Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
High confidence in continuing unsettled weather with showers or longer spells of rain at times and occasionally strong winds.
This evening forecast
The odd shower at first will soon clear northeast leaving an increasingly dry and clear evening. Feeling bitterly cold on the summits with strong southerly winds, gusting around 50-60mph or a little higher over the highest summits.
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.
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.
Thunderstorms
Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.
Mountain weather forecast
Rain in the morning. Scattered showers follow, wintry on summits. Feeling bitterly cold. Strong winds.

Additional weather information
Met Office Aberdeen meteorologist's view
Feeling bitterly cold. Gusts of 45-55mph will give difficult walking conditions with a risk of being blown off balance. Navigation could be challenging with energy output significantly increased when walking into the wind.
Weather
Clear skies at first, but soon clouding over through the early hours as rain spreads north, heavy at times with a small chance of lightning. This clears away in early afternoon allowing for some bright spells and scattered showers, these turning wintry above 800-900m. Showers become frequent through the evening.
Chance of cloud-free hill tops
Falling to 25% through the early hours, rising to 40% through the afternoon.
Low cloud and visibility
Often clear skies at first will cloud over in the early hours, cloud becoming fairly extensive down to 600-800m and visibilities dropping poor in heavy rain and hill fog. Summits becoming often clear from early afternoon onwards as rain clears away northeast. Thereafter some clearer, drier spells at times, but summits often shrouded and visibilities falling poor while showers pass through.
Mountain weather information
Weather
Frequent showers feed in from the west, wintry above 900-1000m. These become quite isolated for a time in the afternoon before more widespread rain, preceded by sleet or snow on the highest peaks, spreads east through the evening.
Chance of cloud-free hill tops
25%, rising 60% for a time in the afternoon, falling to little chance in evening.
Maximum wind speed expected
Southwesterly, gusting 40-50mph over the highest summits.
Temperature
- At 800m Plus 0 rising to plus 2 Celsius.
- Glen Plus 6 rising to plus 9 Celsius.
- Freezing level 900m rising to 1100m by day, then above summits in evening.
Low cloud and visibility
Frequent showers from the west in the morning will bring quite extensive areas of cloud down to 700-900m and visibilities falling poor. Some clearer spells develop through the afternoon, before widespread cloud down to 700-900m spreads east with poor visibilities in rain and hill fog.
