Trestraou Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. The forecast for Trestraou is a bit of a mixed bag. We’ve got a decent pulse of swell coming through, but wind and conditions are going to be the real story. Let’s break it down.

The first surfable push arrives Sunday afternoon, August 30th. The ocean is kicking up a 5ft swell from the west, with a moderate 9-second period, bringing moderate wave energy (390). The water is a touch warmer than usual at 66°F, which is a nice bonus. However, the wind is a fresh 22 mph from the southwest, blowing cross-offshore. It’s clean, but that strong breeze is going to put a lot of texture on the face. The swell is a bit too big for beginners, and the conditions are poor, so it’s a "wait and see" session.

Monday, August 31st sees the swell really ramp up. Morning brings a solid 8ft west swell with a 10-second period, packing a punch of energy (1218). The wind is still a fresh 19 mph from the WNW, keeping it cross-off and clean. This is a big, powerful wave, well over 8ft, so it’s strictly for the experts. By afternoon, the swell drops a touch to 8ft, and the wind swings cross-shore, bringing in a bit of a cross-chop. It’s still a heavy lineup, but the quality is marginal.

Tuesday, September 1st offers a bit of relief. The morning sees a 4ft west swell, with a light 6 mph southwest wind making it cross-off and clean. Wave energy is moderate (282). It’s surfable, but very ordinary. The afternoon drops to 3ft and the wind goes cross-shore, making it poor.

From Wednesday, September 2nd through to Thursday, September 10th, it’s a long, dry spell. The swell drops to barely a ripple—between 1ft and 6ft—with poor conditions flagged for every single session. The wind is mostly strong and cross-off or cross-on, but the wave energy is weak (as low as 28). There’s simply nothing to get excited about. This is a gap of over a week with no real surf on offer.

Friday, September 4th offers a bit of a glimmer. The morning sees a 6ft swell from the WNW, with a longer 11-second period, giving it some proper groundswell power (866). The wind is 16 mph from the WSW, cross-off, and clean. The afternoon is bigger, at 7ft, with even more energy (1008). Both are rated as marginal, but it’s the best the forecast has to offer. The Trestraou setup is a sheltered beach break, and this swell direction (WNW) isn’t its optimum. With that long period, the waves might be a bit straight and fat, but for the experienced crew, there could be some clean, powerful walls.

Saturday, September 5th is a no-go. The swell is still there at 5ft, but the wind turns cross-on, making it choppy and messy. The same goes for the rest of the first week of September.

Friday, September 11th sees a small rebound. The morning has a 5ft west swell, with a clean cross-off wind. Wave energy is moderate (271). It’s consistent, but the conditions are still rated poor. By Saturday, September 12th, the swell drops to 3ft and the wind goes cross-on, so it’s not worth your time.

For the standout session, I’d have to point to Friday, September 4th. The morning offers a 6ft groundswell from the WNW, with a clean cross-off breeze. It’s the biggest, cleanest, and most powerful wave in the entire 16-day window. The energy is solid (866), and while it’s not the ideal direction for the break, the long period (11 seconds) means it’ll have some proper push. The conditions are marginal, but it’s the only real opportunity for a decent session. Build your plans around that.

Rusty.
