Headline for The Northwest Highlands

Terrain nearly all frozen. Snow showers. Windy.

How windy? (On the Munros)

Northerly, 25 to 30mph generally strongest away from west coastal summits.

Effect of wind on you?

Cloud on the hills?

Frequently covering higher areas

Chance of cloud free Munros?

30% coastal areas and Sutherland to 80% southernmost summits

Planning Outlook

All mountain areas of Britain from Saturday 16th December 2017

Snow melt will be substantial from Sunday, although from Wednesday there will be a series of freeze thaw cycles on the Scottish Highlands. Rain (occasionally snow higher summits) intermittently W & NW Scotland, but elsewhere total rainfall small. Most forecasts indicate frequent stormy, often wet conditions from Christmas as a series of deep Atlantic lows come in. Intermittently snow will fall, particularly Scottish Highlands. However, a small minority of indicators suggest much colder, drier conditions eventually returning.
