The day on the hill

On Thack Moor: summit wind broadly 15-30 mph, with gusts 35-45 mph at times (strong winds). Cloud-height uncertainty could put the summit in or out of cloud.

Clear spells may be difficult to time.

Cloud & views

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

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. Buffeting may affect balance on exposed ground, particularly near ridges and edges.

Cloud-height uncertainty could put the summit in or out of cloud, even where forecasts agree on the wider cloud cover.

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

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 good (77/100). Rock is likely to be mostly dry, though seepage and shaded holds are not resolved. The mapped summit rock is Sandstone (Stainmore 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. Gusts may reach about 35 mph. Crosswinds can make exposed ridges substantially more serious.

The day on the hill

On Thack Moor: 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. 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 models differ on summit wind strength: around 15-27 mph at walker height, with gusts 21-38 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. Cloud-height uncertainty could put the summit in or out of cloud, even where forecasts agree on the wider cloud cover.

Cloud-free timing: Around 75% early, falling to around 55% later.

The day on the hill

On Thack Moor: summit wind broadly 15-25 mph, with gusts 25-35 mph at times (a fresh breeze). Visibility may drop briefly in showers.

Cloud & views

Cloud base around 500–800 m in the morning, lifting to 800–1100 m around midday and 1000–1300 m by late afternoon. Summit cloud is extensive early, becoming less frequent later.

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.

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.

Forecast models differ on summit wind strength: around 17-25 mph at walker height, with gusts 24-35 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. Rain timing may shift by several hours, which could change how much of the main walking period stays dry.

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.

Full climbing & scrambling outlook

Conditions for exposed scrambling look fair (66/100). Recent rain may leave seepage and damp rock, especially on shaded sections. The mapped summit rock is Sandstone (Stainmore 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.

The day on the hill

On Thack Moor: summit wind broadly 10-25 mph, with gusts 25-35 mph at times (a fresh breeze).

Cloud & views

Cloud base around 600–900 m in the morning, then around 1100–1400 m around midday and 500–800 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from the 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 up to around 2 mm, but local amounts will vary. Forecast models differ on summit wind strength: around 15-26 mph at walker height, with gusts 21-36 mph.

Cloud height and summit clearance are uncertain. Check again nearer the time.

Exposed tops may feel chilly in the wind. A windproof layer will help, with an extra warm layer for stops.

Forecast confidence

Forecast models disagree on cloud cover.

Cloud-free timing: Around 75% early, falling to around 55% later.
