Weather hazards

Gales Medium likelihood Show less detail

Progress will be impeded by very strong winds. Walking will be difficult and strenuous at times with a potential for one to be blown over in gusts. There can be a marked increase in winds through cols or on exposed ridges and summits. Distances often take longer to cover with compass bearings becoming more difficult to follow accurately.

Weather

Starting largely dry but cloudy with the best of any bright spells over Mull and Lochaber where some faint sunny spells possible; however the Trossachs and Goat Fell having thicker cloud and some fog on higher slopes with a few light showers soon developing. Then a tendency for cloud to thicken up from the east through the afternoon with showers becoming more numerous and briefly heavier, especially later for the Trossachs, south Argyll and Arran.

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

Cloud over Mull and Torridon mostly above 900 metres so some summits occasionally clear during the morning when incidence of clear summits 30% in west, but much reduced in south and east where often cloudy above 750 metres and only 20% chance in east. Chances reducing later in day.

Visibility

On west coast mostly good with mid distance hills discernible but distant hills obscure. Elsewhere mostly moderate with mid distance hills very faint and poor during heavier showers. On summits, and eastern facing slopes in east, occasionally poor as cloud banks move through.

Met Office Aberdeen meteorologist's view

Gusts of 50mph are likely on some summits till afternoon.

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.
