Hossegor - La Graviere Surf Forecast and Surf Report

Alright, let’s talk about what’s happening at Hossegor - La Graviere. This is a world-class sandbar, set up for advanced surfers, and it’s consistently exposed to westerly swell. The water temperature is sitting at 75°, which is 5° above normal for this time of year – that’s way warmer than usual, so you can leave the thick rubber at home.

The next few days are pretty grim. Thursday morning the 27th is a write-off: tiny 1ft swell from the northwest with only 8 seconds of period, and glassy conditions can’t save it. Energy is just 23. That’s next to nothing. Thursday afternoon is also flat with weak cross-onshore wind. Friday the 28th morning brings a bit more size at 2ft, but it’s onshore and messy. By Friday afternoon, we get a 4ft swell from the west-northwest, but the period drops to 7 seconds, so it’s fat and weak with moderate energy (222). The score is poor.

Saturday morning the 29th is the first real glimmer. Swell jumps to 5ft from the west-northwest with a 9-second period, and it’s glassy. Energy is 424. That’s moderate energy and the surf should be clean. But then Saturday afternoon gets cross-shore and choppy. Sunday the 30th morning is clean again: 4ft, west-northwest, with offshore east-southeast wind at 3 mph. Energy 357. Solid options if you get out early.

Sunday afternoon goes cross-onshore and choppy with 6ft and 10-second period – energy jumps to 511, but the wind ruins it. Monday the 31st is a mixed bag of cross-onshore winds and marginal conditions. Tuesday the 1st of September morning brings a 5ft west-northwest swell with clean cross-offshore wind from the east-northeast. Energy 411. That’s a good window.

Wednesday the 2nd and Thursday the 3rd are small and ordinary. Then Friday the 4th morning is flat with 3ft and glassy conditions – energy only 112. Not worth paddling out.

Now, here’s where it gets interesting. Saturday the 5th of September morning is a standout. Swell 5ft from the northwest with a long 12-second period. Energy hits 590. Winds are light offshore from the east-southeast. This will be clean, well-shaped surf. The longer period means more energy and better shape, but it can make waves break a bit straighter on a beach break – still, La Graviere is a sandbar and handles it well. This is the best session of the forecast.

Sunday the 6th of September morning is also excellent: 5ft northwest swell, 11-second period, glassy with zero wind, energy 505. That’s a classic morning session. The afternoon gets cross-shore and choppy.

Monday the 7th is onshore and poor. Tuesday the 8th of September morning is another strong one: 5ft northwest swell, 11-second period, energy 629, with clean offshore wind from the east-southeast. That’s a very good window. The afternoon goes cross-shore and messy.

Wednesday the 9th and Thursday the 10th see a bigger pulse – 8ft on Wednesday afternoon from the west-northwest, period 9 seconds, energy 809. That’s strong energy, but it’s cross-onshore and choppy. Thursday the 10th morning is 7ft northwest, period 9 seconds, energy 770, with light cross-shore wind. That’s big for this spot – over 8ft, it’s expert territory. The wind isn’t perfect, but the swell is there.

Friday the 11th of September morning is a clean finish: 4ft from the west-northwest, 10-second period, offshore wind from the east, energy 270. Clean and fun.

So the standout windows are Saturday the 5th and Tuesday the 8th of September mornings. Those are the ones to circle. The long-period groundswell on Saturday will give you power and shape, and the offshore wind will keep it clean. Get on it.
