For crags with mixed wall types, CodClimb scores Exposed (slab, face) and Overhang (cave, roof) separately — overhangs ignore rain and win on wet days.

Sun & shade timeline

Drag an hour-by-hour timeline to see when a wall is in sun or shade today — computed from the crag's aspect and the sun's path. Plan the cool window or chase the sun.
