WA Seasonal Temperature Outlook: probabilities for August to October 2003, issued 16th July 2003

Increased warmth favoured in WA during late winter/mid-spring

The Bureau's latest seasonal temperature outlook shows generally large swings towards warmer than average daytime and night-time temperatures over much of country for the late winter to mid-spring period.

For the August to October period, the chances of above average seasonal daytime temperatures are between 60 and 70% in the northern half of Western Australia, rising to 70 to 80% in the southern half of the State. The overall pattern of probabilities has mainly resulted from a warmer than average Indian Ocean.

So with climate patterns like the current, about 7 seasons out of every 10 are expected to be warmer than average over WA, with about 3 out of 10 being cooler. The Bureau's August to October maximum temperature outlooks have generally moderate reliability over the southern two-thirds of WA (see background information).

Warmer than average nights are also favoured over Western Australia. The chances of above average seasonal minimum temperatures are mainly between 60 and 80% across WA and minimum temperature outlooks for the season have moderate to high reliability over the south of the State.
