The Lowdown
Alright folks, Rusty here. Let's talk about the surf ahead. The start of this run is pretty much dead, so don't rush to the water just yet. The ocean is a warm 75°F, which is much warmer than normal for this time of year, so boardshorts are the call.
Your first real chance for a wave is this Saturday morning, September 5th. After a flat and messy first few days with dribbly 2ft to 3ft waves and wind all over the shop, we finally get a clean window. Saturday morning is glassy with a clean 4ft of west-northwest groundswell, a long 14-second period, and a combined energy of 676. It’s an exposed spot, and that swell direction is perfect. It’s going to be fun, but it gets chopped up in the afternoon when the seabreeze kicks in.
Sunday morning, the 6th, is the standout of the first week. Another glassy morning, with a touch more size at 5ft, a 12-second period, and energy up to 723. This is the one to get. The waves will have some grunt. This is an advanced break, and with those kinds of waves on an exposed bank, it will have some real power. Anyone under an intermediate level should be sitting this one out.
The surf then backs off again for the rest of that week and into the next. We're talking a lot of days struggling to hit 3ft with onshore winds. The 10th and 11th have some small surf, but the wind is dodgy.
Now for the long-range. Looking all the way out to Tuesday, September 15th, the models are hinting at a solid pulse of groundswell. It's far out so take it with a grain of salt, but the potential is there for something special. We’re talking 7ft of west-northwest swell on Tuesday morning, with a long 14-second period and a powerful energy reading of 1453. That’s a serious amount of water. This is definitely expert-only country given the size, and the light south-west wind forecast isn't ideal. With a swell that size and that long period, this exposed beach break could get pretty shifty and heavy. It might well be more of a spectacle than a surf session for most.
So, short term, get on it this Saturday and Sunday morning. Long term, the 15th is the one to watch, but be ready for it to be a beast. Keep an eye on the forecast between now and then.
Rusty, signing off.

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.
