Weather hazards

Strong sunlight High 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.

Weather

Dry and quite clear overnight though some cloud spreading into Mull and Lochaber, quite cool at dawn. After sunrise a bright dry day with high thin cloud allowing occasional hazy sunshine. The only exception may be Lochaber and Mull where cloud a little more persistent, especially Lochaber during the morning and evening with some fog over Nevis and other Munro summits.

Chance of cloud-free mountain/hill tops at 800m

80% or more in southeast with cloud all relatively high and thin, 60% in northwest with some temporary banks on summits, especially early and late in day over coastal Lochaber, Nevis and other highest peaks.

Visibility

Excellent with distant hills and coastal features discernible though moderate at times over coastal Lochaber.

Met Office Aberdeen meteorologist's view

Temperatures generally 3 degrees higher overnight at 1300m so not as notable a windchill. Temperature in Trossachs valleys will reach 18C during the afternoon so feeling warmer than recently.

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.
