Mountain-specific context
Summit wind, cloud around the tops and changes through the day can matter more than conditions in the nearest town. Separate hill-weather and Views scores help make those differences clear.
Built for days in the hills.
I'm Simon Grogan, a mountain leader and software developer, and the person behind Mountain Weather.
My interest in weather starts with the landscape: how a ridge changes the wind, why cloud clings to a hillside, and why a summit can feel so different from the valley below.
Mountain leadership brings weather, terrain and people together. The same conditions can mean very different things for different groups, routes and plans. That perspective is at the heart of this project.
Mountain Weather combines my practical mountain background with software development and a curiosity about how weather works in the hills. The aim is to help people arrive better prepared and make more informed decisions, supporting safer, more enjoyable days out.

Evidence, not certainty
The method draws on terrain research and checks against observations. We publish what has been tested and what remains exploratory. Use the service alongside official forecasts, warnings and the conditions you find on the hill.
How the site is funded
