The Lowdown

Alright, let’s break down the next 16 days for our local spot. The first real surf arrives on Saturday the 5th, so Thursday and Friday are a wash. The pattern is a bit up and down – some clean windows, but plenty of onshore junk in between. The best windows are Sunday the 13th morning with a clean offshore wind, and Wednesday the 16th morning with glassy conditions and a solid swell.

Seignosse - Les Bourdaines is the only break in the mix. It’s a beach and jetty setup, exposed to the west, and it’s consistent, so there’s usually waves. The water is running at 74°, which is 4° above the long-term average – that’s much warmer than usual for this time of year, so you might be able to get away with a shorty or even just boardies.

Saturday the 5th morning is the first real chance. Light easterly offshore wind, 3ft of swell from the WNW with a 9-second period, and the combined energy is moderate at 233. It’s clean, but nothing special. The afternoon jumps to 5ft from the NW with a 13-second period (groundswell) and energy at 734 – that’s strong. But the wind goes north and cross-shore, making it a mess. That long period at a beach break can make it a bit walled, but for experts, the power is there.

Sunday the 6th morning has 5ft of NW swell (12 seconds, 551 energy) but light cross-onshore wind from the NW, so it’s bumpy. Not great.

Monday the 7th and Tuesday the 8th are mostly poor with onshore winds and small, weak swell. Wednesday the 9th morning gives a little window: 4ft NW swell, 9 seconds, light easterly offshore, and clean. Energy is only 188 though, so it’s small.

The standout is Sunday the 13th morning. We’ve got 5ft of NW swell with an 11-second period, 471 energy, and a clean offshore breeze from the ENE at 15 km/h (9 mph). That’s proper clean conditions with a decent push. The swell direction is WNW, and the optimum for this spot is west, so it’s a good match. The water is still warm, and the offshore wind will keep the faces smooth. This is the best window.

Then Wednesday the 16th morning is a gem. Glassy, dead calm, with 5ft of NW swell at a 10-second period and energy at 508. That’s strong, clean swell with no wind. The size is over 5ft, so it’s a bit much for beginners, but for anyone with experience, it’s going to be a treat. The morning glass will make it buttery.

Thursday the 17th morning is also worth a look: 4ft from the WNW, 10 seconds, glassy, 260 energy. Clean and small.

After that, Friday the 18th and Saturday the 19th drop off with poor conditions and small swell. So the call is: Sunday the 13th morning for the best combo of clean offshore wind and decent swell, and Wednesday the 16th morning for the glassy, slightly bigger conditions. The rest is a mixed bag.
