Summary for all mountain areas
Inversion conditions widely across Scottish highlands. High tops of Lakeland and Snowdonia also likely above a cloud layer. Feeling quite warm in the autumn sunshine on summits above the cloud; valleys and glens starting cooler. Cloudier over Pennines and east Wales, most fog rising to high terrain with local breaks.
Headline for The Northwest Highlands
High summits above mid-level cloud; warm in sunshine
How windy? (On the Munros)
West or southwesterly though variable, 10-15mph but often less. Gusts are likely at all elevations.
Effect of the wind on you?
Small
How Wet?
No rain
Cloud on the hills?
Broken cloud at middle elevations, risk higher north
Fog in many glens at dawn with banks up to middle slopes, perhaps more extensive near the west coast. Low fog will lift with banks persisting between 600-800m, higher terrain above cloud. A risk of higher, more sheet-like cloud to the far north; high tops more marginal to be above cloud.
Chance of cloud free Munros?
80% (summits above cloud)
Sunshine and air clarity?
Mostly sunny above the cloud layer, some high cloud may weaken sun at times. Excellent visibility above the cloud layer, some low-level haze.
How Cold? (at 900m)
11C; glens starting much cooler inland. Feeling warm above the cloud layer where temperatures may rise several degrees.
Freezing Level
Above the summits

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.
Cloud on the hills?
Fairly extensive, highest tops may be clear
Cloud banks around mid to upper slopes, particularly western mountains, likely to persist all day. Highest summits near or just above top of the cloud at times, but toward far north cloud may drift higher up.
Chance of cloud free Munros?
60% (just above top of a cloud layer)
Sunshine and air clarity?
Most western areas largely cloudy, misty or dull lower down. Highest summits may just poke out into sun and very clear air above an inversion.
How Cold? (at 900m)
6C, small variation from lower slopes upward in morning, whilst highest tops warmer than mid-heights all day.
Freezing Level
Above the summits. Possible slight frost inland glens at dawn.

How windy? (On the Munros)
Generally variable 15mph or less. North and eastern areas may see NW'ly winds up to a gusty 20mph.
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 patchy cloud at multiple levels (including in the glens) though largely below 900m. 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 to 8C; warmer on summits if above cloud. Cooler inland glens at dawn.
Freezing Level
Above the summits
Planning Outlook
High pressure resides over the country through the week, maintaining quiet weather. In the mornings, varied low cloud and morning fog is likely while inversion conditions likely to remain over highest mountains for several days. A haze will linger on low slopes below the inversion. During midweek the inversion starts to weaken as pressure begins to fall gradually; cloud will be well-broken for many and begin to lift to higher terrain. Light winds overall, an easterly breeze likely for Wales. Uncertainty about the weather pattern development toward next weekend: some indication of strengthening winds bringing some rain, but may not reach all areas. Later October has hints of chillier northerly air, especially in Scotland.
