Why: Thunderstorm timing is inherently uncertain and may shift by several hours.
Thunderstorms are the main concern, especially on exposed summits and ridges. A noticeable southwesterly breeze and Showers or rain at times.
High-ground wind (500 m)
Southwesterly around 15 mph at 500 m. Gusts reaching around 20 mph at 500 m, with locally higher values possible on the most exposed tops. Temporarily strongest around midday, near 15 mph.
Walking impact
Noticeable on exposed ground, but unlikely to impede most walking.
Thunderstorms
A moderate thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed summits or ridges while storms are building or nearby.
Ground conditions
The ground is likely to be wet after recent rain.
Rain and showers
Showers or spells of rain at times. The heaviest rain is expected around the middle of the day.
Cloud-free summits
Around 55%. Around 60% early, falling to around 50% later.
Cloud and visibility
Cloud bases mostly around 600-1100 m. Bases are likely to lower later in the day. Cloud bases are likely to remain high, but some forecast models are much cloudier, so more extensive summit cloud remains a credible outcome. Cloud is likely to come and go on the higher summits; breaks may be useful but not dependable.
Temperature and wind chill
Around 11°C at 500 m, feeling like 9°C in the wind.
Freezing level
Above the summits.
Daylight
Sunrise 06:29 — Sunset 20:01 — about 13.6 hours daylight.

Full regional overnight outlook
Across representative hills, open-hillside camping looks mixed around 300 m (55/100). Little rain is expected, but cloud or condensation could still mean a wet pack-up.

Full regional climbing & scrambling outlook
Conditions for exposed scrambling across the area look poor (38/100). 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; moisture response can therefore vary substantially between crags and routes.
Representative summit-point samples across the region; individual crags and routes may differ.
