Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
High confidence in generally unsettled weather, but low confidence in developments from Tuesday onwards. Please note we are aware of an issue affecting forecast wind speeds and gusts for higher-elevation sites (typically above 500m) displayed on the Met Office website and app. The winds shown here in our Mountain Area Forecasts are not affected by this. Our teams are actively working to correct the issue and updates will be deployed as soon as possible.
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.
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.
Mountain weather forecast
Cloudy with showery rain. Cold.

Additional weather information
Met Office Aberdeen meteorologist's view
Windy conditions in the morning will make for fairly arduous walking on exposed terrain with buffeting of clothing, note the easing winds through the day. Balance may be affected at times. Feeling cold at height so suitable clothing is advised. Still lying snow around at height so keep up to date with the latest avalanche forecast from the Scottish Avalanche Information Service (SAIS).
Weather
Cloudy throughout the day with showery outbreaks of rain, especially in the early morning and early afternoon with some drier slots between, these showers wintry above around 900m. Feeling cold at height.
Chance of cloud-free hill tops
30%, best chances in evening
Low cloud and visibility
Quite widespread cloud down to 400-600m with visibilities falling moderate or poor in hill fog or showers. Cloud more broken in late morning and again in evening allowing some temporary clear spells.
