Weather hazards

Strong sunlight Medium likelihood Hide detail

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 Low likelihood Show detail

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.

Thunderstorms Low likelihood Show detail

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.

Very good outside showers with good air clarity.

Met Office Aberdeen meteorologist's view

Be prepared for cold winds and notable wind chill at height, note the below freezing 'feels like' temperature on the highest tops.

The South West Highlands is an extensive area of mountains, moorland, islands and sea which is home to several distinctly different cultures. The West Highland Way was Scotland's first long distance route and remains by far the most popular. It stretches for 94 miles from Milngavie on the edge of Glasgow to Fort William at the foot of Ben Nevis.

The South West Highlands area is very sparsely populated, with many mountain ranges including the highest mountain in the British Isles, Ben Nevis, standing at 1,344 metres. This mountain is a popular destination attracting an estimated 100,000 ascents a year. The 700 metre cliffs of the north face are among the highest in the UK, providing classic scrambles and rock climbs of all difficulties for climbers and mountaineers.
