Wet start to Perth winter no guarantee of reaching city's rainfall average

After the wettest start to winter in 13 years, a string of gloriously sunny days is threatening to derail Perth's chances of reaching its June rainfall average, and now it all hinges on one day.

Wednesday is forecast to be the only wet day for the rest of the month.

"We're expecting a cold front to move through the metropolitan area on Wednesday," Bureau of Meteorology forecaster Mark Paull said.

"We're expecting rainfall figures somewhere between 10 and 20 millimetres, fairly widespread, maybe some isolated falls that get up to around 25 millimetres."

The city's rainfall total for the month so far is 98.2mm, which means Perth needs another 26.2mm to get to the June average of 124.4 mm.

Perth has not reached its June average since 2012, with last year's rainfall total for the month just 88mm.

Mercury set to dip

Wednesday's cold front will move through south-western parts of the state, with falls expected to be lighter inland.

"As it heads into the northern and eastern agricultural areas it'll weaken, we'll probably see falls of around the 1–5 millimetre mark," Mr Paull said.

You may want to get the extra blankets out in the lead-up to the weekend, with the mercury expected to dip to just 3 degrees Celsius overnight on Friday.

That is due to a high-pressure ridge which will move in swiftly after the cold front, bringing sunny days, cold nights and light winds.

Perth's forecast:
Tuesday: Cloudy. Max 20. Min 8
Wednesday: Showers. Max 19. Min 11
Thursday: Partly Cloudy. Max 17. Min 6
Friday: Sunny Max 17. Min 3
Saturday: Sunny. Max 19. Min 5
Sunday: Mostly sunny. Max 21. Min 8
