Additional weather information
Meteorologist's view
Gusts to around 40mph on exposed terrain may make for fairly arduous walking with balance affected at times. Also note mod-high UV levels despite often cloudy or hazy skies, suitable protection is advised.
Weather
Outbreaks of occasionally heavy rain will clear quickly in the early hours. Then a rather cloudy morning with hill fog and the odd light shower. Cloud will gradually lift and break up through the afternoon to give some bright or hazy sunnier spells. Strong summit winds, perhaps the odd gale force gust.
Chance of cloud-free hill tops
20% rising to 70% in the afternoon.
Low cloud and visibility
Low cloud shrouding most tops above 700m in the morning, lifting to around 1000m or above during the afternoon. Visibility will be good below cloud bases, perhaps with brief deteriorations in any light showers.
Ground conditions
No recent ground conditions report available.
