Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
High for cold and bright conditions with wintry showers during the weekend.
This evening forecast
The evening will continue dry with long clear periods and gale force easterly summit winds.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
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.
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
A bitterly cold but dry and sunny day with gale force easterly winds at height gradually easing down from the morning.
