Lewis and Harris
A fine day in Lewis and Harris: light winds and clear tops for most of the day, though expect spells of drizzle.
Sunshine and sky
Cloud breaking up. Brighter spells should become more frequent as cloud breaks.
These are direct modelled sunshine hours during daylight, not the probability of sunshine. Cloud cover and summit cloud are assessed separately in the forecast above. The regional median prevents one unusually bright or dull summit cell defining the whole area.
Overnight forecast: 17:00–08:00 (UK local time), in Wild camping below.
High-ground wind (700 m)
At around 700 m, expect a north-westerly wind of 10–20 mph, gusting 15–25 mph.
Walking impact
Noticeable on exposed ground, but unlikely to impede most walking.
Ground conditions
The ground is likely to be wet after recent rain.
Rain and showers
Spells of drizzle, mostly in the early afternoon. Expect 2–5 mm in total.

Clear-summit estimate: about 90% early, about 90% around midday and about 90% later.
Cloud and visibility
The tops should stay clear of cloud all day.
Temperature and wind chill
At around 700 m it will be 2 to 6°C, feeling like -2 to 2°C in the wind. Take a hat, gloves, a windproof and a spare warm layer. Pack waterproofs too, and keep a warm layer dry in your pack.

Regional climbing & scrambling outlook
A broad guide to dampness and exposed rock across the area, not a forecast for every crag. Lower, sheltered crags and individual rock types may behave differently.
Conditions for exposed scrambling across the area look mixed (55/100). Rain is likely to leave rock wet. Polished slabs, vegetation and drainage lines may be notably worse. Mapped summit-point geology across the representative hills includes granite, gneiss or gabbro. Rock can therefore respond differently to moisture between crags and routes.
Representative summit-point samples across the region; individual crags and routes may differ.
Generic exposed hands-on-rock terrain across representative summits; mapped summit-point geology is a broad regional sample, not a named-route survey. 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.
