Summary for all mountain areas

Inversion conditions still probable over Scottish Highland summits; exposed rock in fog below the inversion may be slippery, notably early. High Lakeland and Snowdonia summits near or above cloud as well. A mix of cloud and sun elsewhere as morning fog lifts, some haze below cloud later. Feeling mild to warm.

Headline for West Highlands

Summits above inversion, hazy with patchy sun lower slopes

How windy? (On the Munros)

Westerly or variable, 10mph or less, rare gusts up to 15mph.

Effect of the wind on you?

Small

How Wet?

Rain unlikely

Fine drizzle possible on some windward coastal slopes where within cloud banks, most likely early in the day. Rock surfaces may be slippery where in fog.

Cloud on the hills?

Cloud rises to middle elevations, tops above inversion

Fog in the glens at dawn with local banks up to middle slopes near the coast. Higher Munros inland likely above the cloud layer all day. Cloud layer lifts to the middle slopes, well-broken in many places. High tops above the cloud.

Chance of cloud free Munros?

90% (above top of a cloud layer)

Sunshine and air clarity?

Lower areas particularly toward west often cloudy with bursts of sun; some haze. Higher terrain above the inversion will be sunny with very clear air, just some scattered high cloud around.

How Cold? (at 900m)

10 or 11C in the morning, much cooler lower down below the cloud layer. Becoming near 10 or 11C for most, perhaps warmer on the exposed high tops.

Freezing Level

Above the summits.

How windy? (On the Munros)

Variable 10mph or less. Locally gusty at all elevations.

Effect of the wind on you?

Negligible

How Wet?

No rain expected

Exposed rock surfaces in the fog at dawn may be slick, mostly middle and lower elevations.

Cloud on the hills?

High tops above a cloud layer

At dawn, variable cloud at multiple levels largely below 800m. Well-broken inland, perhaps mostly just in the glens. Cloud base will lift with patches up to higher slopes though high tops above 1000m likely remain above cloud layer.

Chance of cloud free Munros?

70% (highest tops above cloud layer)

Sunshine and air clarity?

Sunny on the highest tops in very clear air. Patchy sun below the cloud layer where some haze will linger.

How Cold? (at 900m)

6 to 8C, warmest on coastal hills from Mull southward. High tops above inversion start warmer, may rise into the low teens.

Freezing Level

Above the summits

How windy? (On the Munros)

Variable 10mph or less.

Effect of the wind on you?

Negligible

How Wet?

Damp air where in cloud

Where within fog, some very fine drizzle drifting around and rock surfaces will be slick.

Cloud on the hills?

Cloud lifts to upper slopes

From dawn, fairly extensive on middle slopes near the coast with lower bases from Mull northward. More broken inland, cloud top near 1000m at first. Cloud layer will lift, remaining most extensive near the coast.

Chance of cloud free Munros?

70% on the tops, lowering to 50%

Sunshine and air clarity?

Highest tops above an inversion at least in the morning. Little sun below the cloud near the coast. Good visibility below cloud.

How Cold? (at 900m)

5 or 6C

Freezing Level

Above the summits

Planning Outlook

High pressure lingers over the country through the later days of this week: in the mornings, varied low cloud and valley fog is likely with highest tops still possibly above the cloud layer. As the weekend approaches, the inversion starts to weaken as pressure begins to fall gradually; cloud will begin to lift to higher slopes, starting to shroud mountain peaks more often. Local cloud breaks, best of breaks in west Wales, though a haze will linger on low slopes while high pressure remains in charge. Light winds overall, an easterly breeze likely for Wales. Next weekend looks to be transitional as low pressure becomes favored. Winds rising with increasing cloud and a risk of rain.
