Mountain weather
North Grampian Mountain weather forecast table
Confidence
High confidence in the slack pressure pattern dominating the next 5 days, however this brings some uncertainty on cloud detail, as well as extent of any showers on Sunday and Monday.
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
Misty low cloud lifting in the morning, otherwise dry, sunny spells. Low cloud returning in the evening.

Additional weather information
Met Office Aberdeen meteorologist's view
A chillier day than Friday, note the sub zero wind chill on summits early and late in the day.
Weather
Patchy low cloud and mist drifting in from the North Sea will lift and break up through the morning leaving it dry with sunny spells for much of the day. Best of the sunshine in the southwest for the likes of Creag Meagaidh and Ben Alder. Cloud will increase again from the northeast towards the evening bringing risk of hill fog for the Cairngorms.
Chance of cloud-free hill tops
70%, best chances in the southwest. Decreasing to 30% from late afternoon for the Cairngorms.
Low cloud and visibility
Occasional poor visibility in areas of misty low cloud below 900m at first in the morning, especially across northeastern areas, but largely clear on the highest tops. This low cloud will break up and lift through the morning and afternoon, before cloud bases drop down to 600-800m in the evening for the Cairngorms.
