Conditions for exposed scrambling look mixed (53/100). Rain during the climbing period is likely to leave rock wet and more slippery. The mapped summit rock is Mudstone (Portfield Formation And Haverford Mudstone Formation (Undifferentiated)). Often positive when dry, but smooth, polished or slabby sections can become markedly more slippery when damp.

The day on the hill

Light rain for several hours on Broadway Hill: summit wind broadly 10-25 mph, with gusts 25-35 mph at times (a fresh breeze).

Things to watch

Thunderstorms are possible from the morning into the evening. Keep an escape route from exposed ridges and descend if thunder develops.

If a thunderstorm develops, sudden gusts and heavy rain can change conditions quickly. Patchy mist is possible in sheltered valleys early on.

Cloud & views

Cloud base around 600–900 m in the morning, then around 800–1100 m around midday and 500–800 m by late afternoon. The summit is likely to stay mostly clear.

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 16-30 mph at walker height, with gusts 22-43 mph.

Forecast confidence

Cloud height remains uncertain, especially where it is close to summit level. A low thunderstorm risk remains difficult to time precisely.

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.
