Vic Seasonal Temperature Outlook: probabilities for October to December 2003, issued 16th September 2003

Warmer end to the year for Victoria

The Bureau's temperature outlook for the December quarter shows a large swing towards warmer than average daytime temperatures over Victoria.

For the October to December period, the chances of above average seasonal daytime temperatures are above 75% over almost the entire State. The overall pattern of probabilities is mainly the result of above average temperatures in the Indian Ocean.

So with climate patterns like the current, about 3 seasons out of every 4 are expected to be warmer than average across Victoria, with about 1 out of 4 being cooler.

Outlook confidence is related to the influence of Pacific and Indian Ocean temperatures on seasonal temperatures. During October to December, history shows this influence on maximum temperatures to be weak to moderate over Victoria (see background information).

Warmer than average nights are also favoured over most of northern and western Australia, but across Victoria the chances of above average seasonal minimum temperatures are between 50 and 55%.

History shows the oceans' influence on Oct-Dec minimum temperatures to be weak over much of Victoria becoming very weak in the northeast.
