Mountain hazards

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.

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

Hill fog and light showers mainly in the morning, brighter afternoon. Strong summit winds moderating.

Additional weather information

Meteorologist's view

Mod-High UV levels despite occasional cloud cover, suitable protection advised. Feeling chilly in the wind, note the sub zero wind chill on highest summits.

Weather

A few light scattered showers and areas of hill fog overnight and first thing in the morning. Turning mainly dry into the afternoon with some brighter spells developing, the odd light shower still not to be ruled out. Fresh to strong winds in the early hours, moderating during the morning.

Chance of cloud-free hill tops

40% rising to 80%

Low cloud and visibility

Cloud bases around 800m at first in the morning, these breaking up and lifting to 1200m or above in the afternoon. Visibility below cloud bases will be good but with brief deteriorations in light showers.

Ground conditions

No recent ground conditions report available.
