Summary for all mountain areas

Strong winds, areas of rain and low cloud will extend southwards from S Scotland into N England and later N & W Wales. Over Highland Scotland, the remnants of overnight rain will turn increasingly showery, with risk of thundery downpours in afternoon.

Headline for The Northwest Highlands

Risk windy later. Areas of low cloud and rain; thunder possible.

How windy? (On the Munros)

Direction varying, but turning northerly 10 to 20mph. Later in day strengthening toward 30mph, or perhaps 35mph coastal summits.

Effect of wind on you?

Small but perhaps fairly quickly, particularly coastal summits, buffeting becoming significant in the afternoon.

How Wet?

Frequent rain; risk lightning.

Intermittent rain will continue into the day but will tend to become more showery. But risk heavy rain and thunder, particularly inland afternoon and evening.

Cloud on the hills?


Cloud will envelop the hills widely, in some areas from lower slopes upward in morning. The base will become more variable as in afternoon, breaks develop to 900m, perhaps higher south of about Torridon.

Chance of cloud free Munros?

Less than 10%

Sunshine and air clarity?

Rare glimpses of the sun. Fog extensive and visibility often restricted by rain lower areas.

Planning Outlook

All mountain areas of Britain from Friday 22nd August 2014

Until Sunday night, cold on the mountains - and also at night in many valleys with ground frost some nights. The air very clear and many summits free of cloud; although there will be showers - these dying out through the weekend when the wind will gradually drop away. Rain and areas of low cloud will come in on Monday as an Atlantic low approaches and then crosses Britain. However, the rain may largely miss the NW Highlands. Through the week, generally unsettled, with further rain from time to time.
