Parts of Western Australia and South Australia have just had their warmest day since winter and parts of New South Wales and Queensland are about to.

Normally this would happen in late August or September but an unusually warm airmass formed over WA on the weekend and it is being drawn across the south of the country by northwesterly winds.

We are still in the first week of August and temperatures are reaching the mid to high 20s, four-to-eight degrees above the August average.

Sunday was the warmest day since May for much of western WA, including Bunbury (22 degrees), Esperance (25), Kalgoorlie (26), Morawa (27) and Meekatharra (27).

Monday was the warmest day since May for some places in the west of SA, including Nullarbor (28 degrees), Ceduna (26), Wudinna (24) and Whyalla (24).

Tuesday will be the turn for parts of central Australia and also parts of NSW and Queensland.

Parts of northern SA and the area between Sydney and the Gold Coast can expect their warmest day for winter so far. Places which should achieve this are Penrith, Gosford, Newcastle, Taree, Port Macquarie, Coffs Harbour and Coolangatta.

Unseasonably warm northwesterlies will give way to colder southwesterlies on Wednesday and Thursday as a cold front crosses the region. The front will lower temperatures by as much as seven or eight degrees before it warms up again in time for the weekend.
