A grey, cloudy day on Ben Nevis: summit wind broadly 10-25 mph, with gusts 20-30 mph during the evening (fresh and blowy). The ground is likely to be wet after recent rain.

Cold on top: air temperature broadly 0 to 4°C, feeling around -6 to -2°C in the wind - wrap up. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 15-21 mph, so treat the headline as mid-range.
