Australian temperature forecast verification data are analysed with a view to establishing the existence or otherwise of trends in the skill displayed by the predictions. The data examined are for late afternoon forecasts of the next day's maximum and minimum temperatures issued to the public of the six Australian State capitals over the period 1964 to 1979 inclusive. It is concluded that the skill displayed by these predictions increased, on the average, over the period under consideration.
