Brecon Beacons
Includes all higher summits in the southern half of Wales: the Bannau Brycheiniog / Brecon Beacons National Park, southern Cambrian Mountains and highest Preseli hills.
Sunday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Frequent or persistent rain
Steady rain fairly persistent, occasionally heavy, rather wet underfoot.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
Chilly
Air temperature typically 0 to 5C on higher summits. Feeling distinctly chilly on tops when stationary or where exposed to wind. Take appropriate layers.

Summary for all mountain areas
Blustery for most, gales in Scotland which will be severe on high tops early. Continued snow and local whiteout conditions on high terrain in east Scotland, snowdrifts build here. Often raining over the Pennines and south Wales, more intermittent in north Wales and Lakeland (sleet or snow on high summits).
Headline for Brecon Beacons
Breezy; regularly raining and often foggy
How windy? (On the summits)
Southeasterly, speed may vary, mostly 25 to 30mph, locally stronger gusts around high tops. Speeds may notably ease in the south/east later in the day, though remaining variable.
Effect of the wind on you?
Blustery over most high terrain, gustier areas affecting comfortable walking. Marked wind chill in exposure on tops.
How Wet?
Frequent or persistent rain
Rain on and off most of the day, most frequent on south and eastern hills where may be steady for hours at a time; patchier western mid-Wales.
Cloud on the hills?
Extensive
Covering much of the Brecon Beacons and eastern mid-Wales all day, often to mid-slopes. Higher bases westwards, rare breaks above 600-700m.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Largely cloudy, a haze building. Poor visibility over most hills in fog and rain.
How Cold? (at 750m)
1 or 2C. Feeling like -7 to -10C in the wind.

Fairly extensive
Some higher breaks north of the high Brecon Beacons with time, though summits are unlikely to clear for any period of time.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Mostly cloudy, a few bright moments may break out afternoon. Visibility often very poor in precipitation, though local improvements afternoon.

Just touching the highest summits at daybreak, lifting above the summits.
Planning Outlook
An unsettled week ahead: a dominance of low pressure will bring periods of wet weather and gales (at times severe), to all areas. Winds will be predominantly east-southeasterly, particularly in Scotland, maintaining the cold air with freezing levels consistently to middle or lower slopes - wind chills will be severe. A near-term risk of flooding in the eastern highlands. Wind direction will be more variable in England and Wales, at times shifting south-southwesterly and drawing in milder air, brining freezing levels to upper slopes or even above the high summits. Low cloud often covering many hills with only local sunny breaks here and there.
