Clwydian Range and Berwyns
A mixed day in the Clwydian Range and the Berwyns, with cloud coming down onto the tops.
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 (600 m)
At around 600 m, expect a westerly wind of 5–15 mph, gusting 10–20 mph.
Walking impact
Little effect on walking, although exposed tops may still feel chilly.
Rain and showers
Drizzle sets in mid-afternoon. Rain is possible during the morning, but forecast models disagree on whether it will fall. Rain is possible during the main walking period, but its timing may shift by several hours. The timing may shift by a few hours. Visibility may drop briefly in showers in parts of the area.
Cloud-free summits
Clear-summit estimate: about 55% early, about 20% around midday and about 10% later.
Cloud and visibility
The tops start clear, but the cloud comes down onto them around midday. The cloud base could be as low as 300–600 m in the early afternoon. 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 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 07:36, Sunset 16:19, about 8.7 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. About 7 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. A frost at every height we checked (300-600 m), down to about -1°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. Gusts may reach about 35 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.
