Summary for all mountain areas
Westerly gales across many mountains will make walking challenging and bring significant chill factor; air temperature close to freezing point on highest summits. Rain most persistent in western Scotland, snow falling on high tops. Frequent showery rain for northwest England, fewer showers south across Wales.
Headline for Brecon Beacons
Windy, up to gales on high tops; occasional showers.
How windy? (On the summits)
Westerly 30 to 40mph, quite gusty, tending to drop somewhat to 25-30mph afternoon. Gradually lowering further onward into night.
Effect of the wind on you?
Strenuous to arduous walking, in places buffeting affecting balance. Considerable wind chill.
How Wet?
A little rain mostly west
Some showery rain will drift onto the Cambrian mountains from the Irish Sea, generally light in nature. Rain sometimes spreads more broadly across Brecon Beacons, but rainfall amounts to little and some eastern mountains more often 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 often above tops.
Chance of cloud free summits?
Rising to 80%
Sunshine and air clarity?
Sun breaking through most often south and east, cloudier in the west and around the Cambrians. Good visibility though a haze.
How Cold? (at 750m)
5 or 6C. Feeling like -5 to -8C in direct wind.

How windy? (On the summits)
South-southwesterly 20 to 30mph, then late in day likely to increase, to 50mph most likely after dark.
Effect of the wind on you?
Fairly small, but blustery around higher exposed terrain, likely to deteriorate onward into evening-night.

Generally damp, some steady rain
Rain and drizzle most persistent over west and southwest-facing hills, some steady or heavier rain more widely early and late. Patchier smaller amounts toward eastern mid-Wales, sometimes easing off.
Cloud on the hills?
Extensive
Shrouding most hills all day, from lower elevations much of Brecon Beacons and western Cambrians, rarely above 400-500m inland. Perhaps an improvement afternoon.
Chance of cloud free summits?
10%
Sunshine and air clarity?
Overcast, dull or murky. Local brighter moments east-mid Wales and during afternoon.

11 to 13C, little change day and night. Feeling like 3C if in stronger wind.

Planning Outlook
After a fine but cool day on Sunday, damp and mild southwesterly air moves back across the country into Monday. Southwesterly winds strengthen late Monday to widely gale-force over the hills, heavier rain likely into early Tuesday, followed by showers and a slight drop of temperature. Very unsettled west-southwesterlies continue into midweek - sustained mountain gales, possibly stormy at times and spells of heavy rain for all areas. A changeable westerly theme likely continues beyond mid-month - occasional windows of drier weather, but more often windy with rain or showers coming in from the Atlantic, sometimes cold enough to fall as snow on Scottish high tops.
