Sweet spot: March, April, May. Computed from NASA POWER climate normals across the route's overnight towns, balancing temperature, rainfall and daylight.
💡 Good to know

- Winter storms are exactly when fresh fossils wash out of the Lyme Regis cliffs — bring waterproofs and watch for rockfalls after rain.
