Additional weather information
Meteorologist's view
Despite some cloud cover UV-levels will remain high, so appropriate sun-protection is recommended.
Weather
Mostly cloudy in the morning but with some brightness coming through the cloud at times particularly for the island ranges. Staying predominantly dry but the cloud may be thick enough to allow the very odd spot of light rain over northern ranges in mid-morning. Dry and bright through the afternoon and evening with some sunny spells breaking through.
Chance of cloud-free hill tops
50% at first, best chances over isles. Rising to 90% or higher by midday.
Low cloud and visibility
Quite extensive areas of cloud down to 300-500m in the morning, these gradually lifting and breaking through the morning. In the afternoon and evening summits will be largely clear with good or excellent visibilities and the cloud layer lying well above the summits.
Ground conditions
No recent ground conditions report available.
