NSW Seasonal Temperature Outlook: probabilities for November 2004 to January 2005, issued 19th October 2004

Above average temperatures favoured in NSW

There is a moderate shift in the odds towards above average maximum and minimum temperatures across New South Wales for the late spring to mid-summer quarter (Nov-Jan), the Bureau of Meteorology announced today.

The current pattern of outlook probabilities is mainly due to recent above average temperatures in the Pacific Ocean.

For the November to January period in NSW, the chances of above average maximum temperatures are between 60 and 70% (see map). So in years with ocean patterns like the current, about six or seven November to January periods out of ten are expected to be warmer than average across NSW, with about three or four out of ten being cooler.

Outlook confidence is related to the consistency of the influence of Pacific and Indian Ocean temperatures on seasonal temperatures. During November to January, history shows this influence on maximum temperatures to be moderately consistent across NSW (see background information).

Overnight temperatures also have an increased chance of being above normal across NSW for the late spring to mid-summer period, with the chances of above average minimum temperatures being between 60 and 70%.

History shows the oceans' influence on minimum temperatures during November to January to be moderately consistent over most of NSW.
