Clwydian Range and Berwyns
A good day in the Clwydian Range and the Berwyns, though expect snow on the tops.
Sunshine and sky
Less sunshine later. Sunshine is indicated less often later in 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 (600 m)
At around 600 m, expect a north-westerly wind of 10–20 mph, gusting 15–25 mph.
Walking impact
Noticeable on exposed ground, but unlikely to impede most walking.
Rain and showers
Dry through the daylight hours, but snow arrives after dark. Rain is possible during the afternoon, but forecast models disagree on whether it will fall. On some hills, snow is possible on the tops. Snow is forecast on some higher tops in the morning. The air freezing level is around 500 m above sea level. Snow can fall below this, but its lower limit is uncertain.
Cloud-free summits
Clear-summit estimate: about 10% early, about 70% around midday and about 75% later.
Cloud and visibility
Any early cloud on the tops should clear soon after dawn. The cloud base could be as low as 400–700 m early in the morning. Some forecast models are much cloudier overhead. That may limit sunshine without putting the summits in cloud. The air should be clear, so expect far-reaching views whenever the tops come out of the cloud.
Temperature and wind chill
At around 600 m it will be -2 to 2°C, feeling like -8 to -4°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 around 400–700 m, so it will be below freezing on the tops.
Daylight
Sunrise 07:38, Sunset 16:18, about 8.7 hours daylight.

Full regional overnight outlook
Not a night to camp on the open hill anywhere in this area. Gusts reach about 50 mph on open ground, enough to damage a tent on open ground. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. About 22 mm of rain is forecast overnight. At every height we checked (300-600 m) you'd likely be in cloud for part of the night: damp, and hard to find your way if you need to move. A frost up around 600 m, down to about -2°C.

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 (0/100). Rain is likely to leave rock wet. Polished slabs, vegetation and drainage lines may be notably worse. Mapped summit-point geology across the representative hills includes slate or mudstone and volcanic rock. 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.
