The day on the hill
On Round Hill: summit wind broadly 5-20 mph, with gusts 15-25 mph at times (a moderate breeze). Hill cloud may make navigation difficult, with very poor visibility in wetter spells.
Things to watch
Possible spate risk early in the day and into the afternoon, with forecast rain and subsequent runoff. Timings are approximate, not a guarantee of safe crossings afterwards. Burns and unbridged crossings may rise quickly. Turn back if a crossing looks unsafe.
Cloud & views
Cloud base around 600–900 m through the morning, lifting to 1500–1800 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from late afternoon into the evening.
Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.
Cloud may hang lower on northwestern slopes and lift somewhat on the southeastern side, but local terrain can differ. Sunny spells are possible away from summit cloud, but may not reach the top while it is in cloud.
Rain & temperature
Rain and drizzle are forecast at times, with some passing showers too. The forecast total is around 5-10 mm, but local amounts will vary.
Forecast confidence
Cloud height remains uncertain, especially where it is close to summit level. Rain timing may shift by several hours, which could change how much of the main walking period stays dry.
Cloud-free timing: Around 40% early, improving to around 95% later.
Sunshine context Model-grid estimate, not summit sunshine
The surrounding model grid indicates 1.7 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.

Warmth planning: As a broad starting point, consider a 3-season bag with an ISO/EN comfort rating at or below about 4°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. Poor0/100 View detailsHide details
Full climbing & scrambling outlook
Conditions for exposed scrambling look very poor (0/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Mudstone, sandstone and limestone (Stainmore Formation). Usually positive where it is rough and dry, but polished limestone can become very slippery when wet and seepage may linger. 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.
