Summary for all mountain areas

Breezy south-southeasterly winds, strongest and gustiest in west. Areas of low cloud on hill slopes and fog in some valleys from dawn. Cloud tends to rise and break, but persisting on some south-facing hills. Better northwards across the Highlands.

Headline for The Northwest Highlands

Strengthening wind. Some cloud Skye, many hills clear with sun.

How windy? (On the Munros)

South to southeasterly, tending to increase 20 to 30mph, least wind in far north in the morning. Gusts reach 40mph Skye later in daytime. Increasing further into the night, gusty 35 to in places 45mph, strongest Skye.

Effect of the wind on you?

Becoming more blustery, starting to affect ease of walking and balance on exposed tops and ridges. Deteriorating with stronger winds into night.

How Wet?

Generally dry

Occasional local fine drizzle if in cloud on Skye.

Cloud on the hills?

Mostly little, patchy cloud Skye

Banks of cloud mostly southern areas of the Cuillin above 700-800m. Very patchy cloud elsewhere with hills often clear on mainland, particularly further toward northwest.

Chance of cloud free Munros?

50% south Cuillin, to 80% elsewhere.

Sunshine and air clarity?

Glimpses of sun Skye, sunnier overall further north, some thin high cloud builds. Visibility good, or very good northern areas, but some haze in west around Skye, improving into afternoon.

How Cold? (at 900m)

4C rising to 5 or 6C afternoon, but feeling near -5C in the wind, later colder in stronger wind on/near Skye.

Planning Outlook

Fronts moving in from the Atlantic by Sunday bring rain, widely setting in heavy for several hours, soonest Wales, here later clearing. A more unsettled outlook into next week as low pressure dominates with areas of rain and showers, which will vary locally day-to-day. Wind speeds will also vary, but some lulls. Potentially significantly colder later in the week with northerly winds, dropping below freezing on higher mountains, with snow showers especially Scottish Munros.
