The Lowdown
Alright, Rusty here, and we’re looking at the next couple of weeks at Hossegor’s main sandbar, La Graviere. The overall pattern is a slow start followed by a solid pulse of quality groundswell, but you’ll need to pick your windows carefully because the wind is going to be a bit of a headache at times.
Things kick off real slow. This Sunday afternoon (the 13th), there’s a little 5ft NW swell coming in, but a northerly cross-breeze is chunking it up, and the water is a touch warmer than usual for this time of year at 72°. Honestly, it’s not worth getting wet for. You’ve got a couple of days of nothing special after that. Monday morning (14th) is a tease – 4ft of NW swell, glassy conditions with an easterly offshore. That’s a clean session, but it's small. The swell energy is moderate (389). For a spot like this, you want more push. The rest of the week is pretty ordinary; Tuesday (15th) is a write-off with onshore winds and tiny, weak surf.
We get a few more pulses mid-week, but the wind stays messy. Wednesday afternoon (16th) sees the swell bump up to 5ft, but it’s on the cross-on breeze and choppy. The wave energy is still moderate (441), but it’s just not clean. Thursday and Friday stay in that same frustrating loop – some size (5-6ft) but the cross-onshore wind kills it. The energy is moderate to moderate-strong (677 and 604). It’s more of a kite-surfing setup than a paddle one right now.
Now the standout window we’re waiting for.
The real action fires up on Saturday morning the 19th. That’s the one. We’ve got a solid 7ft NW groundswell rolling in with a long, powerful 13-second period. The combined energy is strong (1452). On top of that, a glassy, offshore easterly breeze. That is the recipe for a proper session at Graviere, but fair warning: at this size, this is for experienced surfers only – it’s gonna be hollow. The wind stays clean offshore throughout the morning.
The action continues into Monday morning the 21st. Another excellent window. You’ve got 6ft of NW swell with a clean, 10 mph offshore easterly. That’s 13-second groundswell again, delivering good shape. The wave energy is strong (1050). This is your second standout session of the run.
After that, we drop off. The wind turns cross-onshore and the swell backs down into the middle of the week, leaving just average, choppy conditions. The forecast for the 23rd and 24th is pretty flat and messy.
Look out to Sunday the 27th and Monday the 28th – the long-range charts are showing a promising window. We could see a nice 4ft to 5ft WNW swell with a very long 15-second period and a clean, light offshore easterly wind. The energy is moderate-strong (620 and 602). That’s a longer period, which means longer waits between sets but better shaped waves on a sandbar like Graviere. It’s still a bit of a wait, so not locked in, but it’s a solid possibility.
Bottom line: Saturday the 19th morning is the top pick – big, clean, heavy. Monday the 21st morning is a close second. The early weeks are for the locals who don’t mind small, clean waves, and the very end of the window has potential.
Rusty.
