Summary for all mountain areas

Humid southwesterly air brings extensive low cloud and drizzle to many mountains. Locally drier with some cloud breaks toward northeast of major mountain groups. Around Skye generally wet all day, whilst more prolonged heavier rain likely moves into southwest Scotland afternoon-evening. Strong and gusty winds.

Headline for West Highlands

Blustery, gusty; low cloud and drizzle, patchy rain, wetter later.

How windy? (On the Munros)

Southwesterly 30 to 45mph, speed varying locally and during the day, tending to generally rise during afternoon; some notable strong gusts including on some north and eastern downslopes.

Effect of the wind on you?

Some variations, but often affecting comfortable walking in exposure, with time increasingly frequent buffeting, very gusty in places affecting stability, not just highest terrain. Wind chill becoming considerable despite mild air.

How Wet?

Drizzle, some rain mostly northwest, likely wetter extensively later

Rain and drizzle fairly persistent from dawn Mull to Ben Nevis group, staying generally damp all day west of Loch Linnhe. Patchy and light elsewhere, some drizzle, otherwise dry for a few hours well inland. During afternoon and particularly toward evening, persistent rain developing widely from southwest, setting in heavier.

Cloud on the hills?

Extensive, lowest coasts, rare local breaks

Shrouding most mountains all day, from mid-slopes up around many west and south-facing groups, lower patches in rain. Higher bases inland generally north of Crianlarich around 600-800m, best of breaks to some upper slopes northeast of Ben Nevis group, but rarely clearing high tops.

Chance of cloud free Munros?

10%

Sunshine and air clarity?

Rare glimpses of weak sun well inland, but largely overcast and dull. Poor visibility in rain, locally better below cloud inland at times, but a haze likely.

How Cold? (at 900m)

9 or 10C, locally slightly warmer northeast Lochaber, little change all day; then lowering only well into night to 6C. Feeling just below 0C directly in wind.

Freezing Level

Above the summits.

Effect of the wind on you?

Blustery start, easing to fairly small effects for a time, but conditions become strenuous, or later arduous.

Cloud on the hills?

Lifting, high breaks for a time, then deteriorating

Cloud banks at varied heights in the morning, clear windows between layers which may include summits. Cloud will tend to lift and break up, varied layers on high terrain linger towards the coast. Will increasingly fill in from mid-afternoon onward.

Chance of cloud free Munros?

50%, deteriorating from mid-afternoon

Sunshine and air clarity?

Patchy sunshine, most extensive south of Rannoch Moor, high cloud thickens from the west later. Good visibility.

Planning Outlook

Staying unsettled during the next week to 10 days as westerlies prevail - areas of low pressure passing north of Scotland with frontal systems bringing frequent rain, wettest over western mountains in Scotland. Often windy, sustained periods of gale-force westerly winds over higher terrain. Fairly cool by Tuesday onward, close to freezing on highest Scottish summits on Wednesday morning, possibly again for a time next weekend; often considerable wind chill on the mountains. Higher pressure and better weather tends to expand further north later in month.
