The Lowdown
Alright, Rusty here, let’s talk about what’s happening at Boucau over the next couple of weeks.
The start of the forecast is a bit flat. We have to wait until the 1st of September, but that Tuesday afternoon is a total loss – poor surf and cross-shore winds. The real action starts on Wednesday the 2nd. That morning is glassy with a clean 0.9 ft NW swell. It’s surfable but very ordinary, with weak energy (120). Good for a paddle, not for a barrel.
Thursday the 3rd morning is a real standout. A light 6 mph offshore easterly, clean faces, and the swell is only 2 ft from the NW, but the conditions are pristine. For a longboard, this is your moment. The water temp is 74°, which is much warmer than usual for this time of year (a positive anomaly of 4°), so no wetsuit needed.
We roll through a few more small days. Friday the 4th morning is clean with a light offshore and 2 ft from the WNW, but it’s tiny. Saturday the 5th morning is glassy with a 3 ft WNW swell, still nothing major.
Now, circle Sunday the 6th of September. That morning is the best of the whole outlook. We’ve got 4 ft of NW groundswell with a very long period of 12 seconds. That long period brings real energy and shape, with a combined energy of 494. It’s glassy, with hardly any wind from the NW. This is the session. Boucau faces W swell, so the NW direction is a little off, but the wind and quality make it your top pick.
After that, the following week gets messy with onshore winds. The 10th of September Thursday morning has a nice window – glassy and a clean 4 ft NW swell (326 energy). That’s another solid morning.
For the second week, things look less promising. Even with some offshore east winds on the 12th and 14th, the swells hang around 3 ft to 4 ft, and the winds often turn onshore later. Monday the 14th afternoon is the most interesting of the second week: a 6 mph offshore easterly with a clean 4 ft WNW swell. But the period drops to 7 seconds, so it’s weak, short-period windswell.
Bottom line: Sunday the 6th morning and Thursday the 10th morning are your best bets. Get on that groundswell on the 6th – that’s the one.
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.
