Summary for all mountain areas
A largely dry day for the Highlands, light winds inland and north, some sun, but a layer of cloud increasingly covers the sky from the south, later some rain moving into coastal areas. A little rain for northern England and Wales, locally risk of a heavier burst of rain forming. Gusty southerly winds particularly Wales.
Headline for Brecon Beacons
Gusty wind. A little early rain, possible fog later SW.
How windy? (On the summits)
South-southeasterly 20-25mph most of the day, some gusts over 30mph around high tops in morning, occasionally through the day, speeds varying; trending west-southwesterly tops evening.
Effect of the wind on you?
Blustery over the tops early with strenuous walking; effect easing, but ease of walking often affected.
How Wet?
Some patchy rain
A band of patchy rain affects the hills for a few early hours, this soon passing to the northeast for a largely dry day. Some drizzle later in southwest areas.
Cloud on the hills?
Mostly little, some low cloud later southwest
Patchy banks of cloud early at various heights, mostly southern slopes and many clear areas too. Afternoon onward, low cloud or fog over the sea tending to push inland from southwest, later may cover more southwestern hills.
Chance of cloud free summits?
80%, dropping later southwest areas.
Sunshine and air clarity?
Some weak sun through high cloud at times, perhaps briefly more sunny. Good visibility, though reduced in morning rain, some haze, may become misty from southwest afternoon.
How Cold? (at 750m)
12 or 13C, rising up to 15C many hills, feeling quite humid. Feeling cooler in exposure to the gusty wind, nearer 5C on tops.

How windy? (On the summits)
Southwesterly 25 to 30mph, gusty around higher tops and on some eastern downslopes.
Effect of the wind on you?
Blustery over the hills, strenuous walking in exposure on higher slopes, starting to affect balance in places on tops.
How Wet?
Rain may persist, then fading
A mix of rain, drizzle and some showery moments; the most frequent rain typically west and southwest of Brecon, risk persistently wet over several hours. Tending to fade through afternoon.
Cloud on the hills?
Extensive, may improve afternoon
Blanket cloud across the hills around rain, from lower slopes upward in areas south and west of Brecon at least in morning, but likely to persistent all day over tops. Lifting to 600m in east, some breaks form higher in afternoon
Chance of cloud free summits?
20%
Sunshine and air clarity?
Largely cloudy, some sun may break through later mainly east. Hazy much of day southwest areas, misty widely around rain, then visibility improves during afternoon, to be very good in east.
How Cold? (at 750m)
10 or 11C, little change all day. Feeling near to freezing directly in wind.
Freezing Level
Above the summits.
Planning Outlook
A variable southwesterly will dominate through mid to late this week - windy at times with periods of rain, drizzle and low cloud most persistent in the west. Pressure generally trending higher from the south by the weekend, though into Saturday at least a damp westerly likely prevails into western Scotland. Warmest in England and Wales, but cooler in Scotland as low pressure to the northwest recycles air from the north Atlantic back onto the Munros. A window of drier and warmer weather is favoured into early the following week (22nd June), though a mixed Atlantic pattern may linger near to northwest Scotland in the longer range.
