The Lowdown
G'day, Rusty here. Look, I'm gonna level with you – the next 16 days are a tough watch for this stretch of coast. We're looking at a whole lot of nothing for the first week and a half, with only a brief, half-decent window right at the very end of the forecast period. It's a pretty barren run for L'Arène (Cassis - Plage de l'Arène).
Things are flat and messy to start. Between the 30th of August and the 10th of September, the swell is tiny – we're talking nothing over 2ft – and the wind is mostly cross or cross-onshore, keeping things choppy and ugly. The combined wave energy is, frankly, pathetic, barely cracking double digits. There are a few mornings with clean conditions, like the 3rd and 4th of September, but there's just no wave to surf. You're not missing a thing.
Right, so the only glimmer of hope shows up on the 5th of September (Saturday). The swell finally kicks up to a solid 6ft from the WNW, with a period of 6 seconds, and the combined energy jumps to a moderate 163. It's still not ideal, with a moderate cross-shore wind putting a bit of a chop on it. By the afternoon, the swell pushes to 6ft and the energy to 263, but the wind picks up to a fresh 22 mph cross-shore, creating a lumpy mess. Honestly, with that much wind and those conditions, it looks more interesting for kite surfing than a clean paddle session.
We then get a complete shut-down from the 6th through the 10th with nothing but flat, glassy mornings and tiny, wind-affected afternoons.
The only real standout comes much later. Mark your calendars for the 11th of September (Friday). The morning serves up a clean, glassy session with a 5ft NW groundswell pushing through. The period is a solid 6 seconds, giving it a bit of push, and the combined energy is a healthy 120. With the wind dead calm and glassy conditions, it'll be your best chance for a clean wave, even if the swell is on the smaller side for that energy level. For you beginners, 5ft might be a bit much, but for everyone else, that early session is your target.
Overall, it's a grim fortnight. The 11th morning is the one to aim for.
Rusty.
