Summary for all mountain areas

A front lies across the far north of Scotland, producing areas of rain or showers and cloud shrouding the hills. Fewer showers further south across the Highlands, with cloud breaks to many tops. A strengthening breeze. England & Wales largely dry with sunshine, broken cloud.

Headline for The Northwest Highlands

Rain frequent north/west; low cloud. Blustery, feeling cool.

How windy? (On the Munros)

West to northwesterly, 20 to 25mph, strongest northern tops, 30mph for a few hours afternoon.

Effect of wind on you?

Fairly small, but may be blustery for several hours, especially toward the north; feeling cool in exposure.

How Wet? (Precipitation and its impact)

Showery rain, may merge to give rain over several hours locally

A risk of frequent rain over many hours on western hills from Wester Ross northwards, may fall as snow on highest tops in morning. Elsewhere, occasional showers through the day, mostly confined inland by afternoon. Possible hail. A chance of more persistent rain developing across Caithness and Sutherland during afternoon.

Cloud on the hills?

Fairly extensive

A risk of extensive cloud covering northern tops, in places below 600m. Banks of cloud may also often cover hills on/near Skye. Breaks to higher tops near Great Glen.

Chance of cloud free Munros?


Air clarity (below cloud)

Mostly cloudy, patches of sun. Visibility very good away from showers, but often dull where rain lingers.

How Cold? (at 900m)

2 or 3C from dawn, rising toward 5C, perhaps a degree or so higher near Great Glen.

Freezing Level

Above the summits. Slight frost possible some glens and corries around dawn.

Planning Outlook

All mountain areas of Britain from Thursday 23rd May 2019

A slack pressure pattern continues, with low pressure centred toward the northeast. Rather cool across northern Scotland for the rest of this week. Many places largely dry with just local brief showers or patches of drizzly rain. Mixed conditions prevail into the Bank Holiday weekend and beyond, with fairly low pressure in charge, but weather systems still moving around slowly. Expect rain from time to time, plus some heavy showers, in places giving rain for several hours. Cloud often shrouding higher terrain during or after rain. Temperatures around average for late May.
