Mourne Mountains Mountain weather forecast table
Confidence
High confidence in generally unsettled weather, but low confidence in developments from Tuesday onwards. Please note we are aware of an issue affecting forecast wind speeds and gusts for higher-elevation sites (typically above 500m) displayed on the Met Office website and app. The winds shown here in our Mountain Area Forecasts are not affected by this. Our teams are actively working to correct the issue and updates will be deployed as soon as possible
This evening forecast
Cloudy down to 300-500m and perhaps the odd spot of light rain at first. Becoming clearer through the evening, but this may allow some mist or fog patches to form in valleys. Light winds. Feeling cold at height.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
Severe Chill Effect
Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.
Poor Visibility
Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.
Mountain weather forecast
Rain in morning. Dry, bright afternoon. Cold.

Additional weather information
Meteorologist's view
Note the windy conditions around the middle of the day, making for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times. Feeling cold at height so suitable clothing required. Much of the ground may still be saturated after recent rain.
Weather
Cloudy with a few light showers possible in the early hours. Band of rain spreads east from around dawn, this rain heavy at times, and clearing east just after midday. Then the afternoon dry and increasingly bright, staying dry and largely clear through the evening.
Chance of cloud-free hill tops
Little chance in morning, rising to 90% or higher in afternoon.
Low cloud and visibility
Areas of cloud down to around 500m in the early hours, becoming widespread down to 300-500m from dawn with visibilities falling poor in hill fog or rain. Then cloud clearing through the afternoon leaving summits clear and good visibilities.
