Mountain weather
Northwest Highlands Mountain weather forecast table
Confidence
High confidence for unsettled weather and strong southeast winds. Low confidence in daily cloud and rain or summit snow details.
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.
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 morning, some rain. Brighter afternoon. Strengthening winds. Bitterly cold.

Additional weather information
Met Office Aberdeen meteorologist's view
Note the strengthening winds through the day, with gusts over 50mph giving very difficult walking conditions with progress highly impeded and a significant risk of being blown over. There will still be icy surfaces and lying snow at height so keep up to date with the latest avalanche forecast from Scottish Avalanche Information Service (SAIS). Feeling bitterly cold at height so suitable clothing is advised.
Weather
Quite cloudy by dawn with outbreaks of rain spreading north mainly affecting southern ranges such as Knoydart, Skye and Glen Shiel. Becoming dry with bright or sunny spells as this cloud clears north from late morning. Turning cloudier again from the south through the evening with some further patchy light rain or drizzle. Strengthening southeast winds through the day.
Chance of cloud-free hill tops
50% around dawn, rising to 80% or higher in afternoon. Falling to 40% in evening. Best chances in the north.
Low cloud and visibility
Areas of cloud around 500-700m in the morning and visibilities falling moderate in outbreaks of rain. Summits largely clear through the afternoon but still some patches of low cloud below 300-500m. Cloud down to 500-700m becomes more extensive through the evening in the south, remaining well broken in the north.
