The Lowdown
Alright, grab a seat. Rusty here, and I’ve gotta be straight with you—the next couple of weeks around Seignosse - Le Penon are looking like a bit of a slow burn. We’ve got a lot of small, messy days to wade through before we maybe see a glimmer of something rideable.
For the first week and a half, it’s a grim picture. From Wednesday the 12th right up through the 20th, we’re looking at non-stop poor surf conditions. Swell is tiny, mostly knee-to-waist high at best with energy readings down in the dumps (54 to 238 range). Winds are all over the shop, but mostly cross or cross-onshore, and that period is short—around 8 to 10 seconds—so the waves just don't have any punch. You’re better off saving your wax for later.
Now, the bright spot. If you’ve got patience, Friday the 21st of August is the one to circle. Early morning, we’ve got a glass-off and a clean, glassy ocean. The swell fills in to about 3 ft at a proper 9-second period from the NW, and combined wave energy jumps up to 260—that's moderate power, enough to make it fun. The water temp is sitting at 75°, which is a touch warmer than normal for this time of year, so the wetsuit might feel a bit less restrictive. Wind is dead calm. This is your window. After that, it deteriorates again into the afternoon as the wind swings cross-onshore.
After the 21st, we roll back into poor conditions. The 22nd and 23rd bring stronger onshore winds and messy surf. By the 25th, the swell actually picks up to 8 ft with a big energy reading of 638, but the wind is onshore and the comment says marginal. That size, at a beach break with onshore wind, would be a washing machine, not a wave. Too big for beginners (over 5 ft) and messy for everyone else. Late in the window, the 27th shows some cleaner conditions with a 5 ft NW swell and light winds, but they call it marginal.
So, bottom line: there’s only one standout in this whole 16-day stretch—the morning of Friday the 21st. Get out there if you can, because otherwise it’s a whole lot of waiting around.
Stay patient,
Rusty
