The day on the hill

On Black Fell: summit wind broadly 15-35 mph, with gusts 35-45 mph at times (strong winds).

Cloud & views

Cloud base around 800–1100 m through the morning, lifting to 1100–1400 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.

Rain & temperature

The ground is likely to be wet after recent rain. Little or no rain is forecast.

Forecast models differ on summit wind strength: around 24-30 mph at walker height, with gusts 33-42 mph. 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.

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). Recent rain may leave seepage and damp rock, especially on shaded sections. 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 Andesitic tuff, 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 Black Fell: summit wind broadly 10-20 mph, with gusts 20-30 mph at times (a moderate 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 for much of the day. The forecast total is around 2-5 mm, but local amounts will vary.

Forecast models differ on summit wind strength: around 14-25 mph at walker height, with gusts 20-35 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Summit wind could be roughly 14-25 mph, which changes how difficult exposed walking may feel.

The day on the hill

Little rain and limited summit cloud on Black Fell: summit wind broadly 10-20 mph, with gusts 20-30 mph at times (a moderate breeze).

Cloud & views

Cloud base around 1700–2000 m around midday, lowering to 1300–1600 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. Exposed tops may feel chilly in the wind.

A windproof layer will help, with an extra warm layer for stops.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look fair (73/100). Recent rain may leave seepage and damp rock, especially on shaded sections. 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 Andesitic tuff, so rock character and wet-weather behaviour may change across the mountain.

The day on the hill

A wet day on Black Fell: summit wind broadly 5-20 mph, with gusts 15-25 mph at times (a moderate breeze). Patchy mist is possible in sheltered valleys early on.

Cloud & views

Cloud base 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 southwestern slopes and lift somewhat on the northeastern side, but local terrain can differ. Very little direct sunshine is forecast.

Drizzle is forecast for much of the day. The forecast total is around 2-5 mm, but local amounts will vary.

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