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.

Warm and humid conditions bring a risk of dehydration and heat stress, especially on long hikes. Risk of sunburn despite occasionally hazy and cloudy skies, suitable protection is essential.

Weather

Bright but humid with intervals of warm hazy sunshine. Dry during much of the daytime, although the odd light shower can't be ruled out.

Chance of cloud-free hill tops

Low cloud and visibility

Very little if any low cloud on the hills and tops expected to be clear throughout. Visibility will be good but skies rather hazy.
