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.

As always, please continue to give us feedback about what you think of our website, service and future development plans.

Clocks have gone back!

As usual we will aim to issue forecasts at about 1pm during the winter (we cannot always guarantee this). We are able to do this because there is more time to consider the several weather prediction models run from observations up to 0600 GMT, and with shorter daylight, often less variability in weather to incorporate (although this compensated somewhat by more lengthy comments require during severe conditions.

Planning video, updated Friday 20th November : 
Cold weekend, then milder & frequent upland gales

We are trialling forecast videos concentrating on the outlook period. They do take time to prepare, will be updated two or three times a week: generally around Tuesday, when there is some clarity on the weekend to come, and over the weekend with a look forward to the coming week.

As with all our forecasts, please give us feedback.
