Mountain hazards

Mountain weather hazards

Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

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.
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 a few shower light showers, becoming brighter late morning, cloud and rain spreading east later.

Additional weather information

Meteorologist's view

Quite cool in brisk northwesterly winds which may be gusty around showers early in the day, notice freezing levels lowering to around the height of the higher munros during the morning, any showers may turn a touch wintery for a time. Summit gales later in the day with winds on the Cairngorm Plateau possibly gusting over 50mph.

Weather

A few showers overnight but a few clearer spells too. A lot of bright or sunny weather during the day but a few showers too, mostly moving through quite quickly. Clouding over later in the day as some light rain spreads in from the west during the evening, turning heavier later in the evening.

Chance of cloud-free hill tops

70% improving to 90%, patchy low cloud in association with showers early in the day.

Low cloud and visibility

Patches or areas of low cloud above 600m at times associated with showers during the morning, particularly on more exposed northern hills. Visibility likely to fall moderate in any heavier showers for a time. Any early mist or fog should clear steadily during the early morning.

Ground conditions

No recent ground conditions report available.
