Mourne Mountains Mountain weather forecast table
Confidence
High confidence in generally settled weather continuing.
This evening forecast
A dry evening with some sunshine, though this hazy with high level cloud spilling in from the west. Strong east to southeast gusts at times, generally 35-45mph but chance of the odd gust over 50mph possible. Feeling chilly at height with the strong winds.
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 and bright. Sunshine hazy at times.
