The Lowdown
Alright folks, Rusty here. Gotta be honest, the next couple weeks are gonna test your patience. There’s a lot of flat, junky ocean out there. For the next several days, the swell is weak, the winds are messy, and it’s not worth the paddle. You’d be better off hanging in the parking lot.
We have a few small, weak pulses mid-week, but they’re short-period and choppy. It’s just a poor run of form. There’s a stretch of several days with nothing on offer.
But then, the tide starts to turn. The morning of Tuesday, September 1st has a bit of hope. A new swell is due with head-high waves around 6ft from the northwest, and the wind is forecast to be calm and glassy. It’s the first clean window we’ve seen. The wave energy is building to a moderate level (535) and the surface looks like a pond. It’s not a monster, but it’ll be fun and clean. That’s your morning to be at Boucau. Once the afternoon wind gets up, it’ll turn to junk.
Don't get too stoked for the next few days after, though. We slide right back into ordinary, messy conditions.
The big one, the one to plan for, is the morning of Sunday, September 6th. That’s when we get a proper pulse. We’re looking at waves in the 7ft range from the northwest, and again, the wind is looking glassy in the early hours. The energy is strong (911). The water is running at 76°F, which is about 5°F warmer than normal for the season. That’s notable. Expect powerful, lined-up surf. It’s a week and a half away, so call it promising, not a guarantee. The direction is right on for Boucau, and while 6ft might be too much for the beginners, it’ll be a proper session for anyone with a bit of go. That’s the standout of the month.
Then, Monday morning the 7th could be a bonus. It’s a smaller pulse, around 4ft, but it’s a long-period groundswell with 16-second intervals. That’s a lot of energy. The winds are forecast to be light and offshore, which would make it clean and lined up. Just keep in mind, those long-period swells can make beach breaks close out a bit, so you might need to find a bank that’s holding.
So there it is. A lot of nothing for the next week, but two definite mornings to mark: the 1st and, if you can wait, the 6th. Water’s warm, there’s potential on the horizon, we just gotta be patient.
Stay stoked.
Rusty.

Information about the Boucau Surf forecast
The above surf forecast table for Boucau provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Boucau can be found by selecting the local surf guide option on the grey menu. Our Boucau surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Boucau) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Boucau may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Boucau is 5 km (3 miles) from Biarritz. If you plan a holiday in Landes, look for hotels and other accommodation in Biarritz. Biarritz has rooms for a wide range of budgets as well as car hire and transport links.
