Clwydian Range and Berwyns
A good day in the Clwydian Range and the Berwyns, though expect rain arriving mid-morning.
Sunshine and sky
Limited sunny breaks. Any sunshine is likely to come through limited breaks.
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 15–25 mph, gusting 20–30 mph. A wind like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Walking impact
A steady wind of 15–25 mph will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Rain and showers
Rain arrives mid-morning. Expect 2–5 mm in total. Drizzle is possible on some hills.
Cloud-free summits
Clear-summit estimate: about 20% early, about 90% around midday and about 90% later.
Cloud and visibility
Cloud on the tops early should lift off them by mid-morning. The cloud base could be as low as 600–600 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.
Temperature and wind chill
At around 600 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 07:26, Sunset 18:35, about 11.2 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 35 mm of 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 300 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 (14/100). 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 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.
