A strong area of high pressure has moved south of Western Australia this week, promoting a warm offshore flow for much of the state.
This flow brought unseasonably warm air from the interior of Australia to the west coast of Western Australia, including the capital city of Perth.
The heat wave began on Tuesday as temperatures climb to 32 C (90 F), in Perth. The mercury hit 33 C (92 F) on Wednesday.
The heat continued to build on Thursday as temperatures reached 35 C (95 F) for several hours.
By Friday, the high temperature reached 38 C (100 F), making it the hottest day since February, and is just a taste of what is come the next several days.
No relief is expected through at least early next week as temperatures will climb to near 38 C (100 F) each day through Monday across the Perth metropolitan region.
A weak cold front will approach the region during the middle of next week and will bring some relief after a week of sweltering heat.
A heat wave of this duration is very unusual in the first half of December; however, there was a seven-day heat wave that took place during the final seven days of December 2012.
