Capbreton - La Piste Surf Forecast and Surf Report

G’day, Rusty here. This outlook for La Piste is a bit of a mixed bag—long stretches of waiting punctuated by a couple of clear windows that’ll be worth the patience. We’ve got a solid run of days with poor conditions up front, but the second half of the window shapes up nicely if you play it right.

First off, the water temp is about average for this time of year, so no surprises there. The early days from Tuesday the 25th through Thursday the 28th are all poor—tiny, weak swell with short periods (4 to 8 seconds) and a combined energy that’s barely reaching 157 (moderate at best, but mostly weak). Winds are onshore or cross-onshore, and the surf is small and messy. Not worth paddling out.

Friday the 28th sees a jump in size—6ft to 8ft from the WNW with period around 8-10 seconds—but it’s still tagged as poor. The combined energy hits 468 then 1405 (moderate to strong), but winds are onshore and the conditions are rough. For advanced crew only if you’re keen on a messy, powerful session, but I’d hold off.

Now for the good stuff: Saturday the 29th morning is a proper standout. Glassy conditions, light ESE offshore wind, and a clean 5ft swell from the WNW at 9 seconds. The combined energy sits at 362 (moderate), and the forecast says good surf. This is your best early window—clean lines, manageable size, and the offshore breeze will groom it nicely. Crowds are often a thing at La Piste, so expect company.

Sunday the 30th morning is another glassy one: 5ft from the WNW at 8 seconds, combined energy 339 (moderate), and clean glass. Again, good surf. But the afternoons both days get chopped up by cross-shore winds, so mornings are the go.

There’s a dry spell through Monday the 31st and Tuesday the 1st of September—poor conditions, cross-onshore, moderate energy in the 151-522 range but no quality. Wednesday the 2nd morning offers a brief clean window with glassy conditions and 3ft at 9 seconds (energy 151, weak), but it’s very ordinary surf.

Then we get a real standout: Sunday the 6th of September. Both morning and afternoon are clean, with cross-offshore winds from the SSE and NE, and 6ft swell from the WNW at a nice 11-second period. Combined energy is 876 (strong). This is groundswell, and while La Piste is a fairly exposed beach break, the longer period will give it more shape and power. Crowds are often here, but if you get it on this Sunday, it’ll be quality. This is the best call of the whole 16-day window.

A quick heads-up: Tuesday the 8th of September sees a massive 12ft to 10ft swell from the WNW with a 15-second period and combined energy of 4900 (very strong). That’s expert-only territory—too big for the break and conditions are onshore. Skip it.

So overall: a couple of clean morning windows on the 29th and 30th of August, plus the Sunday the 6th of September as the real prize. The rest is wait-and-see.

Rusty.
