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.
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. 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, and some access roads and car parks may be flooded.
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.
