Hossegor - La Graviere Surf Forecast and Surf Report

Alright, Rusty here. Grab a coffee and let’s talk about the next couple weeks at Hossegor – La Graviere. The water’s sitting at a nice 72°F, which is a touch warmer than normal for this time of year, so that’s a bonus.

We start off with a bit of a letdown this Saturday morning, September 12th. There’s swell, but it’s pretty weak at 3ft from the WNW with a short period of 8 seconds. The combined energy is low (90). On the plus side, it’s absolutely glassy, so if you’re desperate for a paddle and have a longboard, you could get a few grovelly ones. The afternoon turns to junk with a cross-shore wind.

The real action kicks off on Sunday the 13th. This is where it gets interesting. That morning, we see a jump to 4ft from the NW, but the period stretches to 13 seconds and the energy surges to 501. It’s clean as a whistle with glassy conditions. That’s a good-looking groundswell. Then Monday morning the 14th keeps the fun going with 4ft, a 10-second period, and clean conditions. The energy is still moderate (389). These two mornings are your standout sessions for the first week – clean, punchy, and fun.

There’s a bit of a lull mid-week with onshore junk until we get to Thursday the 17th. Thursday morning is a beauty. We’ve got 5ft from the NW, an 11-second period, a big jump in energy to 650, and dead glass. That wave comment says “very good,” and I’m not arguing. This is a solid swell, but at that size, the sandbars at La Graviere will be pitching. It's still fine for strong intermediates, but beginners might find it a bit of a handful.

Now, the crown jewel of this entire outlook lands on Saturday the 19th. Saturday morning has 6ft of NW swell with a 13-second period and a massive energy reading of 1018. That’s proper power. The wind is glassy, the direction is perfect for the sandbank. This is an excellent setup for experienced surfers. If you can only surf one day, make it this one. The afternoon gets choppy again, so get your fill in the morning.

Sunday the 20th and Monday the 21st mornings keep the quality high with offshore winds and 4ft to 5ft of clean NW swell. Solid, consistent waves with good energy.

The run continues into the second week, but it starts to taper. Tuesday the 22nd morning is still clean with 5ft and moderate energy (515). From Wednesday the 23rd onwards, it fades. The energy drops, the swell gets smaller, and the winds turn more cross or onshore.

By the weekend of the 26th and 27th, the size is down to 1ft to 3ft, but the period gets long again (14-15 seconds). That long period, small groundswell is often a bit too straight for the beach break, but with cross-offshore winds on the 27th, you might find a clean little corner if you know where to look. The energy is still there (384), but it’s a shadow of the week before.

So, to keep it simple: Sunday the 13th morning and Saturday the 19th morning are your best bets. The 19th is the real standout for power. Get out there.

Rusty.
