Viewing Weather Forecast for Friday 17th August 2018
Forecast last updated on Thursday 16th August 2018 at 3:14pm

Tomorrow | Saturday | Sunday

How windy? (On the Munros)

Southwesterly 30 to 40mph, but increasing to 45 to 50mph from middle of the day.

Effect of wind on you?

Walking increasingly difficult across higher areas. Sudden gusts some lower slopes and walking arduous through some cols and passes.

How Wet? (Precipitation and its impact)

Drizzly rain, concentrated more western hills

Substantially dry post dawn, perhaps until nearly midday far north. But frequent drizzly rain will develop western mountains south from Torridon. Elsewhere, the rain patchy, although overall will tend to extend eastwards during afternoon. Will ease again evening.

Cloud on the hills?

Increasingly extensive

Some summits, mainly north of Torridon and well inland (from west coast) cloud free for some hours, mainly morning. But will deteriorate as blanket fog initially shrouds western hills from lower slopes up south of Torridon, then spreads inland across region through afternoon, although well inland mostly above 650m.

Chance of cloud free Munros?

30%, progressively dropping to almost nil

Air clarity (below cloud)

Sunshine rare, if any. Visibility often poor in rain, although excellent for some hours well inland and far north before deteriorating.

How Cold? (at 900m)


Freezing Level

Above the summits

Planning Outlook

All mountain areas of Britain from Saturday 18th August 2018

Mixed conditions will continue next week. Winds will remain generally westerly. There will be rain from time to time, although away from western mountains in Scotland, total rainfall will be fairly small. Low cloud will remain frequent, concentrated on more western mountains.
