Open-hillside camping looks very good overall around 300 m (97/100). Light winds are expected on open ground, though local shelter and exposure still matter. Little overnight rain is forecast. Forecast models strongly support a good night, but not at the exceptional-certainty threshold. The grade is capped at 97/100.

Warmth planning: As a broad starting point, consider a 2-season bag with an ISO/EN comfort rating at or below about 12°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.

Conditions for exposed scrambling look excellent (100/100). Rock is likely to be mostly dry, though seepage and shaded holds are not resolved. The mapped summit rock is Chalk (Lewes Nodular Chalk Formation). Usually positive where it is rough and dry, but polished limestone can become very slippery when wet and seepage may linger.

The day on the hill

On Coombe Hill: summit wind broadly 10-20 mph, with gusts 15-25 mph at times (a moderate breeze).

Things to watch

Thunder watch from the morning into the afternoon: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops.

If a thunderstorm develops, sudden gusts and heavy rain can change conditions quickly.

Cloud & views

Cloud base around 1500–1800 m in the morning, then around 800–1100 m around midday and 1000–1300 m by late afternoon. The summit is likely to stay mostly clear.

Cloud may hang lower on western slopes and lift somewhat on the eastern side, but local terrain can differ.

Little or no rain is forecast.

The day on the hill

Little rain and limited summit cloud on Coombe Hill: summit wind broadly 10-20 mph, with gusts 15-25 mph at times (a moderate breeze). Patchy mist is possible in sheltered valleys early on.

Cloud & views

Cloud base around 1400–1700 m around midday, lowering to 1200–1500 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. Forecast models disagree on cloud cover.

The surrounding model grid indicates 9.8 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 very good overall around 300 m (88/100). Light winds are expected on open ground, though local shelter and exposure still matter. Little overnight rain is forecast. Some condensation is possible overnight. Forecast models are not closely enough agreed for an exceptional grade. The grade is capped at 88/100.

Warmth planning: As a broad starting point, consider a 3-season bag with an ISO/EN comfort rating at or below about 6°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.

Conditions for exposed scrambling look good (87/100). Likely to stay mostly dry, but patchy rain remains possible and could leave exposed rock damp or slippery. The mapped summit rock is Chalk (Lewes Nodular Chalk Formation). Usually positive where it is rough and dry, but polished limestone can become very slippery when wet and seepage may linger.

Cloud & views

Cloud base around 300–600 m in the morning, lifting to 2900–3200 m around midday. The summit is likely to stay mostly clear.
