Sydney has woken up to its coldest Good Friday in four years after an overnight change.

Thursday was the hottest day since mid-January as the mercury hit 33 degrees. It was also Sydney’s hottest day this far into autumn in 27 years.

This morning was noticeably cooler though, following a change that brought 3mm of rain to the city overnight.

Temperatures in the city dropped by 3 degrees in less than an hour around 7pm last night as westerly winds arrived. Shortly after, rain began to fall, delivering 3mm between 7pm and 11pm. The airport experienced a temperature drop of 5 degrees in half an hour when showers arrived. The heaviest falls were in the north and west, where Turramurra picked up 6mm and Bankstown just over 5mm. Southwesterly winds behind the change gusted up to 56km/h on Sydney Harbour just before 2am.

Cool air in the wake of the change made for a chilly morning, dropping to 17 degrees in the city and just 11 degrees in Campbelltown. It will also make today the coldest in almost a month and possibly the coldest Good Friday in years.

If Sydney reaches its forecast maximum of 23 degrees today, it will be the coldest Good Friday since 2009.

Looking ahead, it will gradually warm up on the weekend, climbing into the mid-twenties each day. Another change on Sunday evening will then bring showers on and off for the rest of the long and also knock a few degrees off again by Monday, making it about as cool as today.

Sydney won’t experience a week as hot as the last one until the end of the year, with last night’s change ushering in the cooler months ahead.
