Clear skies to give way to rainy weather this week

Sydney may see some long overdue rain this week as the warm weekend weather gives way to rain, wind and cooler temperatures for the last week of August.

The city enjoyed balmy conditions on Saturday, with a top temperature of 25.5 in the city, while it reached 25.6 at Sydney Airport at 3.20pm and 24.6 at Bankstown at 2.30pm.

The blue skies continued on Sunday, which reached 21.5 degrees in the city at 11.30am.

Surfers took advantage of the combination of sunny skies and significant swell that developed as a result of last week's combined deep low and high-pressure system.

But winter refuses to go away with a whimper.

Bureau of Meteorology forecaster Bimal KC said showers should arrive on Monday and Tuesday, with temperatures forecast to drop to a maximum of 16 degrees on Monday and 17 on Tuesday.

"Another front coming in from the west on Wednesday will add a little bit of momentum to the existing trough in the north-east," Mr KC said.

Weatherzone meteorologist Graeme Brittain said on Sunday conditions would become more unsettled in the week to come.

Grey skies and rain are forecast for most of the week.

"There's a low-pressure trough that's going to deepen along the coast of NSW, directing moisture on and to the east of the ranges, including Sydney," Mr Brittain said.

Mr Brittain said after daily rainfalls of between 10 and 15 millimetres in coastal parts of Sydney earlier in the week, downpours could reach more than 30mm along the South Coast.

Accompanying the rain, "there could be some gusty winds for Sydney," he said.

Overnight minimum temperatures for the next week are expected to range between 9 and 11 degrees.

The Bureau of Meteorology predicts a high temperature of 21 degrees on Wednesday before it drops again to 15 degrees on Thursday.
