High confidence for generally unsettled, wet and breezy conditions over the coming days. Moderate confidence in the exact timing and extent of any 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.

Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.

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

Strong to gale force winds. Dry with sunny spells and low cloud at times.

Additional weather information

Meteorologist's view

Strong to gale force winds will make for strenuous walking conditions and a risk of being blown off balance. Sunny spells and high UV so suitable sun protection required.

Weather

A dry day with sunny spells developing at times. Strong west to northwesterly winds may reach gale force in the morning but easing a touch later in the day.

Chance of cloud-free hill tops

40% early morning, soon increasing to 80%.

Low cloud and visibility

Occasional low cloud with base 600-800m in the early morning. Cloud breaking up from late morning with bases rising to around 800-1000m. Visibility generally good but poor in cloud.

Ground conditions

No recent ground conditions report available.
