Weather hazards

Gales High likelihood Hide detail

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.

Learn more about gales

Severe chill effect Low likelihood Show detail

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.

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.
