The day on the hill
Little rain and limited summit cloud on Roseberry Topping: summit wind broadly 5-15 mph, with gusts 10-20 mph at times (light winds).
Cloud & views
Cloud base around 1100–1400 m in the morning, lowering to 900–1200 m around midday and 800–1100 m by late afternoon. The summit is likely to stay mostly clear.
Rain & temperature
Little or no rain is forecast.
Forecast confidence
Cloud height remains uncertain, especially where it is close to summit level.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 7.4 h of sunshine. This is not a forecast of time in sunshine on the summit. Use the cloud and views outlook above for the conditions on this mountain.

Full overnight outlook
Open-hillside camping looks reasonable overall around 300 m (64/100). Light winds are expected on open ground, though local shelter and exposure still matter. A little rain is forecast overnight. Pitches near 300 m may spend part of the night in cloud, bringing damp conditions and poor visibility while cloud is present. Condensation risk is high near 300 m. Ventilation will matter.

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 & scramblingBetaRock may be damp or still drying. Good70/100 View detailsHide details
Full climbing & scrambling outlook
Conditions for exposed scrambling look fair (70/100). Some rock may still be damp or drying, especially on polished slabs and vegetated sections. The mapped summit rock is Sandstone, siltstone and mudstone (Saltwick 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. Representative samples along available mapped routes also include Mudstone, so rock character and wet-weather behaviour may change across the mountain.

The summit type remains the forecast's cautious rock-response reference. Other mapped types show where conditions may behave differently elsewhere on the mountain.

BGS recordOften positive when dry, but smooth, polished or slabby sections can become markedly more slippery when damp.

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.
