Summary for all mountain areas

Hot sunshine persists across England, Wales, and southern Scotland; valley temperatures of 30C+. Starting bright and becoming very warm most of Scottish Highlands. Rain from Lochaber northward, later moving east with heavy thundery bursts forming over central/east highlands into evening.

Headline for West Highlands

Some drizzly rain to the north; sunny glimpses south

How windy? (On the Munros)

Variable less than 10mph most of the day. An easterly trend in the afternoon, sustained speeds rising to 10-15mph late in the day.

Effect of the wind on you?

Negligible.

How Wet?

Patchy rain northern hills

Drizzle affects coastal hills from Mull northward in the morning, a few patches of rain drifting here, merging into several hours of steadier falls. Southern hills stay dry. Later afternoon more widely dry, but some pop-up bursts of rain may form well inland late in the day.

Cloud on the hills?

Least cloud to the south

Often fairly extensive above the middle slopes near the Lochaber coast, mostly 900m and up inland but lower patches when rain occurs. Further south, varied banks of cloud on middle and upper slopes, several layers, not necessarily covering tops. A general lifting and breaking trend, but variably returning into evening.

Chance of cloud free Munros?

30% Lochaber, to 70% around Loch Lomond

Sunshine and air clarity?

Extended bursts of sunshine to the south, increasingly overcast to the north where dull for a time in rain. Some misty areas, particularly north, but largely very good.

How Cold? (at 900m)

Starting at 10C west of Loch Linnhe, to 13 to 15C inland and south, mildest over Arran. Rising slightly, up to 17C Ben Lomond to Arran (where valley temperatures approach 25C); staying nearer 13C northern Lochaber.

Freezing Level

Above the summits.

How windy? (On the Munros)

Generally easterly but variable, 10-15mph, most notable breezes south of Glen Coe; locally lower speeds too.

Effect of the wind on you?

Small.

How Wet?

Some patchy rain

Patches of light rain here and there through the day, many hills see extended dry windows. A greater risk of steadier falls well inland early, perhaps later around Ben Nevis and Glencoe groups.

Cloud on the hills?

Fairly extensive

Extensive from lower slopes upward at dawn; some varied broken cloud northwest of Loch Linnhe. Bases lift, unlikely rising above 800m well inland. Breaks approach 900m or higher towards the coast, but highly variable with lower banks returning.

Chance of cloud free Munros?

20%

Sunshine and air clarity?

Some brighter moments towards the coast but largely overcast; poor visibility on high terrain, to very good below cloud.

How Cold? (at 900m)

12 to 14C, rising a degree; mildest to the south.

Freezing Level

Above the summits.

How windy? (On the Munros)

East-southeasterly 10mph, to 15mph far south; some variability, particularly north where speeds often below 10mph.

Effect of the wind on you?

Small to negligible.

How Wet?

Likely dry

A small chance of a few spots of drizzly rain, but the Munros likely entirely dry.

Cloud on the hills?

Fairly extensive early, increasingly broken

Fairly extensive at dawn, lowest bases well inland where fog in some glens; some clear windows between layers possible on higher western terrain. Bases lifting and breaks forming, to banks above 1000-1100m inland, many western summits clearing for periods.

Chance of cloud free Munros?

20% rising to 70% western hills

Sunshine and air clarity?

Overcast and misty at dawn, sun bursts increasingly common to the west where visibility will be excellent.

How Cold? (at 900m)

11 or 12C at dawn, lifting to 14C, or locally 15C north of Mull. Some glens approaching 22C.

Freezing Level

Above the summits.

Planning Outlook

Staying warm in Scotland, hot for England and Wales into the weekend. High pressure shifts northward, facilitating a strengthening easterly wind across most areas. Some lingering cloud and rain over the Scottish Highlands Saturday with some risk of heavier thundery bursts on Saturday morning in the east. The weekend is likely dry across England and Wales with fairly extensive sun, some sea fog increasingly affecting northeastern hill groups later weekend. Easterly wind persists next week, sometimes quite strong England and Wales. Mostly sunny and very warm, including Scottish Highlands. Low pressure south of the country starts pushing showers into Wales, some heavy and thundery, though confidence is low. Detail increasing uncertain later next week, but Scotland likely stays dry.
