Coldest March day in 15 years set for Sunday

Jacob Cronje, a senior meteorologist at Weatherzone, said last year’s coldest minimum in March in Sydney was 14 degrees. “The coldest it’s been in the last couple of years on a March morning is 12.8 degrees,” he said.

It will get down to single digits in other parts of NSW on Sunday, Mr Cronje said.

If it drops below 12.1 degrees, it will be the coldest March day since at least 2005.

Around the country, it should get cold enough for snow to fall in Tasmania, Victoria and southern NSW on Saturday, with enough moisture in the atmosphere to produce 2-5cm of snow at some of Australia’s main ski resorts.

Despite this, the month as a whole looks to be “well above-average” in terms of minimum temperatures, with the current mean sitting at 19.4 degrees. The average minimum temperature for the month of March is 17.6 degrees since records began in 1859.

Sydney is coming off its third hottest summer on record, trailing only 2016-17 and 1990-91, the Bureau of Meteorology said.

Mr Cronje said that lingeringly warm sea surface temperatures had led to increased humidity, which made evenings feel even hotter.

The average maximum for this March is 27 degrees, more than two degrees above the average March since 1859, but with a couple of the coldest days of the month still to come. Three of the hottest months of March ever in Sydney came in the past four years.

Up to 25 millimetres of rainfall and winds of 45 km/h could lash the city on Saturday, before a chilly end to the weekend.

There’s a potential for thunderstorms on Friday evening but “nothing terrible,” Mr Cronje said, before the majority of the rain is predicted to fall across Saturday morning, then giving way to a clear afternoon and evening.
