Mid Wales and Cambrian Mountains
A poor day on the tops in Mid Wales and the Cambrian Mountains, with a blustery wind and drizzle clearing by mid-afternoon.
Sunshine and sky
Sunshine varies by period. Sunshine amounts vary between the morning, midday and later periods.
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 an easterly wind of 20–30 mph, gusting 30–40 mph. Gusts like that are strong enough to make walking into it hard work, with buffeting on ridges and edges.
Walking impact
Gusts of 30–40 mph are strong enough to make walking into it hard work, with buffeting on ridges and edges.
Rain and showers
Drizzle at first, clearing by mid-afternoon. Expect 2–5 mm in total. 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 35% early, about 30% around midday and about 55% later.
Cloud and visibility
The tops are likely to drift in and out of cloud, with the best chance of clear tops mid-afternoon. The cloud base could be as low as 600–700 m mid-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 4 to 8°C, feeling like -2 to 2°C in the wind. Take a hat, gloves, a windproof and a spare warm layer. Pack waterproofs too, and keep a warm layer dry in your pack.
Freezing level
The freezing level is above the summits.
Daylight
Sunrise 07:46, Sunset 18:11, about 10.4 hours daylight.
Differences across the area
More sunshine is likely around the western hills than the eastern hills. This is a broad-area estimate, not sunshine on every summit.

Full regional overnight outlook
Across these hills, a mixed night to camp, mainly because of the wind. Gusts reach about 35 mph around 900 m and nearer 25 mph around 300 m, so peg out well and use the guylines. Look for shelter from the southeast. Some light rain is forecast overnight. Up around 900 m you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. The air is damp at every height we checked (300-900 m), so expect heavy condensation. Leave the vents open. A cold night, down to about 3°C around 900 m.

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 (4/100). Rain is likely to leave rock wet. Polished slabs, vegetation and drainage lines may be notably worse. Gusts may reach about 40 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.
