Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
Fair conditions on Tuesday but unsettled for the rest of the forecast period with periods of rain and stronger winds. Lower confidence in forecast timings and details towards the weekend so best to keep updated with the latest forecast.
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.
Mountain weather forecast
Mainly dry and bright, fresh or strong northwesterly winds will make it feel chilly.
