Summary for all mountain areas

Strong southwesterly winds, reaching near gale force on some tops, will result in low cloud shrouding the hills, extensively and to lower slopes in the west where rain and drizzle will be frequent. Highest cloud bases likely over the Cairngorms.

Headline for The Northwest Highlands

Blustery with frequent showers. Extensive hill fog in the west.

How windy? (On the Munros)

Southwesterly 25 to 35mph, perhaps 40mph for periods on higher, particularly summits toward the west coast.

Effect of wind on you?

Walking arduous across the hills, and on some higher coastal areas progress difficult.

How Wet? (Precipitation and its impact)

Frequent showers

Frequent showers will drive in from the west through the day; perhaps merging to give longer periods of rain across hills on and near Skye.

Cloud on the hills?

Extensive but base gradually rising

Extensive fog across the hills after dawn; lowest base western mountains south from Wester Ross. Will gradually improve; into the afternoon, cloud base 900 to 1100m; well inland summits frequently cloud free.

Chance of cloud free Munros?

20% in west, 70% in east

Air clarity (below cloud)

Patchwork of sunshine gradually coming through. Very good visibility, although slight haze.

How Cold? (at 900m)

11C dropping to 7C.

Freezing Level

Above the summits.

Planning Outlook

All mountain areas of Britain from Thursday 16th August 2018

Rain (a mix of showery days and those when rain sets in for a few hours) at some stage most days over the coming week or so. The heaviest and most persistent rain will be on western mountains, where fog will frequently shroud higher areas. Bands of upland gales or near gales will come through; the windy conditions most prolonged on the Scottish Highlands.
