> Windgather. Showers pass by quickly. You can see them coming. The car is only 2mins away if you need shelter. The crag has climbs in the lower grades that are not overly affected by being damp. Wind direction might even be favourable (face in the lee of the wind). Enjoyable small venue. Nik
Stanage has almost the same spec, but it's a billion times better.
But if the question were rephrased 'where is it less likely to rain', then I'd say Stoney Middleton is a good bet, but it's not Grit.
