Summary for all mountain areas

A murky day for many areas, with widespread fog across the hills, and patches of light rain or drizzle. The far north and northwest of Scotland will fare best for cloud breaks. Winds fairly light, but strengthening through the day on westernmost hills.

Headline for West Highlands

Low cloud and patchy drizzle. Wind strengthening to gale force far west.

How windy? (On the Munros)

Southerly 25-35mph, strengthening through the day from west; by afternoon risk 45-50mph over several hours on summits toward west coast.

Effect of wind on you?

Walking will be arduous, or perhaps difficult locally near west coast later. Some sudden strong gusts reaching lower slopes.

How Wet? (Precipitation and its impact)

Isolated drizzle

Isolated patches of light rain/drizzle; very little if any across Lochaber. May become more persistent coastal hills after dark.

Cloud on the hills?


Cloud likely to extensively shroud hills, lowest slopes upwards near and across Loch Lomond NP. Highest bases across Lochaber where some breaks are likely for a time before rain arrives from west.

Chance of cloud free Munros?


Air clarity (below cloud)

Little or no sun. Visibility generally good, but noticeable haze. Will deteriorate further in rain later.

How Cold? (at 900m)

3 or 4C.

Freezing Level

Above the summits

Planning Outlook

All mountain areas of Britain from Wednesday 12th December 2018

A battle between cold air to the east and milder air to the west will take place later this week, with confidence low about the general developments into the weekend. It looks increasingly likely that for a couple of days at least, freezing levels will drop markedly, and there is scope for some snowfalls, chiefly on eastern hills. As fronts push northeastwards, there may be a more organised fall of snow into the weekend. Cycles of freeze and thaw are then likely. Winds varied, up to gale force at times, giving severe wind chill.
