WA Seasonal Temperature Outlook: probabilities for July to September 2003, issued 17th June 2003

Warmer season in west and far north of WA

The Bureau's latest seasonal temperature outlook shows the odds are shifted in favour of warmer than average daytime temperatures in the north and west of the country.

For the July to September period, the chances of above average seasonal daytime temperatures are between 60 and 70% in the west and far north of WA. The WA outlook probabilities are mainly the result of higher than average temperatures in the Indian Ocean.

So with climate patterns like the current, about 6 to 7 seasons out of every 10 are expected to be warmer than average across the west and north of the State, with about 3 to 4 out of 10 being cooler. In remaining parts of WA the chances of above average seasonal temperatures are between 50 and 60%. The Bureau's July to September maximum temperature outlooks have moderate reliability over most of WA (see background information).

Warmer than average nights are also favoured over large parts of the country. The chances of above average seasonal minimum temperatures are between 60 and 80% across the southern half of WA, and between 50 and 60% over the northern half of the State. Minimum temperature outlooks for the season have moderate to high reliability over the southwestern half of WA, but low levels of skill in the north of the State.
