Summary for all mountain areas

Showers in west Scotland from dawn, spreading east. Gales across the highlands, severe northwest, feeling cold. Early rain in England and Wales breaks for sun through high cloud, windy in the north. Prolonged rain arrives into south Scotland from midday, spreading into north England with time, and later Wales.

Headline for West Highlands

Showers, some prolonged falls; gales become widespread

How windy? (On the Munros)

Southwesterly 40 to 55mph, tending to strengthen, sustained speeds reaching 60mph with stronger gusts over Ben Nevis.

Effect of the wind on you?

Arduous walking in exposure most of the day, becoming difficult over higher terrain as the day goes with buffeting making any mobility challenging; significant wind chill.

How Wet?

Showers increasing

Showers much of the day, some heavy bursts and merging into prolonged falls at times towards the south. Some chance a few hours of persistent rain, again mostly southern mountains. Wet underfoot, fast-flowing streams.

Cloud on the hills?

Fairly persistent higher areas

Often capping most high mountains, bases varying around rain, but rarely above 900m toward coasts, at times 600m. Sometimes lifting to 1000m or above inland, best breaks near Rannoch Moor to Glen Spean. Some periods of more extensive cloud from Glencoe southward are possible.

Chance of cloud free Munros?

20% towards coast; to 40% north of Rannoch Moor

Sunshine and air clarity?

Patchy sunshine, best inland; some more broadly cloudy periods towards the south. A haze towards the coast, visibility often poor in cloud and rain, but locally improving well-inland.

How Cold? (at 900m)

6 or 7C, little change all day. Feeling like -5C, to -10C in strongest wind on high tops.

Freezing Level

Northwesterly 25-35mph, easing, shifting westerly, 15mph afternoon and locally less.

Effect of the wind on you?

A blustery start and feeling chilly, easing to small effects.

Well-scattered light showers will drift onto the coast and hill groups from Glencoe northward, tending to fade to largely dry conditions.

Cloud on the hills?

Rising to high terrain, breaks inland

Varied cloud banks from middle slopes up, local lower patches where sheltered, but soon dissipating and lifting, mostly isolating above 900m and increasingly breaking up inland. Summits nearest the coast, as well as highest inland summits, will struggle to clear.

Chance of cloud free Munros?

Rising to 50%

Sunshine and air clarity?

Patchy sunshine breaking out, extended windows increasingly. Very good visibility.

How Cold? (at 900m)

Planning Outlook

Generally unsettled through next week with spells of rain and showers moving in from the Atlantic, accompanied by strong to gale force mountain winds. Temperatures will vary, mildest toward the south, but cooler air moves in from the north at times bringing higher Scottish tops occasionally close to freezing point, feeling cold in the wind chill. A few high pressure ridges bring settled windows, notably afternoons of Wednesday and Friday; northwestern areas, particularly in Scotland, will tend to hold onto some hill cloud despite high pressure. An unsettled weekend is indicated, followed by a rising chance of longer settled windows from mid-month, particularly England and Wales. Temperatures will be generally near or above average, best sunny windows east hill groups.
