The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Boucau.
Right off the bat, the next few days are a bit of a write-off. We’ve got a small, weak swell hanging around, but the winds are just all over the place. The water is sitting at a very unusual 77°, which is much warmer than normal for this time of year, so if you’re just getting wet it’s pleasant enough, but the surf is not worth paddling out for.
Things start to show a little life on the morning of Saturday the 22nd. The wind goes glassy out of the ENE at only 3 mph, and we get a clean 4 ft NW swell. The combined energy is moderate (241), and it’s just enough to make it surfable. It won’t be pumping, but that window of dead-calm conditions is your best bet for a longboard or a funboard.
The real standout, the one to circle on the calendar, is Wednesday the 2nd of September. This is the pick of the whole run. The morning kicks off with a clean 6 ft NW groundswell (10-second period) and a light, cross-offshore breeze from the ESE. The energy is solid (664), and by the afternoon the wind goes totally glassy. You’re looking at clean, lined-up waves that are going to be fun for a decent crew of surfers. It’s not a massive swell, but the quality will be there. Crowds are sometimes an issue here, so keep that in mind.
After that, the window closes again. The end of August and the start of September bring some serious size. On the 31st of August we see a big 10 ft NW swell (12-second period) rolling in, and it gets even bigger on the 1st of September with 12 ft. That’s expert-only territory at this break, and the cross-onshore winds will make it messy and dangerous.
Overall: If you can get out on the morning of Saturday the 22nd for a small, glassy session, go for it. But the real gold is waiting on Wednesday the 2nd of September. That’s the day to clear your schedule.

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.
