Built for days in the hills.

I'm Simon Grogan, founder and lead developer of Mountain Weather, a Mountain Leader and member of the Royal Meteorological Society.

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.

My role is to bring that practical mountain perspective into the design and development of the service. Our aim is to help people arrive better prepared and make more informed decisions, supporting safer, more enjoyable days out.

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.

Cross-check forecasts before committing to a plan.
