Months ahead

Long-range forecasting

Long-range forecasts provide information on how weather, averaged over the next few months, is expected to vary from normal. Long-range forecasts are indications of an overall picture, as it is impossible to forecast individual events so far ahead; the short-range forecasts are where the details begin to appear.

Long-range forecasts have global coverage and are used in areas like Africa to help plan for year-to-year variability in rainy seasons.
