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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look excellent (95/100). Rock is likely to be mostly dry, though seepage and shaded holds are not resolved. The mapped summit rock is Sandstone, siltstone and mudstone (Saltwick 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 Mudstone, so rock character and wet-weather behaviour may change across the mountain.

The day on the hill

A wet day on Roseberry Topping: summit wind broadly 10-25 mph, with gusts 25-35 mph at times (a fresh breeze). Visibility may drop briefly in showers.

Wind & exposure

Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops.

Cloud & views

Cloud base around 600–900 m through the morning, lifting to 800–1100 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. Very little direct sunshine is forecast.

Rain & temperature

Rain and drizzle are forecast for much of the day, with some passing showers too. The forecast total is around 10-20 mm, but local amounts will vary.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Forecast models differ on whether meaningful rain reaches the hills during the afternoon and evening.

Cloud-free timing: Best later at about 95%. Lowest around midday at about 85%.

Aurora may be visible after dark, with some favourable viewing conditions. Activity can change quickly. Check the After dark forecast below for viewing times and limitations.

Full climbing & scrambling outlook

Conditions for exposed scrambling look very poor (11/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Sandstone, siltstone and mudstone (Saltwick 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 Mudstone, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 30 mph.

Overnight · Aurora, stars & meteorsAfter darkBetaAurora possible View forecastClose forecast

After dark: aurora and stargazing

Night beginning 2026-09-23. All times are UK local time.

Aurora possible

Best forecast window: 24 Sep, 04:00 BST to 06:00 BST.

Look north-north-west, from the horizon part-way up the sky. A clear, open view that way matters more than height.

The Moon is below the horizon around the best forecast hour, so moonlight should not wash out a faint display then.

Aurora viewing guidance

Cloud is sampled overhead and towards the northern viewing horizon. Narrow cloud bands can still be missed. The available models broadly agree on cloud towards the viewing horizon.

The terrain horizon has not been checked at this exact location. Nearby slopes or a lower campsite can have a very different view.

More surrounding artificial light lies towards the aurora than at most assessed peaks. This may make a faint, low display harder to pick out.

Most likely a faint glow low in the sky that a phone camera shows better than your eyes. It can look like thin cloud.

Not sure what you are seeing? Take a Night-mode photo facing north: rest the phone on a rock or pack, use the main lens and a timer, and hold still for a 3–10 second exposure. Cameras show aurora colour long before eyes do.

Aurora activity can change quickly. This is experimental guidance, not a guaranteed sighting. Check again before heading out.

The day on the hill

Mostly dry with limited summit cloud on Roseberry Topping: summit wind broadly 5-15 mph, with gusts 10-20 mph at times (light winds).

Cloud & views

Cloud base around 1400–1700 m through the morning, lowering to 500–800 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 western slopes and lift somewhat on the eastern side, but local terrain can differ. Drizzle is forecast at times.

The forecast total is up to around 2 mm, but local amounts will vary. Cloud height and summit clearance are uncertain.

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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look poor (26/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Sandstone, siltstone and mudstone (Saltwick 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 Mudstone, so rock character and wet-weather behaviour may change across the mountain.

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.

Generic exposed-rock guidance

Full climbing & scrambling outlook

Conditions for exposed scrambling look very poor (4/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Sandstone, siltstone and mudstone (Saltwick 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 Mudstone, so rock character and wet-weather behaviour may change across the mountain. Gusts may reach about 45 mph. Crosswinds can make exposed ridges substantially more serious.
