October 2023 Summary (climate, snow, hottest, warmest)

[greysrigging]

Bloody hell ! Thank **** October is over ! One of the hottest and driest Octobers across the Top End since records began in 1941 ( at Darwin Airport )
October is a 'build up' month in the deep north, but this year, with an El Nino and positive IOD in full force, it has been dry as a dead dingo's donger, hot as buggery, bushfires burning still, and no thunderstorms ( at least, none in the Darwin 'burbs )
Dryest Oct since 1982 when the Airport recorded 1.2mm
And, this 'dry season' is the longest and dryest since 1953 when only 0.5mm fell between April 20th and November 1st.
2023 we have recorded 1.6mm between April 28th and Oct 31st.
My tropical garden is suffering big time....
Quite a few consecutive weeks heatwave warnings have been in force and I believe there are some monthly mean records set as well, but I need to fact check this....
It's been particularly hot inland from Darwin... ie out at Kakadu and in the Douglas-Daly Districts of the Top End.

Perth, Western Australia October 2023 summary

Max monthly temp: 36.5°C
Min monthly temp: 7.2°C

Mean Max temp: 26.2°C (+2.9°C)
Mean Min temp: 13.4°C (+1.8°C)

Rainy days >1mm: 2 days (-3.9 days)
Rainfall: 8.2mm (-32.2mm)

Sunshine hours: 319.9 hours (+22.3 hours)

As you can see Perth was significantly warmer than average this month, significantly drier and a bit sunnier than average. I'm really hoping these above average differences don't continue into summer. I'm loving the dry and sunny weather but it is getting very hot already with plenty of days in the early to mid 30's in mid spring.

A warm and gloomy October. 2.7F over the 2003-2022 average, and 3.6F over the 1980-2010 average. 2021, 2007 and 2017 were warmer among recent Octobers though.

Some data was missing, mainly for precipitation, so I had to fill in from the next closest stations in Fergus.

Pretty interesting how the monthly high from April to October has been within a very narrow range compared to the rest of the year. I'm guessing November and December will have monthly highs in the 50s (maybe even high 40s for Dec), but we'll see...

A pretty warm YTD (definitely above average), but not as warm as 2012.

Compared to the average of the last two decades, here's how this year has been doing.

Jan: +7.4F
Feb: +5.6F
Mar: -0.5F
Apr: +2.9F
May: -1.3F
Jun: =0.0F
Jul: -0.4F
Aug: -2.7F
Sep: +1.4F
Oct: +2.7F
YTD: +1.6F

Coming from a granted record-breaking hot year, it may felt like a coolish month, but still it was slightly above average! And still a lot of rain deficit to overcome, even if the signals of an El Niño turnaround are clearly becoming stronger.
