Clwydian Range and Berwyns
A poor day on the tops in the Clwydian Range and the Berwyns, with burns likely to be in spate and drizzle clearing by early afternoon.
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 westerly wind of 15–25 mph, gusting 25–35 mph. Gusts like that will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Walking impact
Gusts of 25–35 mph will be noticeable on ridges and open tops, and you will chill quickly when you stop.
Ground conditions
The ground is likely to be wet after recent rain.
Spate risk
High spate risk based on recent and forecast rainfall. Burns and unbridged crossings may become difficult or impassable. Timing and severity can vary between catchments. Check the peak forecast for the separate rain/runoff periods. Turn back if a crossing looks unsafe.
Rain and showers
Drizzle at first, clearing by early afternoon. Expect 2–5 mm in total. Rain is possible during the morning and afternoon, but forecast models disagree on whether it will fall.
Cloud-free summits
Clear-summit estimate: about 15% early, about 25% around midday and about 20% later.
Cloud and visibility
Expect many summits to be in cloud for most of the day. The cloud base lifts through the day. The cloud base could be as low as 200–500 m first thing. 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. Some forecast models are much cloudier overhead. That may limit sunshine without putting the summits in cloud. Mist or fog is possible in some valleys early on.
Temperature and wind chill
At around 600 m it will be 2 to 6°C, feeling like -6 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 07:40, Sunset 16:17, about 8.6 hours daylight.

Full regional overnight outlook
Across these hills, a mixed night to camp, mainly because of the wind. Gusts reach about 30 mph on open ground, so peg out well and use the guylines. Look for shelter from the west. A little 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. 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 600 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 (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.
