Heatwave conditions in Sydney this week, it hit 40c in the western suburbs yesterday, 38c in Parramatta which is about the mid point between coast and blue mountains and low 30’s on the coast. Night time temps have been oppressive with theme 25c+ until after midnight.
Thunderstorms today and some rain forecast for Friday and Saturday with temps back down to the mid 20’s, but will pop back about 30c again by Sunday.
It’s not so unusual to get hot days in November in Sydney..basically it’s to do with how the high pressure ridge pushes across Australia at this time of year. The higher placement of the ridge allows for a NW wind drag from the centre of Australia as the high exits Australia and enters the Tasman sea. When the monsoon really ramps up over the top end, it has the effect of squashing the high pressure ridge south and rather than NW winds around the high, you get damp humid easterlies which dominate Sydney’s weather between January and March. This is why the bushfire season in Sydney is generally from mid October to early January.
