Why: Rain could reach the main walking period or hold off until later; forecast models disagree on the timing.
A risk of patchy rain or drizzle. Light northeasterly wind, with many tops staying clear.
High-ground wind (900 m)
Northeasterly around 10 mph at 900 m. Gusts reaching around 10 mph at 900 m, with locally higher values possible on the most exposed tops. Strongest early (around 10 mph), easing toward 5 mph later.
Walking impact
Little effect on walking, although exposed tops may still feel chilly.
Rain and showers
The odd passing shower, otherwise dry. Forecast models disagree on when the rain may arrive.
Cloud-free summits
Around 65%. Around 55% early, improving to around 75% later.
Cloud and visibility
Cloud bases mostly around 1200-1500 m. Bases should tend to lift as the day goes on. Cloud bases are likely to remain high, but some forecast models are much cloudier, so more extensive summit cloud remains a credible outcome. Many higher summits should stay clear, with useful views for much of the day.
Temperature and wind chill
Around 9°C at 900 m, feeling like 7°C in the wind.
Freezing level
Above the summits.
Daylight
Sunrise 06:15 — Sunset 20:24 — about 14.2 hours daylight.

Full regional climbing & scrambling outlook
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 psammite, pelite or semipelite, granite, gneiss or gabbro and volcanic rock; moisture response can therefore vary substantially between crags and routes.
