Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
High confidence in the dry, settled and mostly dry conditions prevailing for the next 5 days, but some uncertainty on the extent of any afternoon showers this weekend.
This evening forecast
Clear and dry with light winds. Isolated mist and fog patches forming in valleys overnight.
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
Hazy sunny periods and mainly dry.

Additional weather information
Meteorologist's view
Note moderate or high UV levels despite occasionally hazy or cloudy skies, suitable protection is advised.
Weather
Any early most or fog in valleys quickly clearing. Otherwise a dry and bright morning with some hazy sunny periods as high cloud spreads across the sky. Cloud will tend to bubble up through the day and bring just a low risk of the odd shower late afternoon or evening.
Chance of cloud-free hill tops
100%
Low cloud and visibility
A risk of poor visibility in any low level mist or fog patches at first. Otherwise cloud bases will be above summits and visibility will be very good.
