Warming up … Sydney is set for a week of hot weather. Photo: Andy ZakeliSydney is expected to bask in a week of above average temperatures, with the mercury forecast to climb into the late 20s until Sunday.

The temperature on Monday will heat up to a top of 27 degrees in the city and 29 degrees in the western suburbs.

Conditions are expected to be similar on Tuesday, before a forecast maximum of 28 degrees in Sydney on Wednesday and Thursday. In the west, the mercury is forecast to hit 30 degrees on on those days.

That is above the mean maximum daily temperature for March of 24.7 degrees in the city.

Weatherzone meteorologist Rob Sharpe said a high-pressure system off the NSW coast was delivering on-shore winds to Sydney.

“We’re going to see a couple of showers in the next couple of days and then clearing into Wednesday as winds tend more north-east, north-west, depending on where in Sydney you are,” he said, adding that there would be mostly sunny skies on Wednesday.

Friday is expected to reach a maximum of 27 degrees with a possible shower, while Saturday is forecast to be the hottest day of the week, reaching 29 degrees in the city and 31 degrees in the west.

A stronger frontal system will bring a gusty cool change on Saturday night.

Sunday is presently forecast to reach a maximum of 26 degrees in the city, but that figure could be revised down, Mr Sharpe said.

“Sunday could be one of the coolest days since Spring,” Mr Sharpe said.

“[The temperature] will be pretty consistent out to Saturday, with just the odd shower or two on a couple of days. Wednesday will be the pick of the days, and Saturday will also be pretty good but will be partly cloudy with showers coming in the evening.”
