The west of the country is set to experience the hottest Christmas period since records started over 100 years ago.
Temperatures across parts of Western Australia, from Shark Bay down to Walpole, are forecast to reach 42C across Christmas and Boxing Day, according to the Bureau of Meteorology.
The heatwave is being driven by a high-pressure ridge pushing a west coast trough offshore meaning that sea breezes, which would normally offset the hot temperatures, will be weak.
“Hot conditions and some gusty easterly winds will increase the fire dangers through the Perth area and all the way down to the south-west forest areas as well,” BoM WA state manager James Ashley said.
“We’re expecting very high or high to severe fire danger ratings.”
There is also an increasing chance of monsoonal weather for Australia’s top end from this weekend as Christmas festivities get underway.
