The Lowdown
Right then, let's get into it. The next couple of weeks are looking pretty flat for the most part, but there's a glimmer of hope if you're patient.
Straight up, we've got a massive gap here with no real surf to speak of. From now through to the end of July, it's all tiny dribble and poor conditions. Don't even bother getting your hopes up. You're looking at a solid week of flatness before anything worth paddling out for shows up.
Finally, on the morning of the 1st of August, there's a faint pulse. The early session at La Tranche sur Mer will see a tiny 1 ft W swell with a very long period of 12 seconds. The wind is clean and cross-off, and it's only a gentle breeze, so it'll be tidy. The wave energy is weak though, only 77. It's surfable but very ordinary. You wouldn't kick it out of bed, but it's barely a wave.
Things get a bit more interesting on the afternoon of the 1st of August. The same W swell jumps to 3 ft, with an 11 second period and moderate energy reading of 372. Still cross-off winds but a moderate breeze now. The swell direction from the west is spot on for what this beach/jetty setup likes. It's still on the small side for a proper session, but it's the best on the whole 16-day run. For the absolute patient surfer, that's your window.
After that, we're back into the small stuff. Through the first week of August, you'll see a few 2 ft to 3 ft W swells with clean, cross-off winds or, on the morning of the 4th, even glassy conditions. But the energy remains weak (76-99) and the conditions are still described as "surfable but very ordinary." It won't stop you from getting wet, but there's no power or push.
Given the long flat run and the small, weak swells that follow, and with it being a beach/jetty setup, the kite surfers might actually have more fun these two weeks than us paddle surfers.
