Mourne Mountains Mountain weather forecast table
Confidence
High confidence for largely unsettled weather continuing. Low confidence for details on Saturday, and for exact timings from Monday onwards.
This evening forecast
Widespread cloud down to 300m and persistent and at times heavy rain through the evening, snow above 700m. Feeling bitterly cold in strong easterly winds, 40-50mph.
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. Mostly dry morning, showery rain afternoon. Chilly.

Additional weather information
Meteorologist's view
Feeling cold at height under quite persistent low cloud so suitable clothing is advised. The ground will likely still be saturated after recent rain so care should be taken and suitable footwear worn. Less windy than recent days but still gusty with buffeting of clothing at times.
Weather
Cloud with a few showery outbreaks of rain and strong easterly winds in the early morning. Becoming dry by dawn but staying cloudy, as winds become light to moderate. Showery outbreaks of rain feed in again through the afternoon and evening.
Chance of cloud-free hill tops
20% or less - best chances around midday
Low cloud and visibility
Quite widespread cloud down to 300-500m throughout the day with associated poor visibilities in hill fog and outbreaks of rain. Small chance of a few temporary clearer breaks around midday and early afternoon.
