Mountain hazards

Mountain weather hazards

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

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

Variable cloud and bright spells, some light showers. Breezy.

Additional weather information

Meteorologist's view

Navigation will be tricky at times in hill fog and outbreaks of rain. Occasionally breezy conditions will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times.

Weather

A rather cloudy day with a few light showers, though with some bright spells developing at times in-between. Quite breezy.

Chance of cloud-free hill tops

50%.

Low cloud and visibility

By day some clear summits at times with cloud above the peaks, but cloud temporarily dropping to 600-800m and visibilities falling rapidly moderate or poor for a time as showers pass through.

Ground conditions

No recent ground conditions report available.
