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.

Additional weather information

Meteorologist's view

Warm temperatures - notably a few degrees higher than Monday - bring a risk of dehydration and heat stress, especially on long climbs. Despite some cloud cover UV-levels will remain high, so appropriate sun-protection is recommended.

Weather

A dry and bright day and a few degrees warmer than Monday. Plenty of prolonged bright or sunny spells, but high-level cloud will turn the sunshine hazy at times.

Chance of cloud-free hill tops

90% or higher.

Low cloud and visibility

Summits clear and good or excellent visibilities for the majority of the day.

Ground conditions

No recent ground conditions report available.
