Clwydian Range and Berwyns
A fine day in the Clwydian Range and the Berwyns: light winds and clear tops for most of the day.
Sunshine and sky
Cloud becoming more extensive. Cloud cover is likely to increase as sunshine becomes less frequent.
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-easterly wind of 10–20 mph, gusting 15–25 mph.
Walking impact
Noticeable on exposed ground, but unlikely to impede most walking.
Rain and showers
Drizzle sets in during the early afternoon.
Cloud-free summits
Clear-summit estimate: about 90% early, about 80% around midday and about 50% later.
Cloud and visibility
The tops should stay mostly clear of cloud. The cloud base could be as low as 700–1000 m in the late afternoon. Mist or fog is possible in some valleys early on. Good spells of sunshine are likely.
Temperature and wind chill
At around 600 m it will be 2 to 6°C, feeling like -2 to 2°C in the wind. Take a hat, gloves, a windproof and a spare warm layer.
Freezing level
The freezing level is close to summit height.
Daylight
Sunrise 07:44, Sunset 18:12, about 10.5 hours daylight.

Full regional overnight outlook
Too windy for an exposed pitch around 900 m on some hills. Lower down, a mixed night to camp, mainly because of the wind. Gusts reach about 35 mph on open ground, which makes for a noisy, testing night even in a good tent. Check the forecast for the hill and height you have in mind, and don't assume lower ground will be sheltered. Some light rain is forecast overnight. The air is damp at every height we checked (300-600 m), so expect heavy condensation. Leave the vents open. Overnight lows of about 5°C at 300 m.

Cloud and terrain vary across the area. Illumination describes the sunlit part of the Moon, not brightness at your pitch.
Overnight window: 18 Oct, 17:00 BST to 19 Oct, 08:00 BST. Approximate open-horizon times; hills can hide the Moon. Still take a headtorch.

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 mixed (54/100). 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.
