Tas Seasonal Temperature Outlook: probabilities for Summer 2003/2004, issued 14th November 2003

Neutral odds for a warmer than average summer in Tasmania

The Bureau's summer temperature outlook shows the chances of above average daytime temperatures are close to 50:50 across Tasmania. This outlook is the result of the combined effect of warmer than average temperatures in the tropical Pacific Ocean, and a strong cooling trend in the Indian Ocean.

For the December to February period, the chances of above average seasonal daytime temperatures range from 40 to 50% across Tasmania. So with climate patterns like the current, about 5 seasons out of every 10 are expected to be warmer than average across Tasmania, with about 5 out of 10 being cooler.

Outlook confidence is related to the influence of Pacific and Indian Ocean temperatures on seasonal temperatures. During summer, history shows this influence on maximum temperatures to be moderate over much of Tasmania, except for a small area on the west coast where this relationship is weak (see background information).

The summer minimum temperature outlook is also neutral across Tasmania with probabilities in the 45 to 55% range. This outlook pattern is mostly due to above average temperatures in the Pacific Ocean.

History shows the oceans' influence on summer minimum temperatures to be moderate across Tasmania.
