Australia: Heatwave spreading to NSW

Some of the heatwave conditions being experienced in Western Australia will travel across inland South Australia and into western New South Wales and northern Victoria.

On Monday temperatures have been reaching the mid forties over WA, peaking at 46.5 degrees at Roebourne Airport and 46.4 degrees at Marble Bar in the northwest and 44.8 degrees at Salmon Gums on Monday and its only going to get hotter. 

Parts of the Pilbara and Gascoyne area are likely to heat up to the high forties later this week with some places entering a heatwave with temperatures averaging as high as 37 degrees for three days and nights.

A heatwave is defined as staying more than five degrees hotter than average for at least three days running, day and night.

Remnants of this heat is gradually filtering across northern parts of SA and into western NSW and northwestern Victoria.

Whilst it won’t get nearly as hot for as long some areas, including Wudinna, Hawker, Loxton, Broken Hill, Ivanhoe, Balranald, Mildura and Ouyen will still endure a heatwave. By early next week these centres will average 30-to-34 degrees for three days and nights, six-to-eight degrees hotter than average.

Clear skies and a lack of strong cold fronts for the past few weeks have allowed the heat to build well above average over northern WA and a few weak fronts are now helping to drag some of the heat to southeastern Australia.

Adelaide reached the high thirties late last week and will get similarly hot later this week, however, cooling relief will occur most nights.
