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.
Today'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.

Fairly extensive
Covering the hills fairly widely above 600m, some lower bases on eastern aspects. Local breaks forming higher up west Wales.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Largely cloudy, dull in east. Visibility mostly poor, local improvements further west.
How Cold? (at 750m)
0 or 1C. Directly in the wind feeling like -12 to -15C.

Planning Outlook
Sustained gale force easterlies over most mountains into the weekend, powerful gusts downslope toward west; severe chill factor. Colder air and lowering freezing level moves into Scotland on Friday, much mountain terrain then frozen into the weekend and early next week. Substantial snowfalls over eastern Scottish hills later this week, drier to the west. Dropping just below freezing on high tops in England and Wales - a mix of rain and high level snow, turning colder further south over the weekend, with freezing level dropping to the southern Pennines summits next week. Circulating low pressure and cold air into next week, with further snowfalls likely. Lower wind speeds early in the new week, but then likely increasing E-SE'ly again.
