Confidence
High confidence for settled conditions, slightly lower confidence in cloud extent.
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.
Mountain weather forecast
Dry with prolonged sunshine.

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.
The Mourne Mountains include the highest mountains in Northern Ireland; the highest of these is Slieve Donard standing at 850 metres at the northeastern edge of the Mournes, overlooking Newcastle and Dundrum Bay. At the summit of Slieve Donard there is a cairn and a small stone tower, which is part of the Mourne Wall, which passes over the mountain’s southern and western shoulders.
The Mourne Wall is a 35 kilometre dry stone wall that crosses fifteen summits, constructed between 1904 and 1922 by the Belfast Water Commissioners to define and enclose the catchment area for the newly constructed Silent Valley Reservoir.v
