The Lowdown

Alright, folks, Rusty here. Let’s break down the next few weeks at Seignosse - Les Bourdaines. It’s a strange stretch, with a long stretch of small, messy surf, but if you’re willing to wait, we’ve got a couple of absolute crackers in the second week.

Right now, and for the next ten days, it’s a lot of work for not much reward. The beach is exposed, but the swell energy is just too weak. Most mornings we’re looking at tiny waves around 2 to 3 feet, with a bit of a north-west or west-north-west swell. The wind is often onshore or cross-onshore, so the surface is just choppy and ugly. The combined energy is barely over 100 for most of the first week, just a lot of weak, unexciting lines. You’ll get a few grovelly rides, but it’s hard work.

Things start to look a little more promising around the 21st of August. The swell ticks up a little, but the wind is still giving us trouble. By the morning of the 22nd, we’ve got a 3-foot swell from the north-west with a period of 10 seconds, and the energy finally climbs to 246. It’s still onshore wind, though, so it’s a marginal call. It’s a step in the right direction, but not the standout.

Now, here’s the one you’ve been waiting for. Sunday the 23rd of August is the undisputed best of the forecast. The morning is everything you want. The wind goes glassy, absolutely dead calm, from the north-north-east at just 5 km/h. The swell is a solid 7 feet from the north-west, with a period of 11 seconds. That’s proper groundswell, and the combined energy is a massive 1093. That’s serious power. This is an expert-only session, no question. At 7 feet, it’s too big for beginners, and the long period will make it heavy and powerful. For the experienced crew, it’s going to be a day of thick, clean bowls. The crowd situation here is “sometimes,” so you’ll want to get out early, but for that kind of quality, you won’t care.

The next day, Monday the 24th of August, is another interesting one, but with a different flavor. The morning is smaller, with a 3-foot swell from the west-north-west, but the period is a very long 15 seconds. That’s classic, clean groundswell. The wind is a light offshore from the east-north-east, so it will be clean. The energy is still strong at 606. This is a better option for the intermediate crowd, as the size is more manageable. Keep in mind, that super long period (15 seconds) means the sets will be very spaced out, but the waves will have a lot of push. On a beach break like this, it can sometimes make the waves a bit straight, but with the offshore wind, it’ll be worth a paddle.

Don’t get too excited about the end of the run. The 25th and 26th of August drop back into the small, weak, onshore zone. The main event is definitely that Sunday the 23rd. The water is about average for the time of year, so no crazy news there.

So, to sum it up: a lot of flat, frustrating days, but one absolutely firing Sunday morning on the 23rd for the experts, and a clean, long-period Monday on the 24th for the rest of us. Keep it on your radar.

Rusty.
