Porthleven is Cornwall's heavy-water arena--a powerful reef break that detonates beside the harbour wall when sizeable SW groundswells wrap into Mount's Bay. The wave is an A-frame but the right is the prize.

Porthleven Reef is a reef break in South Cornwall, UK, with peaks that run both left and right.
Porthleven Reef picks up swell from the SSW round to the W, and it's best when it's coming straight out of the SW. It starts working at around 1.2m and handles up to about 3.6m, with the sweet spot around 2.3 to 3m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
A N wind is dead offshore at Porthleven Reef, and anything from the NW round to the ENE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
Porthleven Reef is at its best around the low to mid tide.
The most reliable run of swell at Porthleven Reef comes Oct to Mar. There's a second window in Apr and Sep too. Winter storms bring the best swells.
The water at Porthleven Reef averages around 12°C, so you'll want a 5/4mm with boots. It shifts a few degrees through the year, so check the season before you pack.
Not really. It's rated 8/10 for difficulty and suits experienced surfers. Expect a moderate crowd (5/10) when it's on. Extremely powerful wave breaking next to harbour wall. Shallow reef. Rocks everywhere. Very crowded when on.
The nearest airport on our list is NQY, then it's roughly a one-hour drive.
