Summary for all mountain areas
Windy in Scotland with gale-force gusts over high terrain. Much upper Highlands terrain in cloud, some rain and drizzle (most in the west); best breaks north of major hill groups. Varied cloud early in England and Wales, mostly clearing with increasing sun, though visibility limited by haze. Cool to mild England and Wales.
Headline for Eryri / Snowdonia National Park
Early cloud substantially clearing, though hazy; breezy in exposure
How windy? (On the summits)
Southerly 20 to 25mph, in places gusty 30mph around higher tops, lighter speeds likely early in the day. Wind will strengthen overnight.
Effect of the wind on you?
Fairly small early in the day, becoming blustery over higher terrain, affecting ease of walking and balance on exposed ridges and felling chilly. Deteriorating overnight.
How Wet?
Little if any precipitation
A little damp air/fine mist in early cloud, a small risk of an odd spot of rain drifting northward across the westernmost hill of Snowdonia NP, but most hills entirely dry.
Cloud on the hills?
Early low cloud lifting
Varied cloud banks in the morning tending to lift and gradually break above many hills. Areas north and northwest of Ogwen valley clearer overall, only broken patches here. Some cloud will cling to the upper slopes of the Berwyn group.
Chance of cloud free summits?
40% rising to 70%
Sunshine and air clarity?
Early cloud will lift and break, most slopes seeing plenty of sunshine afternoon; some cloud may linger in east Wales. Haze will limit distant visibility.
How Cold? (at 900m)
6 or 7C, may rise slightly overnight (though cooling on lower slopes). Feeling just above freezing in direct wind.
Freezing Level
Above the summits.

South-southwesterly 20-30mph, a gradual easing, towards 15-20mph evening, may lower for a time into night.
Effect of the wind on you?
Strenuous walking with a notable chill in exposure early; improving, may become fairly small.

The morning likely dry, then a risk of showers in the afternoon which may be locally heavy. Into evening, patchy rain lingers.
Cloud on the hills?
Clear periods, deteriorating with time
Ribbons/banks of cloud at several elevations in the morning, some ragged patches possible on lower slopes too, but soon lifting and dissipating. Highest tops likely capped most of the day, then a more extensive layer of cloud arrives with time.
Chance of cloud free summits?
50% early, lowering to 20%
Sunshine and air clarity?
A few glimpses of weak sun early but otherwise overcast. Visibility limited by haze.
How Cold? (at 900m)
6 or 7C, beginning to lower late in the day, by several degrees overnight. Feeling around freezing in early wind.

How windy? (On the summits)
North-northeasterly 25-30mph from dawn. Gradually easing, to 15mph or less by evening, direction becoming variable.
Effect of the wind on you?
Walking inconvenienced in the morning and feeling chilly, effects becoming small with time.
How Wet?
Little rain expected
Some patchy rain affecting mid- and east-Wales in the morning, some risk patches more broadly over Snowdonia NP, but trending widely drier with time.
Cloud on the hills?
Most extensive early, improving tendency
From dawn, cloud may be extensive above 600m, odd lower patches; clearest hills northwest of highest tops. An improving trend is probable, many Snowdonia summits to clear (best northwest); some uncertainty to the south and east.
Chance of cloud free summits?
Rising to 50%
Sunshine and air clarity?
Mostly cloudy though bright breaks, sun breaking out later. Excellent visibility away from cloud/rain.
How Cold? (at 900m)
-1 or 0C from dawn, rising to +1C.
Freezing Level
800-900m, lifting off the summits with time.
Planning Outlook
Thursday into Friday sees a band of rain pass east across most mountains, then a relatively settled weekend for England and Wales, and perhaps east Scotland too. Varying conditions over the next couple of weeks as areas of high pressure build across the British Isles then slip eastwards: dry and bright days with light winds mixed with periods of strengthening south/westerly winds bringing occasional rain from the west. Temperatures will vary, at times lifting just above freezing to high Munro tops, but typically lowering again to high terrain and briefly mid-slopes. Freezing levels will only briefly touch high England and Wales summits, but some frosts into valleys during clear-sky nights. Remaining old snow cover on Scottish mountains stays largely consolidated with little change, any remaining snow in England and Wales will thaw.
