The day on the hill
Frequent summit cloud on Combe Head: summit wind broadly 10-25 mph, with gusts 20-30 mph at times (a moderate breeze). Hill cloud may make navigation difficult, with very poor visibility in wetter spells.
Cloud & views
Cloud base mostly around 600–900 m through daylight. Summit cloud is likely, but brief clear spells remain possible if the cloud sits higher than expected.
Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.
Cloud may hang lower on western slopes and lift somewhat on the eastern side, but local terrain can differ. Very little direct sunshine is likely, with extensive cloud.
Drizzle is forecast for much of the day. The forecast total is around 2-5 mm, but local amounts will vary.
Rain & temperature
The ground is likely to be wet after recent rain.
Forecast confidence
Cloud height remains uncertain, especially where it is close to summit level. Cloud-height uncertainty could put the summit in or out of cloud, even where forecasts agree on the wider cloud cover.

Full overnight outlook
Open-hillside camping looks reasonable overall around 600 m (64/100). It may be breezy on open ground, with gusts near 20 mph. Around 1.2 mm is forecast, including rain around pack-up. Condensation risk is high near 300 and 600 m, so a wet pack-up is possible. Ventilation will matter.

Extensive cloud may limit moonlight. Illumination describes the sunlit part of the Moon, not brightness at your pitch.

Warmth planning: As a broad starting point, consider a 2-season bag with an ISO/EN comfort rating at or below about 10°C. Allow more margin if you sleep cold or expect fatigue, and use an adequate insulated mat. Dampness is possible, so keep the sleep system dry and ensure its insulation remains effective if damp.
Open-hillside reference. A sheltered pitch may be calmer; cols and ridges may be much windier. Tent design and the exact pitch still matter. Read about sleeping-bag comfort ratings, pitching in strong winds or using the wild-camping forecast.

Daytime · exposed rockClimbing & scramblingBetaWet rock is likely. Poor18/100 View detailsHide details
Full climbing & scrambling outlook
Conditions for exposed scrambling look very poor (18/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Volcaniclastic rocks (both pyroclastic and reworked volcanic rocks (Seathwaite Fell Sandstone Formation). Usually rough and grippy when dry. Damp sandstone and gritstone can feel greasy, and saturated sandstone may be weakened, so let the rock dry fully. Cloud may also make route-finding and retreat harder.

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.
