The Lowdown
Alright, let’s get into it. The next couple of weeks are looking like a bit of a mixed bag for us here at La Gravière. The forecast is a little messy early on, so don't get too excited for the first few days. We need to ride out some onshore winds and funky conditions before things start to clean up.
The water is running at 76.6°, which is much warmer than normal for this time of year – you can leave the boots at home.
The next week or so is pretty average. There’s some swell around, but it's coming in with cross/onshore winds and a lot of chop. Thursday, the 20th, is looking small and a bit stormy. Friday, the 21st, has a bit more size but it's poor with those cross-onshore winds and rain showers. Saturday morning, the 22nd, looks like the best of the early period – a clean 3.9ft from the northwest with a light offshore east wind, but it fades out in the afternoon. The waves are pretty weak and disorganized after that, with a few days of small, messy surf.
Hang in there, because the end of the month is where it gets interesting. On the morning of Sunday, the 30th, we’ve got a proper window. It’s glassy, with a 6.9ft west-northwest swell and nine-second period. The energy is moderate (749). This is La Gravière, (Hossegor - La Graviere) at its best – clean, pumping, and holding some size. That’s a standout session for sure.
Then, the following Wednesday morning, September 2nd, we’re looking another one. Another glassy morning with 6.6ft of west-northwest swell and a similar energy (646). Looks like another super clean, fun day.
That Thursday, September 3rd, also has some promise with a clean 5.6ft and an offshore-cross breeze. The first few days of September still have some decent energy before it starts to taper.
So, to sum it up: the first week is patience-testing, with Saturday the 22nd being the only real window. But the back half, especially the 30th and September 2nd, is looking solid. The long-range stuff is always a bit less certain, but those are the days I'd be circling on the calendar.
Alright, I’ll catch you all out there.
