Welcome to the Mountain Weather Information Service

MWIS currently produce forecasts for 8 different mountain areas of the UK as an aid to mountain safety.

Forecasts are produced manually using information from a range of forecast models and forecasters knowledge of mountain weather. New forecasts, for the next three days are produced by 4:30pm daily, normally earlier in the winter, and amended as necessary.

The production of the Scottish forecasts is fully funded by the Scottish Government through sportscotland with the support of The Mountaineering Council of Scotland.
