Mountain hazards

Mountain weather hazards

Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

hazard Severe Chill Effect
Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.

hazard Poor Visibility
Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.

hazard Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.

Mountain weather forecast

Cloudy west coast, outbreaks of rain and hill snow. Drier, sunny spells in east. Strong to gale force winds.

Additional weather information

Met Office Aberdeen meteorologist's view

Poor visibility in hill fog will make for challenging navigation on the west coast. Note the strong winds on tops bringing a significant windchill.

Weather

Cloud and hill fog lingering on western coasts through much of daytime alongside outbreaks of rain, snow above 800m. Generally dry inland with the best of the sunnier spells across Eastern Ross and up to Caithness. Strong to gale force winds on tops. Turning widely dry with clear spells in the evening.

Chance of cloud-free hill tops

10% for The Cuillin, 70% for Ben Wyvis. Best chances in the afternoon. Increasing widely 80% in the evening.

Low cloud and visibility

Low cloud bases extensive on the west coast and lingering around 600-700m for much of daytime. Much clearer inland with just a few patches of summit cloud for a time. Becoming widely clearer in the evening.
