Weather and conditions
The UK mountain weather can change fast. A bit of knowledge about how to read a forecast saves a lot of misery — and occasionally, more than that.
Which forecast to use
Mountain Weather Information Service (MWIS) and the Met Office Mountain Forecast are both good. The BBC and general weather apps don't show wind chill or summit conditions accurately — use a mountain-specific forecast for anything above 600m.
Wind chill
A 5°C day with 30mph winds feels like -3°C. On exposed ridges, wind speeds are higher than in the valley. A temperature that seems fine at the trailhead can be dangerous on a summit. Check wind speed and direction, not just temperature.
Visibility
Cloud often sits on summits even when the valley is clear. Low visibility changes the difficulty of a route significantly — navigation becomes harder, it's easier to go off course, and it's harder for rescuers to find you if needed. Know your navigation skills honestly.
When to turn back
Before you go, decide on a turnaround point or conditions threshold — and stick to it. Most mountain accidents happen when people push through deteriorating conditions because they're close to the top. The summit isn't worth it.
Seasons
UK mountains can have full winter conditions from October to April, and freak snow at any time. Summer is no guarantee of safe conditions. The routes on this site note best seasons honestly — treat them as real information.
In an emergency
- Call 999 or 112 → ask for Police → then Mountain Rescue
- No signal? Text 999 — pre-register first: text "register" to 999
- Coastal routes: ask for Coastguard instead of Mountain Rescue
