Summary for all mountain areas

Extensive fog due to low cloud and patches of drizzle, but dry most western mountains where cloud base highest. Little wind N Scotland, but from near the central belt of Scotland southwards, blustery higher slopes, and in places very gusty west of major ridges.

Headline for West Highlands

A little drizzle, mainly near central belt, where blustery.

How windy? (On the Munros)

Easterly 20 to 30mph, strongest Loch Lomond NP, particularly Trossachs to hills near Clyde sea lochs where sometimes 35 or perhaps 40mph.

Effect of the wind on you?

Small, though locally near the coast sudden gusts may impact balance.

How Wet?

Little or no rain

Risk of a few patches of drizzle Loch Lomond NP, mainly east of Loch Lomond and Crianlarich and Arran.

Cloud on the hills?

Very extensive, though sometimes clearing some western areas

Persistent fog above 600-800m, but from the Trossachs to hills near Clyde sea lochs patches at 300m, particularly morning. Areas above 1050m may be above the cloud. The cloud sheet may extensively or intermittently break up toward and west of Loch Linnhe.

Chance of cloud free Munros?

30% - but fog many lower slopes

Sunshine and air clarity?

Extensively cloudy, but perhaps bright sunshine toward the coast in Lochaber. Visibility excellent, though a haze near central belt.

How Cold? (at 900m)

2C to 4C, warmest near and west of Loch Linnhe. In the wind near central belt will feel as cold as minus 6C.

Freezing Level

Above the summits, but frost at dawn some valleys and in places ground frozen on highest tops.

How windy? (On the Munros)

Easterly, 10 to perhaps 15mph (strongest near central belt).

Effect of the wind on you?

Negligible

How Wet?

Little or no rain.

Particularly Loch Lomond NP, intermittently 'damp' as light or very light rain falls for intermittently. Mostly or completely dry Lochaber.

Cloud on the hills?

Extensive

Confidence low (as low cloud drifts only slowly and the height of the top of the cloud also changes). Broadly, cloud base typically 500 to 800m with the top 1100m or above. But particularly Loch Lomond NP and Arran, areas of cloud may be below 450m.

Chance of cloud free Munros?

20% (in places with fog lower slopes)

Sunshine and air clarity?

Overall extensive or particularly Loch Lomond NP, persistent cloud. Probably sunny some areas - best chance Lochaber. The air very clear; haze some lower slopes.

How Cold? (at 900m)

2C

Freezing Level

Above the summits - frost some valleys overnight and perhaps ground frozen higher tops.

How windy? (On the Munros)

Direction varied, 10mph or less, perhaps easterly 15 or 20mph near central belt.

Effect of the wind on you?

Mostly negligible

How Wet?

Risk drizzle, most likely near central belt

Risk isolated fine drizzle, although the drizzle may come and go for periods eastern an southern Loch Lomond NP.

Cloud on the hills?

Probably very persistent, but Lochaber may be largely fog free

Confidence in detail low: Extensive slowly drifting low cloud will affect much of region between 200-400m and around 700 to 900m - higher areas above cloud. The cloud is least likely to reach Lochaber.

Chance of cloud free Munros?

50% - fog many lower slopes.

Sunshine and air clarity?

Areas of bright sunshine and excellent or superb visibility most likely Lochaber. Otherwise cloudy.

How Cold? (at 900m)

2C

Freezing Level

Above the summits - but some particularly higher terrain frozen after a frost.

Planning Outlook

High pressure will continue to be the main influence through the next week, particularly W & NW Highlands where extensively dry and wind often light. However, generally fog and low cloud may well never clear most mountains under the light wind. There will also be patches of drizzly rain, although total rainfall small.
