Seignosse - Les Bourdaines Surf Forecast and Surf Report

Alright, folks, Rusty here. Let's talk about what's on the table for this stretch of coast.

Right off the bat, we’ve got a bit of a waiting game. The first few days offer some small, clean windows, but nothing to get too fired up about. The real standouts are going to be a couple of mornings around the first week, and then another one further out.

Seignosse - Les Bourdaines, it’s a beach/jetty setup, expert territory when it gets going.

The action starts with a pulse on the morning of Tuesday, 1st September. We’ve got some clouds, a light offshore breeze from the ENE at 6 mph, and the swell’s wrapping in from the WNW at 5ft with a 10-second period. The ocean’s got some moderate energy on it (448), and the water’s sitting at a much warmer than average 74°. It’s a clean, proper start for those who can handle it, though the size is definitely one for experienced surfers only.

After that, the week quiets down. We have a few glassy mornings on Wednesday 2nd and Friday 4th, but the swell drops right off, barely reaching 3ft. It’s surfable, but ordinary. You’d be scratching around for anything fun.

Now, Sunday 6th September is another little highlight. The morning kicks off clear with a light cross-offshore breeze from the ESE at 9 mph. Swell’s holding at a clean 4ft from the NW, and the period stretches out to 11 seconds, giving the waves some proper shape and punch. The energy jumps up to a strong 311. Both the morning and the afternoon look clean, which is nice to see.

The following week has a couple of promising mornings. On Tuesday 8th, we get a glassy start with a light WSW breeze and a solid 4ft WNW swell (298 energy). That’s another good one for the morning session. The real standout, though, is Thursday 10th September. The morning is glassy calm with the swell pushing 5ft from the NW, a solid 10-second period, and energy ramping right up to 356. That’s the pick of the whole run—clean, meaty, and inviting for a good crew. But remember, at this size, it’s experts only.

Later on, Saturday 12th September morning also shows some promise, with a glassy SE breeze and 5ft NW swell (450 energy—strong stuff), so if you miss the 10th, that’s your backup.

After that, the second week fades, with most of the action getting messy with onshore winds or dropping in size. There’s a brief uptick on the 15th with a longer-period 12-second swell, but it’s battered by a strong onshore wind, so it’s not one to mark on the calendar.

So, for the straight goods: the best windows are Tuesday 1st September morning, Sunday 6th September, Tuesday 8th morning, and the standout Thursday 10th September morning. Make the most of those glassy, clean mornings.

Rusty.
