Mountain weather
Northwest Highlands Mountain weather forecast table
Confidence
High confidence in the changeable and rather unsettled conditions during the next 5 days. Some uncertainty on details in the outlook period.
This evening forecast
Turning overcast with misty low cloud and drizzle pushing in from the west. Gales or severe gales on summits
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
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.
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
Rather cloudy with outbreaks of rain or showers. Windy.

Additional weather information

Notable wind chill on summits. Gusts of 30-40mph at height will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times.
Weather
A cloudy morning with outbreaks of rain, perhaps heavy at times. Rain turning showery into the afternoon with some brighter spells but still a good deal of cloud around.
Chance of cloud-free hill tops
20% rising to 50%.
Low cloud and visibility
Cloud bases down to 600-700m at first in the morning. Bases then rising up to around 800-900m in the afternoon with a few breaks in the low cloud at times. Visibility will be good below cloud bases but occasionally deteriorating to a few kilometres in rain or showers.
