The Northwest Highlands
Areas north from Knoydart in the west, and the Great Glen towards the east (NB. Does not include Mull and areas west of Loch Linnhe, these are found in the West Highlands forecast.)
Today's Forecast
Light wind, negligible impact
Little wind or walking hardly affected by the wind, but feeling chilly if exposed on tops. 10-15mph or less.
Dry, Inversion
Banks of cloud or fog on lower or middle slopes, but higher terrain likely clear and sunny above an inversion.
Hazy, some fog banks
.jpg "Hazy, some fog banks"){kind=icon}
Hazy views with lack of air clarity, particularly on lower terrain, some fog banks on hills making navigation locally more difficult. If above an inversion, the air outstandingly clear.
Cool to mild
Air temperature 5 to 10C on higher terrain. Comfortable temperatures on lower terrain, but feeling chilly if exposed to wind higher up, especially if stationary. Pack extra layers.

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 The Northwest Highlands
High southern tops above inversion, cloudier north
How windy? (On the Munros)
Westerly 10 to 15mph, or less on some slopes, but over northern mountains gusts 20mph in places.
Effect of the wind on you?
Mostly small
How Wet?
Rain unlikely
Fine drizzle possible on some windward western slopes where within cloud banks, greatest risk in the far north. Rock surfaces may be slippery.
Cloud on the hills?
Fairly extensive, highest tops south at or above cloud top
From dawn, extensive near the coast and northern areas. More broken southern inland areas, concentrated on low slopes and in glens. Bases lift to middle and upper slopes, remaining extensive north. Best of breaks south of Ullapool where highest tops at or above the cloud layer.
Chance of cloud free Munros?
40% north in the morning, lowering to 20%; 80% southern high tops
Sunshine and air clarity?
Most western areas largely cloudy, misty or dull lower down. Highest summits in the south above the cloud layer will see extensive sun in very clear air.
How Cold? (at 900m)
5 to 8C in the morning, coolest in the north; little change in temperature downslope. Mountains south of Torridon may rise to 9 or 10C, particularly if tops are above the cloud.
Freezing Level
Above the summits.

Effect of the wind on you?
Mostly small.
How Wet?
Likely dry
Small chance of light spotty rain in the north. Dry elsewhere.
Cloud on the hills?
Banks of cloud lifting to higher slopes
At dawn, variable cloud at multiple levels largely below 900m. Towards Kintail and Ben Wyvis, possibly only a layer of low fog. Cloud lifts to between 700-1000m, variably coming and going. North of Ullapool, may fill in more widely and over tops at times.
Chance of cloud free Munros?
70% at dawn (high tops above cloud), lowering to 50%
Sunshine and air clarity?
Patchy sunshine, may become more overcast towards the north. Excellent visibility on highest slopes, particularly early, some haze lower.
How Cold? (at 900m)
6 or 7C; warmer on summits if above cloud. Cooler inland glens at dawn.

How windy? (On the Munros)
Mostly variable 10-15mph, at times less. In the far north, a gusty northwesterly 15mph.
Effect of the wind on you?
Mostly small
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?
Fairly extensive, bases lift somewhat
Extensive from dawn with lowest bases near the west coast. More broken on lower terrain near Kintail/Ben Wyvis. Bases rise towards 600-700m, higher bases well east, but most high terrain remains shrouded, only a few odd breaks.
Chance of cloud free Munros?
20%
Sunshine and air clarity?
Little or no sunshine. Good visibility under the 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.
