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 (See feedback below.)

Planning video, updated Sunday evening 22nd May: Week ahead outlook, thoughts for next weekend

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.

Feedback from users

Always good to get emails from users: we have had some positive comments from those who have looked at our videos, and a slightly less usual request from Canada!

Hi Guys, Loving the videos. Personally I think these would be a great addition to the service, very detailed and provide a great picture for the days ahead. If you decide too launch these going forward, in addition to the written forecasts, I think these would be a valuable asset. As long time MWIS user and mountaineer and hillwalker of over 30years experience, I would certainly value this addition to the service and watch the video service before every trip if you continue with them.

Keep up the great work guys.


And from Ottawa:

Totally unacceptable. We shall be over to hike the TGOC challenge from Torridon to Montrose beginning on may 13th. We absolutly insist that you change the weather to something much more agreeable. We would request minimums of 12 degrees and rising to 18 degrees during the days. We further request that you drain any saturated bogs and trails so that we do not get our delicate Canadian feet wet. In the event you fail to deliver such accommodating conditions we shall resort to over indulgence of Scotch and consumption of perhaps even some of your haggis.

We are excited at crossing Scotland come what may and thank you for your attention to the gods of the weather.

Dara, Liam, Brendan and Adam. TEAM CANADA 2016 TGOC Ottawa.
