Summary for all mountain areas
Early showers in north Scotland and Wales will fade, widely dry and bright conditions for several midday/afternoon hours. Cool-to-chilly, little wind. High cloud builds west, wind and rain arriving to west Scotland afternoon, spreading east and into England and Wales as evening approaches, deteriorating into night.
Headline for Brecon Beacons
Cool and mostly sunny; high cloud builds later, rain around evening
How windy? (On the summits)
Northwesterly around 30mph to start, lessening and shifting westerly 15-20mph, later shifting southwesterly and restrengthening to finish near 30mph, rising further overnight.
Effect of the wind on you?
Fairly small most of the day, though notably blustery in exposure to start, then significantly deteriorating overnight.
How Wet?
Substantially dry during daylight
Some showers drift onto the Cambrians from dawn, a few reaching into the Brecon Beacons, easing for largely dry conditions well into the day. Patchy rain returns from the west around evening, exact timing uncertain, but quickly becoming frequent.
Cloud on the hills?
Early patchy cloud largely clears
Varied banks above 700-800m early, more extensive along coastal Cambrians, lifting and breaking up for little cloud well into the day. Cloud returns to high terrain evening, filling in overnight.
Chance of cloud free summits?
70%
Sunshine and air clarity?
Early patchy cloud will break up for mostly sunny conditions, then high cloud arrives and thickens as afternoon goes. Very good visibility, a little haze mostly towards the Irish Sea.
How Cold? (at 750m)
5 or 6C, rising a degree during daylight, then sharply rising overnight to 10C or higher.

How windy? (On the summits)
Westerly 35-45mph, quite gusty, may lessen somewhat later.
Effect of the wind on you?
Arduous walking, sometimes more challenging with buffeting affecting balance. Significant wind chill.

Some showery rain will drift onto the Cambrian mountains from the Irish Sea, generally light in nature. Rain sometimes spread more broadly across Brecon Beacons, but rainfall amounts to little and some mountains stay dry.
Cloud on the hills?
Largely or entirely clearing
A little ragged cloud here and there on sheltered slopes to start the day, lifting and generally breaking up. A few cloud banks will cling to the high Cambrians and highest Brecon Beacons, but this will ultimately clear.
Chance of cloud free summits?
Rising to 80%
Sunshine and air clarity?
Often sunny, more patchy in the west/around the Cambrians. Good visibility though a haze.
How Cold? (at 750m)
5 or 6C. Feeling like -5 to -8C in direct wind.
Freezing Level
Above the summits.
Planning Outlook
Rain, low cloud and strong upland winds across Britain overnight into Friday morning. Friday and Saturday are windy and showery with bright breaks, a risk of severe gales on many summits. Sunday sees a more settled day as a small ridge of high pressure builds from the west; wind eases, plenty of bright breaks, cool temperatures. Next week sees continued mixed weather: bands of rain coming and going, temperatures similarly fluctuating: generally mild, but sometimes chilly in Scotland with freezing levels lowering onto high Munros where rain turns to snow; any accumulating snow soon thaws. Westerly wind will be dominant, often quite strong, gales at times, but this allows for drier, brighter windows on eastern hill groups between weather systems.
