Perth could get more rain this weekend than it has received in the past three months when the first serious cold front of autumn hits south-west WA.

The Bureau of Meteorology (BOM) is predicting 10 millimetres a day could fall in Perth on Saturday and Sunday.

"It has certainly got the potential to be the first significant frontal system of the season," forecaster Gianni Colangelo said.

"If it does bring with it a decent amount of strength, it can certainly drop in the order of 10mm or even more in the Perth region."

However, the metropolitan area is expected to escape the heaviest falls - which are forecast to hit areas between Mandurah and Walpole.

"It's entirely dependant on how the system structures itself as it approaches," Mr Colangelo said.

"But you could easily get into the 20mm or higher in certain locations."

Downpour to end dry spell

The front is expected to reach the south-west corner of the state about midnight on Friday and hit Perth mid-Saturday.

Strong winds are also possible, but BOM will decide later in the week whether to issue a warning.

It has been a dry month for Perth so far, with the gauge collecting just 0.6 millimetres of rain - well short of the April average of 36.3mm.

The city's last significant rainfall was on January 16, when a massive 96.2mm was recorded in the wake of Cyclone Joyce.

Since then, Perth has received a total of just 6.2mm of rain.

Perth's forecast:

  • Wednesday: 23C, shower or two, clearing
  • Thursday: 21, cloudy
  • Friday: 22, possible shower
  • Saturday: 22, showers
  • Sunday: 21, shower or two
