The day on the hill

Frequent summit cloud on Nethermost Pike: summit wind broadly 10-25 mph, with gusts 25-35 mph at times (a fresh breeze).

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. Any sunshine may be confined to lower ground or breaks away from the summit.

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

Forecast models differ on summit wind strength: around 18-26 mph at walker height, with gusts 26-36 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. 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

The surrounding model grid indicates Less than 1 hour 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.

Cloud may obscure this summit even while the surrounding model grid indicates sunshine. The low cloud-free summit estimate is a reason to be cautious about expecting views.

Full overnight outlook

Open-hillside camping looks reasonable overall around 600 m (64/100). It may be breezy on open ground, with gusts near 25 mph. Peak gusts range from about 20 mph at 300 m to 25 mph at 900 m. A little rain may coincide with pitching or packing up. Pitches near 900 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, 600 and 900 m. Ventilation will matter. The coldest temperature falls from about 12.6°C at 300 m to 10.8°C at 900 m.

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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look very poor (12/100). 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 (Deepdale 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. Representative samples along available mapped routes also include Lapilli-tuff, Andesite and 3 other mapped types, so rock character and wet-weather behaviour may change across the mountain. Cloud may also make route-finding and retreat harder.

Full overnight outlook

Open-hillside camping looks mixed overall around 600 m (59/100). A lower pitch near 300 m looks more comfortable. Conditions are less suitable by 900 m. Open-ground gusts may reach about 35 mph. Seek meaningful shelter. Peak gusts range from about 25 mph at 300 m to 35 mph at 900 m. Wind direction may change substantially during the night. Shelter that works at dusk may be less effective later. Around 3.1 mm is forecast, with rain liable to affect both pitching and packing up. Pitches near 900 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, 600 and 900 m. Ventilation will matter. The coldest temperature falls from about 9.2°C at 300 m to 6.8°C at 900 m.

The day on the hill

On Nethermost Pike: summit wind broadly 10-30 mph, with gusts 30-40 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 top is likely to drift in and out of cloud, with the best chance of a view from around midday 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 models differ on summit wind strength: around 18-27 mph at walker height, with gusts 25-38 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 20% early, improving to around 95% later.

The day on the hill

On Nethermost Pike: 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. Cold on exposed tops: air temperature broadly 2 to 6°C, feeling around 0 to 4°C in the wind.

Forecast models differ on summit wind strength: around 18-32 mph at walker height, with gusts 26-45 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. 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.

Full overnight outlook

Exposed camping is not recommended near 900 m: gusts may reach about 45 mph. Sustained winds may reach about 30 mph at times. Lower sheltered ground may be less exposed, but this forecast does not confirm a suitable pitch or a safe approach. Check its overnight conditions separately. Open-hillside camping looks poor overall around 600 m (39/100). Peak gusts range from about 30 mph at 300 m to 45 mph at 900 m. A little rain may coincide with pitching or packing up. Pitches near 600 and 900 m may spend part of the night in cloud, bringing damp conditions and poor visibility while cloud is present. Condensation risk is high near 600 m. Ventilation will matter. The coldest temperature falls from about 9.7°C at 300 m to 7.2°C at 900 m.

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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look fair (60/100). Some rock may still be damp or drying, especially on polished slabs and vegetated sections. The mapped summit rock is Volcaniclastic rocks (both pyroclastic and reworked volcanic rocks (Deepdale 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. Representative samples along available mapped routes also include Lapilli-tuff, Andesite and 3 other mapped types, 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 with extensive summit cloud on Nethermost Pike: summit wind broadly 10-30 mph, with gusts 35-45 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. 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. Any sunshine may be confined to lower ground or breaks away from the summit.

Drizzle is forecast for much of the day. The forecast total is around 5-10 mm, but local amounts will vary.

Cold on exposed tops: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind. Forecast models differ on summit wind strength: around 21-38 mph at walker height, with gusts 29-53 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. 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 surrounding model grid indicates 4.9 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.

The day on the hill

A wet day on Nethermost Pike: summit wind broadly 15-30 mph, with gusts 30-40 mph at times (a fresh breeze). Visibility may drop briefly in showers.

Patchy mist is possible in sheltered valleys early on.

Wind & exposure

Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Drizzle is forecast for much of the day, with some passing showers too.

The forecast total is around 2-5 mm, but local amounts will vary. Cold on exposed tops: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. 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.

Overall confidence is unavailable: insufficient comparable wind, rain guidance.

Cloud-free timing: Around 95% early, falling to around 45% later.

Full climbing & scrambling outlook

Conditions for exposed scrambling look mixed (42/100). 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 (Deepdale 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. Representative samples along available mapped routes also include Lapilli-tuff, Andesite and 3 other mapped types, 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 Nethermost Pike: summit wind broadly 15-30 mph, with gusts 30-40 mph at times (a fresh breeze).

Wind & exposure

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

Cloud & views

Cloud base around 1100–1400 m in the morning, then around 1300–1600 m around midday and 700–1000 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from early morning into the afternoon.

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

Sunny spells are possible away from summit cloud, but may not reach the top while it is in cloud. Drizzle is forecast for much of the day.

The forecast total is around 2-5 mm, but local amounts will vary. Cold on exposed tops: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind.

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

Full overnight outlook

Open-hillside camping looks mixed overall around 600 m (59/100). A lower pitch near 300 m looks more comfortable. Conditions are less suitable by 900 m. Open-ground gusts may reach about 35 mph. Seek meaningful shelter. Peak gusts range from about 25 mph at 300 m to 35 mph at 900 m. Around 2.4 mm is forecast, with rain liable to affect both pitching and packing up. Pitches near 900 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, 600 and 900 m. Ventilation will matter. The coldest temperature falls from about 7.3°C at 300 m to 5.1°C at 900 m.

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.
