Additional weather information
Meteorologist's view
Strong winds with summit gales in the morning will give difficult walking conditions with a risk of being blown off balance. Navigation could be challenging with energy output significantly increased when walking into the wind. Widespread low cloud in the morning will make for difficult navigation at times. Heavy rain in the early hours may leave some routes and watercourses saturated, suitable footwear should be taken. Where the sun breaks out in the afternoon UV levels will be high so suitable protection is advised.
Weather
Cloudy with occasionally heavy rain in the morning and gale-force summit winds. Rain turns more showery later through the morning with some brighter spells developing and winds beginning to ease. Mostly dry in the afternoon with some bright or sunny spells developing, just the small chance of the odd light shower. Low cloud returning from the west in the late evening with some outbreaks of light rain or drizzle.
Chance of cloud-free hill tops
Little chance early morning. Rising to 40% by midday, 70% by mid-afternoon. Falling back to 30% or less in late evening.
Low cloud and visibility
Widespread cloud down to 300-500m and visibilities falling poor in hill fog and occasionally heavy rain in the early morning. This gradually lifting and breaking up after dawn allowing for some clear spells to develop between showers, then summits often clear in the afternoon with cloud above all but the highest summits. Widespread low cloud feeds in from the west again in the late evening.
Ground conditions
No recent ground conditions report available.
