The Lowdown

Alright folks, Rusty here. Let’s get straight into it. What a bleak stretch we’re looking at for Seignosse - Les Bourdaines. Honestly, for the next ten days or so, you can pretty much leave the boards in the car. The water is sitting at 75°F which is much warmer than usual for this time of year, but that’s about the only thing to get excited about.

From Wednesday the 29th of July right through to the morning of Thursday the 6th of August, it’s a flat spell. We’re talking tiny, weak swell energy—barely scraping 98 (combined energy) on the afternoon of the 29th, and then it just drops off into the doldrums. The wind is mostly cross-onshore or onshore, with a few glassy moments on the 5th of August morning, but there’s simply no swell to work with. It’s a write-off. The combined energy stays well under 100 for nearly two weeks, so you’re looking at a solid 10-day gap with nothing worth paddling out for.

Then, finally, on the morning of Friday the 7th of August, we get a flicker of hope. The swell bumps up to 4ft from the WNW, with a period of 8 seconds and combined energy hitting 239 (moderate wave energy). The wind is glassy, from the NNE at just 3 mph. That’s the standout window. It’s the only time in the whole 16-day forecast that the conditions line up for a proper session. Expect clean, glassy conditions, but remember, this is an expert-level break, and 4ft here on a beach/jetty setup will still pack a punch. The swell direction is from the WNW, and the optimum is from the W, so it’s not a perfect match, but with that glass, it’s the best we’ve got.

The Saturday the 8th of August morning is also worth a mention, with 4ft from the WNW and a light offshore wind from the east at 6 mph. The combined energy is 195 (moderate), and the conditions are clean. But it’s not as good as the Friday morning.

After that, it’s back to the grind. The mornings of the 9th, 10th, and 11th show some waist-high swell around 4ft to 2ft, but the wind is onshore or cross-onshore, and the wave comment reads “poor surf conditions.” By the 12th and 13th of August, we’re back down to depressing 1ft and 1ft mush. The swell period is short, the energy is weak, and the wind is onshore. It’s a real bummer for this region.

So, to sum it up: if you’re a local, mark your calendar for the morning of Friday the 7th of August. That’s your one true shot. Otherwise, it’s a long, flat wait. For the rest of the 16 days, you’re better off finding a different hobby.

Stay frothy,
Rusty
