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.

Thunderstorms
Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.

Mountain weather forecast

Some early cloud and light rain possible clearing to leave another very warm and dry day with sunny intervals.

Additional weather information

Meteorologist's view

Feeling very warm and humid, the risk of heatstroke on long and strenuous hikes should be considered.

Weather

Some early morning rain will affect northern and western ranges but this should lift and clear with long sunny spells developing. Later in the evening cloud will build with the risk of a shower towards the northwest of the area.

Chance of cloud-free hill tops

70% in the north, 90% in the south.

Low cloud and visibility

Patches of cloud around 800m are likely early in the day in the south and scattered cloud layers above 600m expected at first in the north. Most cloud will lift above summits in the afternoon but may reform in the evening around Lochaber hills as showers move towards the area. Visibility will be good or very good throughout the day, perhaps a little hazy in the west in the afternoon, visibility may turn moderate in any evening showers.

Ground conditions

No recent ground conditions report available.
