Today will see an end to Perth's extended hot spell after temperatures soared as high as 37 degrees earlier on in the week.
For the past ten days Perth has seen temperatures reach at least 27.7 degrees, making it the first November since 1973 that has had ten uninterrupted days of this kind of heat.
The ten day stretch included two extreme days with temperatures of 37.1 and 37.2 degrees. It has not been this hot this early on in November since 1997.
At present, the city is running four degrees above the current November average. Nights have also been warm, with minimum temperatures on Sunday only dropping to about 20 degrees, 6 degrees above the average.
Today will see an end to the trend as cooler air is filtered in by fresh southeasterly winds, keeping temperatures to their mid-20s.
Days will begin to warm up again later in the week as a low pressure trough approaches the region.
