Mourne Mountains Mountain weather forecast table
Confidence
High confidence a period of sunny spells and the odd heavy shower at times, looking cloudier Thursday and Friday, lower confidence for exact day to day details.
This evening forecast
Dry with good clear spells and the odd patch of cloud around 1000m. Brisk east or southeasterly 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
Mainly dry and bright, but the odd shower in the afternoon, and the chance of patchy low cloud returning in the evening.
