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 bring a risk of dehydration and heat stress, especially on long climbs, and high UV levels will require suitable protection from the sun. Windy conditions at times will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times

Weather

Dry and warm throughout the day. Largely prolonged sunny spells but the odd patch of cloud possible in the morning. Freshening southeast winds may be blustery in places.

Chance of cloud-free hill tops

90% or higher.

Low cloud and visibility

The odd patch of cloud possible around summit height over eastern aspects in the early morning. Otherwise clear summits and good visibilities with any cloud above summit height.

Ground conditions

No recent ground conditions report available.

Summit specific forecast

The Mourne Mountains are a granite mountain range in County Down in the southeast of Northern Ireland, is an area of outstanding natural beauty, and has been proposed as the first National Park in Northern Ireland.
