Additional weather information
Meteorologist's view
Widespread low cloud for much of the day will make for difficult navigation at times. Where the sun breaks out in the afternoon UV levels will be high so suitable protection is advised. Windy conditions through the morning will make for difficult walking conditions with a risk of being blown off balance and energy output significantly increased when walking into the wind.
Weather
Largely dry through the early hours and to start the day with some clear spells. Cloud and outbreaks of rain spread south during the morning, rain perhaps heavy at times. This clearing around mid-afternoon to leave dry weather and sunny spells. Cloud and outbreaks of light rain spread back east later in the evening. Strong west to southwest winds with summit gales in the morning, winds will ease through the afternoon.
Chance of cloud-free hill tops
75% first thing, falling to 20% or less during the morning. Rising to 90% or higher from mid-afternoon. Falling back to 20% or less during late evening.
Low cloud and visibility
Mostly clear summits in the early morning with only the odd patch of cloud possible around 400-600m. Widespread cloud down to 400-600m will spread south through the morning with visibilities falling moderate or poor in hill fog and outbreaks of rain. This clearing during the afternoon to leave summits clear and good visibilities. Widespread low cloud returning through late evening.
Ground conditions
No recent ground conditions report available.
