The day on the hill

Little rain and limited summit cloud on Brown Clee Hill: summit wind broadly 5-15 mph, with gusts 10-20 mph at times (light winds).

Cloud & views

Cloud base mostly around 900–1200 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.

Rain & temperature

Little or no rain is forecast.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. 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 95% early, falling to around 85% later.

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 Microgabbro (Unnamed Igneous Intrusion Of Unknown Age). Generally grippy when dry and often still positive when damp, but wet slabs, lichen, polish and drainage lines can remain slippery. Representative samples along available mapped routes also include Sandstone and siltstone, interbedded, Mudstone, siltstone and sandstone and 2 other mapped types, so rock character and wet-weather behaviour may change across the mountain.

The day on the hill

On Brown Clee Hill: summit wind broadly 10-25 mph, with gusts 20-30 mph at times (a moderate breeze).

Things to watch

Thunder watch from early morning into around midday: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops.

If a thunderstorm develops, sudden gusts and heavy rain can change conditions quickly.

Cloud & views

Cloud base mostly around 1500–1800 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 northwestern slopes and lift somewhat on the southeastern side, but local terrain can differ.

Rain & temperature

Rain is likely to include a heavy spell, with around 2-5 mm expected over the assessed day.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. Some forecast models bring rain during the main walking period, while others keep it mostly dry.

Cloud-free timing: Around 85% early, improving to around 95% later.

The mapped summit rock is Microgabbro (Unnamed Igneous Intrusion Of Unknown Age). Generally grippy when dry and often still positive when damp, but wet slabs, lichen, polish and drainage lines can remain slippery. Representative samples along available mapped routes also include Sandstone and siltstone, interbedded, Mudstone, siltstone and sandstone and 2 other mapped types, so rock character and wet-weather behaviour may change across the mountain.

The day on the hill

On Brown Clee Hill: summit wind broadly 10-25 mph, with gusts 20-30 mph at times (a moderate breeze). Patchy mist is possible in sheltered valleys early on.

Cloud & views

Cloud base mostly around 1000–1300 m through daylight. The summit is likely to stay mostly clear.

Rain & temperature

Some rain is likely, totalling around 2-5 mm, but its timing and local amounts are uncertain.

Cloud height remains uncertain, especially where it is close to summit level. Forecast models disagree on cloud cover.

Cloud-free timing: Around 95% early, falling to around 75% later.

Full overnight outlook

Open-hillside camping looks reasonable overall around 600 m (70/100). It may be breezy on open ground, with gusts near 25 mph. Wind direction may change substantially during the night. Shelter that works at dusk may be less effective later. Around 3.1 mm is forecast, including rain around pitching time. Condensation risk is high near 300 m, so a wet pack-up is possible.

The day on the hill

A wet day on Brown Clee Hill: summit wind broadly 15-25 mph, with gusts 25-35 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 1000–1300 m in the morning, then around 500–800 m around midday and 1400–1700 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 around midday.

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

Cloud may hang lower on southern slopes and lift somewhat on the northern 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. The forecast total is around 2-5 mm, but local amounts will vary.

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.

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

Mapped variation

5 rock types appear across the available route samples

The summit type remains the forecast's cautious rock-response reference. Other mapped types show where conditions may behave differently elsewhere on the mountain.

Summit mapping Microgabbro Unnamed Igneous Intrusion Of Unknown Age Around 532 m Seen on Popular Brown Clee

Generally grippy when dry and often still positive when damp, but wet slabs, lichen, polish and drainage lines can remain slippery.

BGS record

Route sample Sandstone and siltstone, interbedded Senni Formation 365–446 m samples Seen on Popular Brown Clee

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.

BGS record

Route sample Mudstone, siltstone and sandstone Pennine Coal Measures Group Around 476 m Seen on Popular Brown Clee

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.

BGS record

Route sample Interbedded argillaceous rocks and [subequal/subordinate] sandstone Freshwater West Formation Around 306 m Seen on Popular Brown Clee

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.

BGS record

Route sample Limestone Upper Abdon Limestone Member Around 336 m Seen on Popular Brown Clee

Usually positive where it is rough and dry, but polished limestone can become very slippery when wet and seepage may linger.

BGS record

Generic exposed scrambling terrain; mapped summit-point bedrock is included where available, but route grade, exact rock, polish, drainage and escape options remain unresolved. Contains British Geological Survey materials © UKRI 2026. How to use the climbing and scrambling forecast.

Recommended kit for this dayWeather-aware packing prompts, plus your core hillwalking kitView kit

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.
