How the verdict works

  • Not today: gusts of 50 mph or more, wind chill of −10°C or below, or 10 mm or more of rain.
  • Not today also covers 5 cm or more of snow on the tops.
  • Think twice: gusts of 35 mph or more, wind chill of −3°C or below, 3 mm or more of rain, snow showers, freezing level below the summit, or the summit likely in cloud.
  • Go: none of the above. Still carry full hill kit.

Before you go

Mountain weather changes quickly, and the ridges around Cìr Mhòr and the A' Chìr ridge are serious scrambling in wind. Check the Mountain Weather Information Service, tell someone your route, and in an emergency call 999 and ask for Police, then Mountain Rescue.
