"Seasonal forecasting:
Seasonal forecasting is a developing area of meteorology and, although these forecasts are not as accurate as our short-term forecasts, they do demonstrate some skill in predicting what may happen for a season (a three-month period) ahead.
The forecasts provide an estimation of broad trends in temperature and rainfall and will normally be expressed in probabilistic terms, with the more likely outcome highlighted. Information contained in these forecasts can allow business to plan ahead for weather that is forecast to be different from normal.
