Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
Low for extent of cloud breaks on Sunday and Monday, otherwise high for a lot of dry and settled weather into next week
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
Cloudy and mostly dry, strong southwesterly summit winds
