Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
Generally high confidence in weather picture but slightly lower for shower detail Tuesday. Confidence reduces from Wednesday with the next low pressure system.
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
Mostly dry with bright or sunny spells. A few showers this evening.
