Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
High confidence for rain late Wednesday into Thursday then mostly dry until Saturday. Low confidence for detail Sunday when showers possible.
This evening forecast
Overcast with rain in the evening becoming dry from late evening. Light southwest summit 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
A dry and bright day with light summit winds.
