Summit specific forecast
Mountain summit forecast map
Including Ben Nevis, Glen Coe and the rest of Lochaber, Argyll including the Isles, Loch Lomond, Trossachs and Arran
The Southwest Highlands weather forecast area is an extensive area of mountains, moorland, islands and sea lochs. The area has a high density of steep and rugged Munros (Scottish mountains over 3000 feet) including the highest mountain in the British Isles, Ben Nevis (1,344 metres), 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. Glen Coe is also an iconic area for rock climbing and scrambling and includes the Aonach Eagach, an exposed and narrow ridge which stands 900m above the floor of the glen below.
The Loch Lomond and Trossachs National park was the first of the two national parks in Scotland and includes Ben Lomond which is the most southerly Munro. Running past the foot of Ben Lomond is The West Highland Way which is Scotland's first long distance walking route. It stretches for 96 miles from Milngavie on the edge of Glasgow to Fort William.
The Isle of Arran is in the far south of the area, often referred to as Scotland in miniature, it includes Goat Fell with its fine panoramic views and the Glen Rosa horseshoe with sections of rock scrambling.
