Bannau Brycheiniog (Brecon Beacons)
A mixed day in Bannau Brycheiniog (Brecon Beacons), with a blustery wind.
Sunshine and sky
Sunshine through the day. The time blocks show where the model places the brighter spells.
These are direct modelled sunshine hours during daylight, not the probability of sunshine. Cloud cover and summit cloud are assessed separately in the forecast above. The regional median prevents one unusually bright or dull summit cell defining the whole area.
Overnight forecast: 17:00–08:00 (UK local time), in Wild camping below.
High-ground wind (700 m)
At around 700 m, expect a north-westerly wind of 25–35 mph, gusting 35–45 mph. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges.
Walking impact
Gusts of 35–45 mph are strong enough to make walking into it hard work, with buffeting on ridges and edges.
Ground conditions
The ground is likely to be wet after recent rain.
Rain and showers
It should stay dry.
Cloud-free summits
Clear-summit estimate: about 30% early, about 90% around midday and about 90% later.
Cloud and visibility
Any early cloud on the tops should clear soon after dawn. The cloud base could be as low as 500–800 m early in the morning. Some forecast models are much cloudier overhead. That may limit sunshine without putting the summits in cloud. It will look largely cloudy overhead, but that cloud should mostly stay above the tops. The air should be clear, so expect far-reaching views as long as the tops stay clear.
Temperature and wind chill
At around 700 m it will be 4 to 8°C, feeling like -4 to 0°C in the wind. Take a hat, gloves, a windproof and a spare warm layer.
Freezing level
The freezing level is above the summits.
Daylight
Sunrise 07:29, Sunset 18:31, about 11.1 hours daylight.

Full regional overnight outlook
Across these hills, a mixed night to camp. Gusts reach about 30 mph on open ground, so peg out well and use the guylines. Look for shelter from the west. A little rain is forecast overnight. Up around 600 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. Overnight lows of about 6°C at 600 m. The moon won't be up after dark, so there will be no moonlight.

Regional climbing & scrambling outlook
A broad guide to dampness and exposed rock across the area, not a forecast for every crag. Lower, sheltered crags and individual rock types may behave differently.
Conditions for exposed scrambling across the area look poor (29/100). Some rock may remain damp or incompletely dried, especially in shade and seepage lines. Gusts may reach about 40 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes sandstone or gritstone. Rock can therefore respond differently to moisture between crags and routes.

Recommended kit for this dayWeather-aware packing prompts, plus your core hillwalking kitView kit
For a day hillwalk, not a complete route-specific checklist. Carry navigation and backup you can use, warm and waterproof layers, suitable footwear, food and water, a headtorch, emergency shelter, first aid and a way to call for help. Snow, ice, technical terrain and overnight trips need additional equipment and skills.
