Sydney will struggle through a very warm night before confronting the hottest start to summer in eight years.
Temperatures soared across the Sydney Basin on Friday as a very hot air mass was drawn across the region ahead of an approaching trough.
The city managed to reach 29 degrees, which is five above average, although failed to climb higher due to a sea breeze. Further west though, Bankstown and Parramatta both reached 39, which is 14 above average and the hottest November day in three years.
Tonight will see the mercury remain in the mid-to-high twenties as heat lingers over Sydney, making for an uncomfortable night. This is around 8 degrees warmer than usual.
The warm start to Saturday will help western suburbs climb into the low-to-mid 40s during the day. The city and coastal suburbs are likely to reach the low to high 30s, thanks to strengthening northwesterly winds holding out a sea breeze. The sea breeze will bring humid conditions, particularly during the afternoon.
Saturday night will start out warm, although as the trough moves over the city during the night, southerly winds will bring cool relief.
Sunday will be significantly cooler than the previous two days, reaching a top in the mid 20s through much of the Sydney Basin.
