The Lowdown
Alright folks, Rusty here. Gotta be straight with you – looking at the next 16 days for the Seignosse - Les Bourdaines area, it's a real mixed bag. We've got a long stretch of small, average conditions before a couple of windows that might just make it worth hanging on.
The water is much warmer than normal for this time of year, sitting at 75°F at the start, which is a nice touch for the early morning sessions.
First up, we get a little taste on Thursday morning, the 6th of August. It's cloudy, with a light NNE cross-offshore breeze and a small 3ft NW swell. The energy is weak (121), but it's clean. Honestly, it's surfable but very ordinary. Not a standout.
Then we hit a dry spell. From Thursday afternoon right through to the morning of Sunday the 9th, it's mostly poor conditions with tiny, weak waves. Friday morning the 7th has a 2ft onshore W swell with clean wind, but the period is a short 7 seconds and the energy is low. It's a no-go.
Sunday morning the 9th offers a glimmer. Glassy, calm conditions with a 2ft NW groundswell. The period jumps to 10 seconds, which is decent, but the energy is still weak (78). It's surfable, but you're not going to write home about it. This pattern of small, glassy mornings with very ordinary 2ft waves and weak energy continues through Monday the 10th, Tuesday the 11th, and into the following week.
The real action doesn't look like it's coming until the 18th of August. Monday afternoon the 17th sees a bump in swell to 4ft from the NW, but the cross-onshore wind makes it choppy and messy.
But listen, Tuesday the 18th is the first real standout. The morning of the 18th is glassy with a 4ft NW swell. The combined energy jumps to moderate (138). That's a proper session for the experienced surfer. The afternoon gets a bit bigger at 4ft and the energy spikes to 332, but the cross-onshore wind will chop it up. For the experts, that morning glass is the pick of the first week.
The best stuff, though, is a long-range promise. Keep your eyes on Thursday the 20th and Friday the 21st of August. Thursday morning has a clean offshore breeze from the E, with a 2ft NW swell. But the key is the period: it's a very long 12 seconds. That's real groundswell energy (121). Friday morning the 21st is even better. Clean offshore E wind again, with a 4ft NW swell, a 9-second period, and strong energy (190). This is the best-looking setup on the whole forecast. It's a proper point-break-feeling swell with light winds, so it should be clean and lined up. Just remember, this is over a week out, so it's a promising call, not a guarantee.
The rest of the time is filled with small, onshore or cross-shore slop. For the non-expert, those bigger days on the 18th and 19th are over 5ft, so they might be a handful. The best bet for everyone is to pencil in the 20th and 21st mornings.
Rusty out.
