Perth is on track to experience its warmest Christmas morning in more than 110 years this Wednesday, with a blistering heatwave set to engulf the city and much of Western Australia.
A Century-Old Record Set to Fall
The Bureau of Meteorology forecasts an overnight minimum temperature of 26 degrees Celsius at 6am on Christmas Day. Senior meteorologist Robert Lawry confirmed this would break a long-standing record. "That would be a record... the last time it happened was in 1915," Mr Lawry stated. The mercury is then predicted to climb rapidly, reaching 36C by 10am and peaking at a scorching 41C by 2pm.
While a 41C maximum would be Perth's hottest Christmas Day since 2021, the exceptionally high minimum temperature is the standout feature. For context, Perth's all-time hottest night minimum sits at 29.3C, recorded in February of both 1898 and 1933. The BoM also warned that a cooling sea breeze is unlikely, meaning temperatures will remain well above 30C well into the evening.
West Australians Adapt with Seafood and Safety Precautions
In anticipation of the oppressive heat, West Australians are planning cool Christmas feasts. Shoppers flocked to Kailis Brothers' annual 36-hour Christmas Seafood Marathon in Leederville from early Tuesday, stocking eskies with fresh prawns, fish, and crayfish.
Owner Matt Kailis, whose family business is celebrating its 100th year of serving WA families, said the event holds special meaning. "Christmas is a time where families come together, and it feels really special to be a part of that tradition," he remarked. He expected to sell roughly 12.5 tonnes of seafood during the non-stop trade from 6am Tuesday to 6pm Christmas Eve.
Former WA treasurer Ben Wyatt, a return customer, highlighted the tradition. "It is very much a tradition, I do a whole fish every year - this year it’s a red emperor," he said, noting the preference for seafood in warm weather.
Authorities Issue Stern Warnings Amid Extreme Conditions
The forecast heat has prompted serious warnings from multiple authorities. Meteorologist Robert Lawry urged the public to "Hydrate, stay out of the sun, and take those extra precautions."
The Department of Fire and Emergency Services (DFES) is on high alert, with extreme fire danger warnings issued for a long list of regional shires and total fire bans in place for 18 local government areas. Deputy commissioner Craig Waters said DFES was more prepared than ever, having bolstered its aerial fleet to a record 38 aircraft, including two additional Black Hawk helicopters. However, he cited firefighter fatigue as a major concern after a busy start to summer.
WA Health's executive director of environmental health, Jane Cook, warned that food-borne bacteria thrive in the heat. She reminded people to follow food safety rules: clean, separate, cook, and chill.
With tens of thousands of boaties expected on the water, Water Police also stressed marine safety. DFES assistant director Mark Eatts emphasised one simple step: "While you’re out on the water, I strongly recommend you wear your life jacket." His warning followed recent rescues, including four people whose boat capsized on Monday evening.
The heatwave is widespread, with Geraldton expecting a top of 43C on Christmas Day. As Perth prepares for a historic and sweltering holiday, the message from all officials is clear: celebrate, but prioritise safety in the extreme conditions.
