Sweltering conditions will develop across NSW this weekend, with Sydney expected to hit a whopping 36°C on Sunday afternoon. Should this maximum be reached, it would be Sydney’s Observatory Hill’s hottest day since January 26th, 2021 when conditions reached 37.1°C.

Meanwhile at Sydney Olympic Park where the Grand Final will take place, 36°C is expected on Sunday. If this temperature eventuates, it make it the hottest Grand Final day in the NRL era (both Sydney Olympic Park and Sydney Observatory Hill), eclipsing the South Sydney Rabbitohs vs. Canterbury Bulldogs from 2014 which reached a high of 34.7°C. Thankfully, conditions should cool off dramatically by 7:30 pm AEDT with temperatures dropping back into the mid-20s. Spare a thought for the Women’s NRL Grand Final though - with kick-off scheduled for 3:55 pm AEDT, game time is at peak heat levels.

A cold front and trough will approach from the west during the day with increasing west-northwesterly winds, dragging hot air from the interior of Australia across the east coast. Widespread gusts of 40-60km/h can be expected, with gusts to 90km/h likely across southern parts of NSW and alpine regions. 

Dry conditions will accompany hot and gusty winds with a significant fire threat likely to develop, particularly for the Hunter, Greater Sydney, Illawarra, and South Coast.
