Headline for Brecon Beacons

Patchy cloud and rain, deteriorating with strengthening wind

How windy? (On the summits)

Southerly 20-30mph, at times up to 35mph on westernmost hills towards Pembrokeshire. Trending southeasterly and broadly rising to 35-40mph for several afternoon hours, then easing into night and shifting southwesterly.

Effect of the wind on you?

Walking strenuous-to-arduous most of the day; balance will be challenged in exposure. Considerable wind chill.

How Wet?

Rain increasingly widespread afternoon

Patchy rain onto southern slopes through the morning with drizzle over the high tops. A broader area of rain sweeps in from the southwest afternoon, becoming persistent and widespread for several hours, possibly into nighttime.

Cloud on the hills?

Extensive high tops and southern slopes

Fairly extensive above 600-700m most of the day with fog to lower elevations on southern slopes. Some higher breaks may occur in the north through the morning, then bases drop further with cloud becoming widely extensive as rain arrives.

Chance of cloud free summits?

30%, dropping to 10%

Sunshine and air clarity?

Little sunshine, if any. Excellent visibility, turning poor as rain sets in.

Planning Outlook

A brief brighter spell on Saturday, but otherwise staying mild with low cloud, drizzle and rain at times well into next week. Areas northeast of major hill groups seeing least rain and highest cloud breaks, though high summits will struggle to clear the fog as the air will remain generally humid. Southerly winds of varied strengths, sometimes more blustery, approaching gale-force in exposed western areas. As the following weekend approaches, indications of northeasterly winds developing for Scotland, bringing drier weather to the west, and potentially much colder with time. England & Wales may remain frequently wet under slow-moving low pressure - uncertainty over timing and locations of the coldest conditions.
