Headline for Brecon Beacons
Patchy rain, fog, and strong wind most of the day, gales for a time
How windy? (On the summits)
Southerly 25-35mph from dawn, strongest west with powerful gusts over tops and downslope, soon strengthening to 35-45mph widely with gusts approaching 50mph for a time. May ease somewhat later afternoon, but restrengthening into evening.
Effect of the wind on you?
Blustery in exposure from dawn and walking soon becomes arduous with considerable buffeting and notable wind chill despite mild temperatures. Walking challenging during strongest wind.
How Wet?
Patchy rain, more frequent for a few hours
A risk of patchy rain from dawn, mostly coming from the south and rainfall totals generally low. Rain may be more frequent with heavier moments late morning through midday, but patcher again afternoon and may cease for a time, though remaining drizzly on highest tops. Returning more frequently into night.
Cloud on the hills?
Soon extensive
Before dawn, just a few patches of cloud at various elevations, but a sheet of cloud soon descending to the high tops around dawn, bases soon lowering, patchy at first, but gradually extensive to middle slopes and later to 400m or lower; higher bases northern slopes. A brief small improvement late afternoon.
Chance of cloud free summits?
Soon almost nil
Sunshine and air clarity?
Some weak sun possible just at dawn, but cloud soon building, becoming overcast and often dull. Visibility generally poor due to cloud and fog.
How Cold? (at 750m)
3C rising to 7C, staying elevated into night and reaching 8C. Feeling colder later in day as wind increases.

Southwesterly 20-25mph, up to 30mph early morning.

Drizzly over high terrain much of morning. Drizzle will ease, then scattered light showers will occur here and there through afternoon.
Cloud on the hills?
Lifting largely above summits
Most terrain above 700m in cloud from dawn, to 500m south and western slopes, bases rising to mostly just caps on the high tops by midday, the summits often clear afternoon, only odd caps returning.
Chance of cloud free summits?
30% rising to 70%
Sunshine and air clarity?
Sunshine increasingly breaking out to a patchwork afternoon, slow to break in the west. Visibility becoming very good.
How Cold? (at 750m)
5C, rising to 6C, locally 7C eastern hills. Feeling as cold as -5C in early wind.

Planning Outlook
Milder from Wednesday into the weekend, but Scottish high tops below freezing at times, locally lower in the northwest. Unsettled conditions in the immediate near-term with showers (sometimes heavy with hail and lightning), occasionally more persistent rain, accompanied by often gusty winds, gales over mountains for periods, but also brighter spells between rain. With spring sunshine, temperatures will tend to rise several degrees during daylight, often becoming warm in the valleys; slopes north of major hill groups often milder. Saturday sees continued showers, mostly north and west, but higher pressure gradually builds through late weekend into early next week, bringing fewer showers and lighter winds; chilly overnight, but fairly mild spring days. Confidence is low regarding how long high pressure will establish.
