Mountain weather
Mourne Mountains Mountain weather forecast table
Confidence
High confidence in seeing generally unsettled weather, but low for details Tuesday, Wednesday and Friday.
This evening forecast
The odd spot of rain possible at first before this fully clears north, otherwise dry through the evening. Widespread cloud down to around 300-500m and poor visibilities in hill fog. South to southeast winds around 30-40mph, gusting 50mph over the highest summits.
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.
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.

Additional weather information
Meteorologist's view
Gusts of 40-60mph or so will give difficult walking conditions with a risk of being blown off balance and energy output significantly increased when walking into the wind. Periods of low cloud will make navigation challenging at times. Feeling cold at height so suitable clothing is advised.
Weather
A cloudy but mostly dry day, though the very odd spot of light drizzle possible. Variable amounts of cloud and a few bright spells possible. Feeling a bit milder than Monday, but still cold at height with strong southerly winds.
Chance of cloud-free hill tops
60%.
Low cloud and visibility
Areas of cloud down to 400-600m coming and going at times, bringing occasionally poor visibilities in drizzle or hill fog. Good spells of clear summits and good visibilities between cloud banks.
