The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. Looking at the charts for the next couple of weeks, it’s a bit of a flat spell on the horizon. There’s no real swell coming in, and what we’ve got is pretty weak. If you’ve got a kite, you might have more fun than on a surfboard for a lot of this.
The only window that even looks like it might offer a wave worth paddling for is early on, around Wednesday the 5th. We’re looking at a small, weak pulse of energy, with the combined swell energy only reading about 49. It’s a clean little cross-off breeze from the WNW at 6 mph, and the water is a mild 69°, which is pretty much normal for this time of year. It’ll be a dribbler, maybe 2ft, but with a short period of 7 seconds, it’s not going to have any punch.
After that, things just drop off. We get a few days with nothing but tiny, weak waves, plenty of days with no waves at all. There’s a bit of a bump on the morning of Friday the 7th, but at 2ft and with a period of 10 seconds, it’s not going to be worth the paddle out. The energy is still minimal, only reading 68. You’d be scratching for anything.
The rest of the period is a write-off, with mostly flat, weak conditions and energy readings in the single digits and teens. There’s a lot of days in a row where you simply won’t find a surfable wave. It’s one of those stretches where the beach is going to be more for sunbathing than surfing.
Honestly, don’t get your hopes up for any standouts over the next 16 days. The first week is a waiting game, and the second week looks just as quiet. It’s a typical summer flat spell for La Tranche sur Mer. If you’re not keen on a paddle with no waves, this might be the time to get the fishing rod out or just enjoy the beach. Forecasts can change, but right now, it’s all about patience.
Rusty, signing off.
