Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
Medium for cloud details. High for general developments.
This evening forecast
Rather cloudy. Some clearer spells. Moderate or fresh east or northeast winds at height.
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.
Mountain weather forecast
Early low cloud. Bright and sunny spells. Breezy over the summits.
