Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
High confidence for changeable weather with drier spells interspersed between periods of more unsettled weather.
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.
Strong Sunlight
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Mountain weather forecast
Cloudy with outbreaks of rain in the morning, turning drier and brighter through the afternoon and evening.

Additional weather information
Met Office Aberdeen meteorologist's view
Feeling unseasonably cold at height, particularly under extensive cloud and fresh to strong summits winds, meaning that suitable clothing is required.
Weather
Extensive cloud through the morning, especially towards Lochaber, Moidart and the Nevis Ranges with outbreaks of rain or drizzle; drier and clearer spells developing towards noon for the Trossachs and Arran. The cloud lifting and breaking through the afternoon and evening to allow for some brightness, with some clear spells for a time before further cloud and rain spread in to the west coast just before midnight.
Chance of cloud-free hill tops
30% or less in the morning, the best chances in the south. Rising to 60% in the middle of the day, and 75% in the evening, the best chances in the south.
Low cloud and visibility
Extensive cloud down to 500-600m in the morning with moderate or poor visibilities in rain, drizzle or hill fog. This cloud lifting generally to around 800m through the afternoon with some breaks developing into the evening.
