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.
Tuesday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Moderate rain
Steady rain fairly persistent, occasionally heavy, rather wet underfoot.
Poor visibility
Very murky conditions, the mountains shrouded in fog, making navigation challenging. Map and compass essential.
Cool
Temperatures above freezing but typically no higher than +5C over the tops - if exposed to brisk winds will feel sub-zero. May not feel cold when climbing, but noticeably cold when stationary. Carry suitable clothing.

How windy? (On the summits)
Easterly or variable, 20 to 35mph, locally may be very gusty, mainly mid-Wales, in places downslope to west.

Locally very varied, but possible sudden buffeting making walking arduous in places not just on higher terrain.

Periods of rain
Uncertain progress of a slow-moving front over Wales, may give several hours of rain, some heavier bursts from elevated cloud layers.
Cloud on the hills?
Risk extensive
Risk of low cloud shrouding many hills for periods, most persistent eastern areas. May vary during the day, filling in extensively around rain, but some periods where cloud largely above hills, best breaks in west.
Chance of cloud free summits?
40%

Rare weak sun due to high cloud layers, mostly overcast and dull. Hazy.

Planning Outlook
High pressure to the north and a slow-moving area of low pressure circulating to the south during midweek. Scattered showers possible for the Highlands, but a lot of dry weather - warmest and clearest in the west. Powerful easterly winds will be very gusty by Thursday into early Friday, especially southern Scotland and northern England, then easing. A front brings a risk of persistent rain for Wales on Thursday. Slow-moving weather patterns are likely to continue onward into the Bank Holiday weekend, giving considerable uncertainty of local day-to-day detail, but most likely the wind often light and fairly warm overall. A good amount of dry and bright weather, but risk of locally thundery showers forming.
