Summary for all mountain areas

Severe conditions on mountains near the Irish Sea as upland gales or severe gales (Wales) spread inland ahead of a band of heavy rain and low cloud. Winds will strengthen into Scotland, but low cloud and a little rain will be mostly confined to southern Scotland.

Headline for Cairngorms NP and Monadhliath

Increasingly windy. Isolated rain, cloud shrouding higher areas.

How windy? (On the Munros)

Southeasterly, strengthening gradually from 20mph post dawn to 30mph early afternoon and 35 to 40mph evening.

Effect of wind on you?

Fairly small morning although will increasingly make walking arduous where exposed. Local sudden gusts extending to lower slopes from major ridges and summits.

Chance of cloud free Munros?

Almost certain by late morning Monadhliath; 30% elsewhere.

Planning Outlook

All mountain areas of Britain from Saturday 22nd July 2017

This weekend and early next week, winds often light, some areas of low cloud and constant rain, but overall frequently dry (despite fairly low pressure). Least rain will be in northern Scotland. Nevertheless one or two areas of strong winds. A weak ridge of high pressure will bring mostly fine conditions to the mountains early next week, but further strengthening winds and rain are likely to spread east across Britain mid-week. From then rain and low cloud will be frequent, particularly western mountains.
