Forecast confidence: Forecast models differ on whether meaningful rain reaches the hills during the main walking period.

High spate risk

Burns and unbridged crossings may rise quickly. Assess them at the water and turn back if unsure.

Cloud-free timing: Around 25% early, improving to around 65% later.

A rough, clagged-in day on Whernside: summit wind broadly 25-40 mph, with gusts 40-50 mph around midday (gale-force winds). The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. High spate risk based on forecast rainfall. Burns and unbridged crossings may become difficult or impassable. Most likely from around 00:00 until around 14:00. Cloud base around 700–1000 m in the morning, then around 500–800 m around midday and 900–1200 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from late afternoon into the evening. Cloud height is close to summit level at times, so small local changes could put the top in or out of cloud. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. about 4 hours of sunshine is indicated, with cloud tending to break and brighter spells becoming more likely later. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (forecast models agree on the walking impact of the wind) - walker-height summit wind could reasonably be 29-36 mph, with gusts 41-50 mph. Cloud base is the least certain part of this - it could sit a couple of hundred metres either way, especially where it is close to summit level.

Full overnight outlook

Open-hillside camping looks mixed overall around 600 m (54/100). A lower pitch near 300 m looks more comfortable; conditions are less suitable by 600 m. Open-ground gusts may reach about 45 mph; seek meaningful shelter. Peak gusts increase from about 35 mph at 300 m to 45 mph at 600 m. A little rain or drizzle may coincide with pitching or packing up. From around 600 m upward, pitches may spend part of the night in cloud, with high condensation risk, persistent damp and poor visibility; 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 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.

The ground is likely to be very wet after recent rain; expect boggy approaches and choose a durable pitch carefully.

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 (0/100). Rain during the useful part of the day is likely to leave rock wet and more slippery. The mapped summit rock is Gritstone (Upper Howgate Edge Grit). 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 Interbedded limestone, argillaceous rocks and subordinate sandstone, Limestone and 1 other mapped type, 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. Cloud may also make route-finding and retreat harder.

Open-hillside camping looks reasonable overall around 600 m (61/100). Open-ground gusts may reach about 35 mph; seek meaningful shelter. Peak gusts increase from about 30 mph at 300 m to 35 mph at 600 m. Wind may shift from southwesterly to northwesterly; shelter that works at dusk may be less effective later. Around 4.8 mm is forecast, with a damp or wet pack-up most likely. From around 600 m upward, pitches may spend part of the night in cloud, with high condensation risk, persistent damp and poor visibility; 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 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 very poor (2/100). Rain during the useful part of the day is likely to leave rock wet and more slippery. The mapped summit rock is Gritstone (Upper Howgate Edge Grit). 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 Interbedded limestone, argillaceous rocks and subordinate sandstone, Limestone 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.

Forecast confidence: Cloud height is close to summit level at times, so small local changes could put the top in or out of cloud.

Cloud-free timing: Around 30% early, improving to around 70% later.

A mixed day on Whernside: summit wind broadly 10-20 mph, with gusts 20-30 mph during the afternoon (fresh and blowy). Cloud base around 400–700 m in the morning, lifting to 900–1200 m around midday and 1700–2000 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Cloud height is close to summit level at times, so small local changes could put the top in or out of cloud. Cloud is likely to hang lowest on northwestern slopes; the southeastern side should see somewhat higher bases and better breaks. about 10 hours of sunshine is indicated, with variable cloud giving brighter and duller spells. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. Cloud base is the least certain part of this - it could sit a couple of hundred metres either way, especially where it is close to summit level.

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.
