WA weather: Heatwave warning for parts of State as mercury tipped to climb past 40C

Parts of WA are set to sweat through a scorching first weekend of 2026 with temperatures expected to climb past 40C.

The Bureau of Meteorology has issued a heatwave warning for the Pilbara, Gascoyne, Goldfields, Eucla, North and South Interior and the Central Wheatbelt.

Harsh heat will hit those areas over the weekend and continue to creep up to the mid forties by the start of next week.

Meteorologist Angus Hines said sunshine is in store for most of WA, with severe conditions sweeping across large parts of the State.

“Temperatures will be about the mid thirties across the west coast and that will rise to about 40C for the Wheatbelt, Great Southern and parts of the interior,” he said.

“Very hot and sunny around the Pilbara, we see 40C temperatures through inland parts of the north as well.”

Kalgoorlie will swelter through a maximum of 41C on Saturday, with the mercury tipped to reach 43C on Sunday and 44C on Monday.

In the Pilbara, Karratha is forecast to reach 39C over the weekend, 41C and 43C is in store for Newman on Saturday and Sunday respectively and temperatures in Port Hedland will sit at 39C on both days.

The heat doesn’t plan on holding back in Northam and York, with maximums of 40C and 41C across the weekend.

Perth’s metro area is in for a more comfortable weekend with temperatures in the city to hover around the low thirties.
