Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
The main uncertainty in the forecast relates to the amount of cloud across the hills on Saturday morning and for the occurrence of any showers later. Good confidence for several dry, settled days from Sunday.
This evening forecast
A few passing showers this evening, perhaps briefly heavy. Otherwise, some late sunshine but tending to become cloudier. Light southwest 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
Overcast and rather dull, becoming brighter with sunshine through afternoon.
