Mourne Mountains Mountain weather forecast table
Confidence
High confidence at first, decreasing by Thursday with uncertainty on movement of the low and associated rain and wind.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
Mountain weather forecast
Dry and mainly sunny on Wednesday. Winds increasing through the day.
