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.

Severe Chill Effect
Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.

Additional weather information

Meteorologist's view

Windy conditions at times will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times. Feeling chilly at height with the strong winds.

Weather

Largely dry in the morning with bright or sunny spells, just the small chance of the odd shower. Still bright spells but more showers developing during the afternoon. Cloud and rain spread north through the evening. Feeling quite chilly on the summits.

Chance of cloud-free hill tops

90% or higher in morning, 70% afternoon.

Low cloud and visibility

Summits clear with good visibilities in the morning and any patches of cloud above summits. Cloudier in the afternoon, though still mainly above the summits. Some patches of cloud may drop to around summit level and visibilities fall moderate or poor as any showers pass through in the afternoon. More widespread cloud pushes north in late evening.

Ground conditions

No recent ground conditions report available.
