Mourne Mountains Mountain weather forecast table
Confidence
High confidence for unsettled weather with rain and strong winds at times, but low confidence for day to day details, especially from Monday.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
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.
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.
Mountain weather forecast
Cloudy, some rain. Chilly.

Windy conditions in the early morning will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times. Note that winds should ease through the day. Feeling cold at height so suitable clothing is advised. Widespread low cloud and hill fog so good navigation skills will be required.
