Mid Wales and Cambrian Mountains
A poor day on the tops in Mid Wales and the Cambrian Mountains, with many summits in cloud for most of the day.
Sunshine and sky
Extensive cloud. Cloud is likely to remain extensive for much of the day.
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 south-westerly wind of 15–25 mph, gusting 25–35 mph. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Walking impact
Gusts of 25–35 mph will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Ground conditions
The ground is likely to be wet after recent rain.
Rain and showers
Drizzle for much of the day. Rain is possible during the main walking period, but its timing may shift by several hours. The timing may shift by a few hours.
Cloud-free summits
Clear-summit estimate: about 10% early, about 10% around midday and about 10% later.
Cloud and visibility
Expect many summits to be in cloud for most of the day. The cloud base could be as low as 500–800 m early in the morning. In cloud you'll be finding your way without landmarks, so carry navigation you trust and know how to use, with a backup such as a spare battery or a map and compass.
Temperature and wind chill
At around 700 m it will be 10 to 14°C, feeling like 6 to 10°C in the wind.
Freezing level
The freezing level is above the summits.
Daylight
Sunrise 07:34, Sunset 18:27, about 10.9 hours daylight.
Overnight · 17:00–08:00Wild campingBetaNot a night to camp on the open hill anywhere in this area: gusts of about 55 mph and around 16 mm of rain. 9Poor · 600 m View detailsHide details
Full regional overnight outlook
Not a night to camp on the open hill anywhere in this area. Gusts reach about 55 mph around 900 m and nearer 40 mph around 300 m, strong enough to flatten or tear a tent. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. About 16 mm of rain is forecast overnight. Above about 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 9°C at 900 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 very poor (18/100). Rain is likely to leave rock wet. Polished slabs, vegetation and drainage lines may be notably worse. Gusts may reach about 30 mph on exposed ground, making crosswinds an important route consideration. Mapped summit-point geology across the representative hills includes volcanic rock, granite, gneiss or gabbro and sandstone or gritstone. Rock can therefore respond differently to moisture between crags and routes.
Representative summit-point samples across the region; individual crags and routes may differ.

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.
