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.
Friday'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.

Chance of cloud free summits?
10%, rising to 50% late afternoon.
Sunshine and air clarity?
Overcast and dull with poor visibility. Beginning to improve afternoon, very good visibility for a few hours up to sunset.

Planning Outlook
Changeable westerlies prevail onward into early next week, continuing gales over most high terrain. Below freezing on Scottish mountains above 700-800m into Monday with snow showers; higher freezing level further south, above the tops in Wales with mostly drizzly rain here. Milder air lifts above freezing to all tops into Tuesday with low cloud, drizzle and rain, most persistent west-northwest Scotland. Mixed conditions likely continue, but some windows of better weather mid-late in the week - temperatures vary above and just below freezing on Scottish tops. Potential for cold conditions again early April, but drier conditions possibly more common by then.
