Summary for all mountain areas

Exceptionally hot in England and Wales, fire risk remains high. Despite haze and high cloud, beware sunburn and dehydration. Warm too in Scotland. Hill cloud and showery rain affects west Scotland from morning, patches spreading east; rain becomes frequent west Scotland later with heavy bursts.

Headline for West Highlands

Periods of rain, frequent later north, heavy bursts

How windy? (On the Munros)

Southwesterly between 15 and 25mph, strongest near and west of Loch Linnhe, where sustained speeds will approach 30-35mph through afternoon.

Effect of the wind on you?

Mostly fairly small, though walking becomes strenuous on high Lochaber summits later in the day.

How Wet?

Patchy rain, becoming frequent with heavy falls

Pulses of rain drift from the southwest through morning, most common Jura and northward; generally light and patchy eastward. Becoming more frequent as afternoon goes with extended heavy falls, risk of thunder in the north.

Planning Outlook

Some rain and a fresh northwesterly breeze slips into England and Wales on Friday. Though weekend, high pressure is never far away to the southwest, keeping conditions generally drier and brighter across England and Wales, though a northwesterly flow will bring some cloud to western hills. Scotland is more often cloudy with patchy rain, mostly north and west. Mixed conditions early next week with periods of rain and sunny bursts. High pressure remains present to the southwest of the British Isles, maintaining the possibility of drier brighter days; detail remains uncertain regarding risk of more unsettled weather. Temperatures likely nearer average.
