Heavy showers disrupted peak hour in Perth Tuesday morning and made this the second wettest June in nine years for Bunbury.

Parts of Perth were soaked with 5mm of rain in just 10 minutes, with the CBD picking up 7mm in half an hour. The most rain fell south of Perth though, where Waroona collected 40mm and Bunbury 34mm.

Yesterday morning’s wet weather brought Bunbury’s running total to 157mm so far this June, 10mm more than they usually see in the whole month. After only 19 days, this is now their second wettest June since 2003.

A strong cold front triggered the wet weather as it swept over the nation’s southwest.

The front also generated strong winds near Perth, which gusted up to 83 km/h at Rottnest Island just before 7am.

A spell of drier weather will follow from Thursday and across the weekend as a high pressure ridge extends over southern WA. The next chance of rain won’t come until early next week for most of the region.

If Bunbury records another 24mm by the end of the month, this will be the second wettest June of the last 12 years. It will need another 84mm to go down as the wettest June on record.

Looking ahead for Perth, clearer skies and light winds will combine with a cool air mass later this week to produce a run of cold nights. The city has a chance to chill below five degrees each night from today to Saturday, as much as five degrees below average for June.
