathe...923-gynjoc.html

Quote:
Much of NSW would have felt like they spooned a hot water bottle last night.

Sydneysiders especially would be forgiven for thinking they'd slept with the heaters on as the city sweltered through one of the warmest September evenings on record.

Temperatures in the city did not dip below 26 degrees on Saturday evening, an event weather experts describe as "phenomenal".

"We expect lots of variability for this time of year, but not quite to these extremes," Bureau of Meteorology senior meteorologist Jake Phillips said.

Sydney's overnight minimum temperature was 25.7 degrees, beating the September record by 1 degree which was set in the usual 9am to 9am 24-hour reporting period.


Yes the overnight minimum temp was 25.7 degree.
But as posted on here overhight, that was not the minimum temp for the 24 hour period

As the 24 hour minimum temp was 23.0 degrees at around 9am yesterday morning. 1 degree above the previous record max min Sep temp of 22.0.

The BOM does not help with the way it lists minimum temps on their observations page, in not actually displaying the 24 hour minimum temps, and thus likely confusing any media that go there to get what they think are 24 hour minimum temps. (Including the media owners of this website)

The 24 hour minimum means record high minimums, and sometimes even record low, are almost impossible to beat, as well as being unrepresentative of what happened at night.

So does anyone or anywhere keep records for NSW overnight maximum minimum temps from between say midnight and sunrise?

Record lows arent impacted. Low maximums can be though.

SMH has actually done pretty well there IMO to describe the actual overnight min but then clarify the nature of the 9am reset

The BOM are still going for 33 across Sydney in their 10:17 update, in spite of there having been little warming since 7:00AM. At some stage later today, it will gradually cool down.
