The Lowdown

Alright folks, Rusty here. Let’s get down to it. We’re looking at a slow start, but there’s a couple of bright spots if you’ve got the patience.

The forecast kicks off with a real flat spell. From Saturday the 15th through to the end of Monday the 24th, it’s grim. The surf is tiny, messy, and mostly blown out. There’s a solid 10-day gap where I wouldn’t even bother waxing the board. The swell energy is weak, usually under 100 (combined energy of all swells directed here), and the wind is mostly onshore or cross-onshore. You’ll see a few days with glassy mornings, like Tuesday the 18th and Sunday the 23rd, but the swell is so small—2ft to 2ft—it’s barely a ripple. Not worth the paddle.

Now, things start to look a little more interesting around Thursday the 20th. There’s a clean morning with a light cross-offshore breeze from the NE and a 3ft NW swell at 11 seconds. The combined energy jumps to 191 (moderate wave energy). This is at Seignosse - Le Penon (beach/jetty). It’s a beginner-friendly spot, but it’s inconsistent and can get crowded sometimes. The water temp is about average for this time of year, nothing weird going on.

The real standout, and the one to circle on your calendar, is the morning of Wednesday the 26th of August. The wind goes glassy, dead calm, out of the S. The swell is a clean 3ft from the WNW with a long 12-second period, and the combined energy is a solid 366 (strong wave energy). The forecast calls for “expect good surf conditions.” This is your window. The long period means better shaped waves, but at a beach/jetty setup, it might break a bit straight. Still, with glassy conditions and that energy, it’s the best we’ve seen.

But the absolute winner, if you’re an experienced surfer, is the morning of Thursday the 27th of August. We’ve got a 6ft WNW swell, a 10-second period, and a clean offshore breeze from the E. The combined energy is a thumping 511 (very strong wave energy). This is legit. The waves will have some punch. At 6ft, it’s getting a bit big for beginners, but for the rest of you, it’s prime. The offshore wind will keep it clean. The only downside is the afternoon goes cross-shore and a bit wonky, so get on it early.

After that, it fades back into mediocrity as we head into the end of the month. The 28th and 29th are back to small, onshore dribble. So, to sum it up: sit tight through the long flat spell, enjoy that glassy Wednesday the 26th morning for a fun session, and if you’re hungry for size, the offshore morning of the 27th is the real deal.

Rusty.
