The Lowdown
Alright, folks, Rusty here. Let me tell you what’s cookin’ for Boucau over the next couple of weeks. It’s a bit of a slow burner, but there are some absolute gems hiding in this forecast.
The pattern starts off a bit average, but don't let that fool you. The first real taste of something good comes on Monday the 14th of September with a morning glass-off. The wind’s barely a breath from the ENE at 3 mph, and the water is a lovely 72°, which feels a touch warmer than usual for this time of year. The swell is a clean 4ft from the NW with a nice 11-second period. It’s not huge, but for a Monday morning when the crowds are sometimes there, it’s a great way to start the week. The combined energy is sitting at a solid moderate level (414), so expect some nice, workable waves.
Honestly, after that little burst, things go a bit flat with onshore slop from Tuesday through to Wednesday afternoon. Not worth paddling out for.
Then we get a fun run from Thursday the 17th of September morning. Another glassy start with a light S wind at 3 mph. The swell has built to 6ft from the NW, still with that punchy 11-second period. The energy is up to (663), a solid moderate push. That early session is going to be a proper highlight before the wind switches.
Now, Saturday the 19th of September is where this whole forecast starts to show its teeth. Mark this one down. The morning brings clean offshore wind from the East at just 3 mph. You’ve got a solid 7ft NW groundswell, with a lovely long 13-second period. This is a point-break friendly swell. If you’ve got a reef or river mouth in mind, this is your window. The energy readings are strong at (1514). This is proper, powerful surf for experienced surfers only. The conditions will be clean and lined up.
After a so-so Sunday, the real standout drops on Monday the 21st of September. Holy moly. This is the session you wait all year for. Glassy conditions again with a tiny NE breeze. A serious 7ft NW groundswell with an even longer 14-second period. The combined energy is roaring at (1641). This is not beginner territory. This is made for the crew who know what they’re doing. The swell direction is right in the zone for Boucau, and with that offshore glass, it will be world-class.
The waves back off a bit mid-week, but there’s another cracker on Friday the 25th of September. Glassy morning with a clean 5ft WNW groundswell. The period is a very long 15 seconds here, so again, look for the points or reefs where the power can line up properly. Energy is high at (993).
The very end of the run into the 28th and 29th gets messy with strong onshore winds. A bit of a washout to close the fortnight.
So, what’s the call? There are two absolute standouts here. Saturday the 19th of September morning is your first big, clean, solid day. But if you want the best of the best, the Monday the 21st of September morning is the one. Big swell, perfect wind, and that long-period power. Get on it.
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.
