Porthleven is Cornwall's premier reef break, producing powerful, hollow waves that break over a rocky shelf in front of the harbour wall. Facing south-west, it needs a decent swell to work and is best at high tide. Not for beginners — strong currents, shallow reef, and heavy waves make this an experienced-surfer spot. When it's on, it's one of the best waves in the country.

AI Surf Overview

Conditions look mixed today with moderate onshore wind and a dropping swell period through the afternoon. Best bet is the early morning push before the wind picks up. Tomorrow looks cleaner with a slight shift in direction.
