The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Hossegor's famous sandbar, La Graviere, over the next couple of weeks.
We’re starting off a bit flat and frustrated. Monday the 7th and Tuesday the 8th are pretty much a write-off with messy onshore winds and small, weak swell. You’re better off waiting it out. The water temp is sitting at a warm 73°, which is a touch warmer than normal for this time of year, so at least you won't be freezing while you’re sitting there waiting for nothing.
Things start to perk up a little on Wednesday the 9th morning. We get a clean cross-offshore breeze from the North with a 6ft NW swell, but the period is a short 9 seconds, so it's gonna be a bit lumpy and disorganised. The combined energy is moderate (550), but it’s more of a powerful chop than a proper clean wave. The afternoon gets blown out again.
Now, Thursday the 10th morning is where I’d be looking. It's a standout. The wind goes glassy out of the ENE, and we've got a clean 4ft NW groundswell with a 10-second period. The combined energy is moderate (312), but with those glassy conditions, La Graviere will be offering up some proper A-frame peaks. This is the best on offer for the first week. The crowds at Hossegor are always a factor, so expect it to be busy, but the quality will make it worth the paddle battle.
Friday through to Tuesday the 15th is a real mixed bag. We see some glassy mornings with tiny waves around 2ft, and then the afternoons get choppy. It’s a wait-and-see game, nothing to get too excited about.
Sunday the 13th morning is another one to circle. The swell jumps to a solid 5ft from the NW with a very long 13-second period, combined energy reading a strong 703. With a glassy WSW breeze, this is prime La Graviere. That long period means the waves will have serious push and shape, though at a beach break like this, the long-period swell can sometimes straighten out a bit. Still, the potential is huge.
We get another taste of that on Monday the 14th morning, with a clean 4ft NW groundswell, 12-second period, and glassy conditions. Not quite the power of Sunday, but still a very good session.
The second week starts to heat up again. Wednesday the 16th morning has a clean 4ft WNW swell, and then Thursday the 17th morning looks like a real cracker. A 5ft NW swell with an 11-second period, clean offshore winds from the East, and a combined energy of 518 (strong). That’s expert territory at that size, and with that power, it’s going to be a heavy, barreling day. Only for the experienced crew.
The weekend of the 19th and 20th looks promising too. Saturday the 19th morning has a 5ft NW groundswell with a very long 13-second period, offshore ESE winds, and a combined energy of 837 (very strong). That’s a lot of water moving. It’s a serious, powerful swell, so again, this is strictly for experts who know the bank. The morning window is the one to score.
Into the final few days, we see a few more clean, glassy mornings with 4ft to 4ft swells, but the real standout power has faded.
Overall, the best windows are the Thursday 10th morning for a fun, clean session in the chest-high range, and the Sunday 13th morning and Thursday 17th morning for bigger, more powerful, expert-level waves. If you can only pick one, Sunday the 13th morning with that glass and long-period groundswell is the one to aim for.
Rusty.
