Summary for all mountain areas

A swathe of rain and gales sweeps across the Scottish Highlands, moving over the Southern Uplands with time; bright sun breaks and scattered showers follow from the northwest. Patchy rain for western hills of England and Wales, sunny breaks east. Blustery with rain increasing later in north England.

Headline for The Northwest Highlands

Morning rain and gales; rain breaks to showers, wind lessening

How windy? (On the Munros)

West-southwesterly 35-50mph through morning, stronger gusts briefly approaching 60mph over tops; lessening slightly afternoon though staying above 30mph and later restrengthening north.

Effect of the wind on you?

Arduous walking, buffeting affecting balance in exposure and more difficult conditions for several hours. Significant wind chill.

How Wet?

Morning rain, afternoon scattered showers

Frequent showery rain from dawn, setting in for a few hours of persistent rain with heavy bursts, a remote risk of a flash of lightning. Breaking into scattered showers afternoon, mostly west Munros with dry windows. A cluster of showers returns late in the day too.

Cloud on the hills?

Extensive through morning, lifting and breaking afternoon

Extensive above 600-800m at first, bases lower towards west coast and more widely to lower slopes during heaviest rain. Cloud will lift and break up somewhat afternoon, best chance of clear summits Easter Ross/Ben Wyvis; west fells only briefly clearing, and returning more widely for a time north.

Chance of cloud free Munros?

10%, rising to 60% east Munros

Sunshine and air clarity?

Overcast and dull with poor visibility through morning. Patchy sun breaking out afternoon, best in the west, with cloudier periods returning north and west. Very good visibility where cloud breaks, but some haze around Skye.

How Cold? (at 900m)

5 to 7C, coolest in the far north and will slightly rise, then lower again afternoon, as chilly at 4C in the north. Feeling like -5C in the wind, to as cold as -10C in strongest gusts.

Freezing Level

Above the summits.

Planning Outlook

Strong wind (often gale force on high mountains), patchy rain, and some broader swathes of rain and wind will affect the country from mid-week into the weekend; most notable areas of rain on Wednesday and late Thursday overnight into Friday. A few bright glimpses here and there, but many high summits stay shrouded, particularly western hill groups where cloud will often reach lower slopes. A brief bright window for some on Saturday, but staying windy with scattered showers in northwest areas, rain returning later and into Sunday. The next week remains generally unsettled, and may well bring a deep low pressure systems with widespread gales and swathes of heavy rain. Beyond next week, indications of a more settled regime for a time.
