The day on the hill

Mostly dry with limited summit cloud on Silver How: summit wind broadly 10-25 mph, with gusts 20-30 mph at times (a fresh breeze).

Cloud & views

Cloud base mostly around 600–900 m through daylight. The summit is likely to stay mostly clear.

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 at times. The forecast total is up to around 2 mm, but local amounts will vary.

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.

Sunshine context Model-grid estimate, not summit sunshine

Full climbing & scrambling outlook

Conditions for exposed scrambling look mixed (48/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Dacitic lapilli-tuff (Lincomb Tarns Tuff Formation). Often grippy when dry, but volcanic rocks vary widely; wet lichen, smooth holds and local seepage can still make them slippery. Representative samples along available mapped routes also include Andesite, Volcaniclastic rocks (both pyroclastic and reworked volcanic rocks and 1 other mapped type, so rock character and wet-weather behaviour may change across the mountain.

The day on the hill

On Silver How: summit wind broadly 10-30 mph, with gusts 25-35 mph at times (a fresh breeze). Visibility may drop briefly in showers.

Cloud & views

Cloud base around 600–900 m in the morning, lifting to 1000–1300 m around midday and 1600–1900 m by late afternoon. The summit is likely to stay mostly clear.

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.

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 models differ on summit wind strength: around 17-26 mph at walker height, with gusts 24-37 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Exposed tops may feel chilly in the wind.

A windproof layer will help, with an extra warm layer for stops. If clothing gets wet, you can cool more quickly.

Keep a dry warm layer protected. Forecast models differ on whether meaningful rain reaches the hills during the morning.

Cloud-free timing: Around 75% early, improving to around 95% later.

The day on the hill

On Silver How: summit wind broadly 15-30 mph, with gusts 30-40 mph at times (strong winds). Patchy mist is possible in sheltered valleys early on.

Cloud & views

Cloud base around 1200–1500 m in the morning, lifting to 1800–2100 m around midday. The summit is likely to stay mostly clear.

Rain & temperature

Little or no rain is forecast. Forecast models differ on summit wind strength: around 18-32 mph at walker height, with gusts 26-44 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Exposed tops may feel chilly in the wind.

A windproof layer will help, with an extra warm layer for stops. Buffeting may affect balance on exposed ground, particularly near ridges and edges.

Summit wind could be roughly 18-32 mph, which changes how difficult exposed walking may feel.

The mapped summit rock is Dacitic lapilli-tuff (Lincomb Tarns Tuff Formation). Often grippy when dry, but volcanic rocks vary widely; wet lichen, smooth holds and local seepage can still make them slippery. Representative samples along available mapped routes also include Andesite, Volcaniclastic rocks (both pyroclastic and reworked volcanic rocks and 1 other mapped type, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 35 mph. Crosswinds can make exposed ridges substantially more serious.

The day on the hill

A wet day on Silver How: summit wind broadly 10-30 mph, with gusts 30-40 mph at times (strong winds).

Wind & exposure

Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops.

Cloud & views

Cloud base mostly around 500–800 m through daylight. The summit is likely to stay mostly clear.

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. Drizzle is forecast for much of the day.

The forecast total is around 5-10 mm, but local amounts will vary. Forecast models differ on summit wind strength: around 20-36 mph at walker height, with gusts 28-50 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Exposed tops may feel chilly in the wind.

A windproof layer will help, with an extra warm layer for stops. If clothing gets wet, you can cool more quickly.

Keep a dry warm layer protected. Buffeting may affect balance on exposed ground, particularly near ridges and edges.

Rain timing may shift by several hours, which could change how much of the main walking period stays dry.

Sunshine context Model-grid estimate, not summit sunshine

The day on the hill

Little rain and limited summit cloud on Silver How: summit wind broadly 10-25 mph, with gusts 25-35 mph at times (a fresh breeze). Patchy mist is possible in sheltered valleys early on.

Cloud & views

Cloud base around 600–900 m in the morning, lifting to 800–1100 m around midday. The summit is likely to stay mostly clear.

Cloud-height uncertainty could put the summit in or out of cloud. Clear spells may be difficult to time.

Rain & temperature

Little or no rain is forecast.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Exposed tops may feel chilly in the wind.

A windproof layer will help, with an extra warm layer for stops. Rain could reach the main walking period or hold off until later. Forecast models disagree on the timing.

Cloud-free timing: Around 75% early, improving to around 95% later.

Open-hillside camping looks reasonable overall around 300 m (64/100). It may be breezy on open ground, with gusts near 25 mph. Around 2.4 mm is forecast, with rain liable to affect both pitching and packing up. Condensation risk is high near 300 m, so a wet pack-up is possible. Ventilation will matter.

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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look mixed (55/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Dacitic lapilli-tuff (Lincomb Tarns Tuff Formation). Often grippy when dry, but volcanic rocks vary widely; wet lichen, smooth holds and local seepage can still make them slippery. Representative samples along available mapped routes also include Andesite, Volcaniclastic rocks (both pyroclastic and reworked volcanic rocks and 1 other mapped type, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 30 mph. Crosswinds can make exposed ridges substantially more serious.

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.
