Finally, a mild week for southwest WA

After months of warmer than average temperatures, southwest WA is seeing a colder than average week. 

The mild beginning to the week in the southwest has been caused by cooler southwesterly winds behind a cold front which marched across the state on Monday.  

This comes after a warm October, with the average maximum temperature of 26.2°C, nearly 5°C above average. 

While the southwest of the state is enjoying mild spring temperatures, the cooler airmass did not make its way to the north of the state. Severe heatwave conditions are occurring as a result in the south and north interior of the state in the coming days.

Daytime and nighttime temperatures dropped to around 2 to 3°C below average in the southwest from early Monday in response to this cooler airmass. 

Perth’s minimum temperature dropped to 12.2°C early Monday morning, with the maximum in the afternoon only reaching 21.9°C which is well below the November average of 24.6°C. 

The maximums will continue to be below average until Friday, meanwhile Thursday and Friday mornings will be chilly. 

The image below shows the maximum temperature contrast across the state on Tuesday afternoon.

Perth’s maximum temperature should reach: 

  • 22°C Tuesday 
  • 21°C Wednesday 
  • 22-23°C Thursday 
  • 24-25°C Friday 

The overnight temperature will plunge to around 9 to 10°C early Thursday morning, which is around 4°C below average. The minimum should be around 12-13°C later in the week before returning to the average of 14°C early Monday morning.  

Looking ahead, maximums will finally tend to above average from early next week and are expected to be hot this summer, with an increased risk of extreme heat.
