01

High-ground wind (600 m)

Southwesterly around 10 mph at 600 m. Gusts reaching around 15 mph at 600 m, with locally higher values possible on the most exposed tops. Temporarily strongest around midday, near 10 mph.

02

Walking impact

Little effect on walking, although exposed tops may still feel chilly.

03

Ground conditions

The ground is likely to be wet after recent rain.

04

Rain and showers

Across representative exposed-rock terrain

Full regional climbing & scrambling outlook

Conditions for exposed scrambling across the area look very poor (14/100). 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 sandstone or gritstone and granite, gneiss or gabbro; moisture response can therefore vary substantially between crags and routes.
