Confidence

High confidence in generally settled conditions over the next 5 days but lower confidence in the detail and timing around any light rain.

Mountain hazards

Mountain weather hazards

Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

Strong Sunlight
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.

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 at times in the morning with cloud clearing to give long sunny spells in the afternoon. Moderate northerly winds.

Additional weather information

Meteorologist's view

Tricky navigation in any low cloud and hill fog in the morning. Otherwise warmer and sunny with suitable sun protection and hydration advised.

Weather

A dry day with largely clear and sunny skies. A little cloudy at times in the north in the morning. Cloudier in the evening with high level cloud spreading southwards. Moderate to fresh northerly winds. Feeling warm in the sunshine.

Chance of cloud-free hill tops

80% chance in the morning, rising to 100% in the afternoon.

Low cloud and visibility

Some low cloud in the morning, mainly north, with base 500-700m. The top of the cloud will sit around 800m however so a chance of getting clear summits above this height, best chance in the south. Cloud lifting and clearing in the afternoon to give cloud free summits across the region. Poor visibility in the morning in low cloud, otherwise very good visibility.

Ground conditions

No recent ground conditions report available.
