Summary for all mountain areas

Variable hill cloud at dawn, early rain in Wales into Lakeland and south/eastern Scotland; NW Scotland starts clear. Most cloud lifts to or above summits. Heavy afternoon showers build over the Pennines northward across most of Scotland; risk hail and local thunder. Risk lingering rain south Wales.

Headline for West Highlands

Cloud lifts to highest summits, heavy afternoon showers

How windy? (On the Munros)

Southerly 5-10mph at dawn, soon shifting southeasterly. Slowly rising towards 15-20mph around evening, though some strong gusts around showers, and may approach nearer 25mph southern islands. Deteriorating overnight.

Effect of the wind on you?

Fairly small, but likely more noticeable on coastal tops, particularly towards the southern islands later in the day.

How Wet?

Heavy afternoon showers inland

Odd spots of rain in the morning, mostly southern islands, but most Munros dry until around midday. Scattered showers form afternoon, suddenly increasing in strength and frequency from approximately Loch Lomond through Glencoe into Lochaber; generally dry west of here. Rising risk of hail and localised thunder.

Cloud on the hills?

Mostly clearing, lingering on highest terrain towards central highlands

Varied cloud banks in the morning, mostly upper slopes of southern hills, some inland mist in glens too. Cloud lifts to largely clear most Munros, though clings to the high tops of Ben Nevis group and towards central highlands. Cloud returns above 900-1000m in later showers, again towards central highlands.

Chance of cloud free Munros?

60% well inland, to 80% near the coast

Sunshine and air clarity?

A patchwork of cloud and sun most of the day, some periods of thicker cloud towards the central highlands, also cloudier in the morning south. Very good visibility, but poor periods where showers form.

How Cold? (at 900m)

2C rising to 6C, or perhaps milder to the north.

Freezing Level

1100-1200m at dawn, plus slight frost in glens towards the north. Rising above all tops.

How windy? (On the Munros)

Southeasterly 40-50mph early with notable gusts. Shifting southerly afternoon and easing to 25-30mph, or lower later.

Effect of the wind on you?

Arduous walking with considerable buffeting and wind chill early; easing, but remaining a nuisance well into the day.

How Wet?

Rain most of the day

Near-constant rain from before dawn breaks into frequent showers, these at times merging into broader areas of rain, most persistent south coastal areas. Slippery rock surfaces and risk of isolated hail and thunder to the south.

Cloud on the hills?

Fairly extensive

Most hills shrouded to at least middle slopes in the morning, many areas to lower slopes. A lifting trend with time, near 900m inland with some high breaks; north/west slopes always clearest. South coastal hills will struggle to clear above 500-700m.

Chance of cloud free Munros?

20%

Sunshine and air clarity?

Few weak glimpses of afternoon sun, otherwise overcast and dull. Visibility largely poor in cloud and rain.

How Cold? (at 900m)

4 or 5C, rising to 7 or 8C, mildest towards Creag Meagaidh. Feeling like -5 to -10C in direct wind.

Freezing Level

May be near freezing just on the high tops at dawn, but soon lifting above the summits.

How windy? (On the Munros)

Westerly 15-25mph; strongest speeds Mull and southward.

Effect of the wind on you?

Fairly small, though may be blustery in exposure south of Mull.

How Wet?

Often raining

Several periods of rain are likely to affect all Munros, lasting for several hours at a time. Some breaks in the rain, but remaining drizzly on the high tops, particularly towards the coast from Mull southward; slippery rock surfaces.

Cloud on the hills?

Fairly extensive

Cloud shrouds coastal slopes from 600-700m upward all day, and perhaps to the lowest slopes/coastal cliffs during heaviest rain. Cloud to low slopes inland at dawn as well, this lifting as high as 1000m during rain breaks, but returning lower too.

Chance of cloud free Munros?

10%

Sunshine and air clarity?

Overcast and often dull. Visibility largely poor in cloud and rain.

How Cold? (at 900m)

5C rising to 7 or 8C well inland; little change along the coast.

Freezing Level

Above the summits.

Planning Outlook

A mixed but milder outlook. Damp southwesterlies prevail for a few days as mid-week approaches with regular rain and showers, most on western hills where drizzly rain may persist between showers and persistent low cloud. Expect increasingly wet conditions underfoot and slippery rock surfaces. Also, a risk of isolated hail and lightening in the showers; showers may be enhanced in eastern Scotland in sea breezes. Indications of rising pressure later in the week, brining milder and drier conditions to England and Wales. However, some drizzle and low cloud may continue to affect western hills, with periods of rain and wind continuing to affect Scotland. Pressure may continue to rise into the weekend, allowing for warmer and sunnier conditions, but some fronts and lingering humidity will bring local periods of rain.
