The Lowdown

Alright, Rusty here. Let's talk about what's on the cards for Seignosse - Les Bourdaines.

Right now, the water's sitting at a balmy 72°, which is a touch warmer than it usually is this time of year—that's a nice little bonus. The first week is a mixed bag, nothing too special, but there are a couple of standouts that are worth waking up for.

For the upcoming Sunday the 13th, we've got some 5ft NW swell (wave energy is moderate at 531) but with a cross-shore wind, it's not going to be clean. Honestly, skip it. Monday the 14th morning looks better: glassy conditions, 4ft of NW swell at 11 seconds. That's a clean, fun-sized wave, but the energy is only moderate. A good morning session, not a headline act.

Things get interesting on Saturday the 19th. We're looking at a solid 7ft groundswell from the NW, with a period of 13 seconds. That's some proper energy—strong, with a combined reading of 1452. And the wind? Glassy in the morning. This is the highlight of the whole outlook. That size is firmly in the expert category, so it’s not for the faint-hearted, but for those who can handle it, it's going to be firing. The afternoon will see it drop a bit to 6ft and get bumpy with a cross-shore, so aim for that dawn patrol.

The spell continues into Monday the 21st. Another solid 6ft NW groundswell with 13-second period (energy at 1050), and clean offshore wind from the east in the morning. This is your second standout. Again, expert territory, but if conditions hold, it'll be worth the paddle.

After that, the surf tapers off. There's a lull from around Tuesday the 22nd through Thursday the 24th, where we see smaller waves (5ft to 2ft) and mostly onshore or cross-off winds. Not great. Friday the 25th and Saturday the 26th are tiny—1ft—and weak energy (under 100). Perfect for a learner, maybe, but otherwise not worth a mention.

Then, into the second week, there's a promising pulse brewing. Sunday the 27th morning kicks off with a 4ft long-period groundswell from the WNW at 15 seconds (moderate energy, 620) and clean offshore wind. Then Monday the 28th morning brings another clean 5ft NW swell with 13-second period (energy at 602). Both of those are worth a look, but being more than a week out, keep an eye on the forecasts—they could change.

So, to sum it up: your best bets are the mornings of Saturday the 19th and Monday the 21st. Big, clean, groundswell. The rest is a lot of small, choppy or onshore junk.

Rusty.
