Best Time for Dorset & the Jurassic Coast: Bournemouth to Lyme Regis

Last updated: 2026-09-23

Preferred months for this journey: May, June, July, August, September. Check the seasonal notes before choosing your dates.

Sea warm enough to swim at Durdle Door by late June, fossil-hunting tides at their most generous, and the coast path dry underfoot.
Winter storms are exactly when fresh fossils wash out of the Lyme Regis cliffs — bring waterproofs and watch for rockfalls after rain.
