The Lowdown
Alright folks, Rusty here with a look at what's coming our way for the next couple of weeks. We’ve got a bit of a slow start, but there are some absolute crackers on the horizon, so don’t write this one off.
Right now and through the middle of the week, it’s pretty grim. The wind is howling from the west and onshore, with only small, weak swell. The water temperature is sitting at a very toasty 73°, which is much warmer than normal for this time of year at Boucau. You can leave the steamer at home, that's for sure. But honestly, the combo of onshore wind and weak energy means it's not worth paddling out. We've got a few days of this poor stuff to sit through.
Now, Thursday the 17th morning is where things start to get interesting. The wind drops right out and goes glassy, and we see a solid NW groundswell push in at about 6ft with an 11-second period. The energy jumps up to a solid moderate level. This is the first real glimpse of something good, and it’s going to be clean.
But the real standout, the one you want to circle on the calendar, is Saturday the 19th. That morning is looking absolutely firing. We get a glassy-offshore easterly wind, and a proper NW groundswell at about 7ft, with a pumping 13-second period. The combined energy is strong and powerful. This is excellent surf for experienced surfers only. It’s going to be big, powerful, and clean. If you’ve got the skills, this is your window. Be aware, with conditions this good, it might get a little crowded.
Sunday the 20th and Monday the 21st mornings will offer some more of that lovely glassy wind and clean 5ft to 5ft NW swell, with the period staying long at 11-12 seconds. The energy stays in the moderate range, making for some very good, fun waves that will be a bit more manageable than Saturday.
We then hit a bit of a lull from Tuesday afternoon through the following weekend, with smaller swell and cross-onshore winds mushing things up. The energy dips back down, and for a few days, it’s not really worth the paddle.
Then, look ahead to Tuesday the 30th of September. This is another promising one. We see a clean, glassy morning with a fresh NW groundswell of about 6ft and an 11-second period. The energy is solid. It’s a bit further out, so keep an eye on the forecast, but this has the potential to be another great, clean day at Boucau.
So, in short: sit out the first few days, smash it on Saturday the 19th morning, enjoy the cleaner leftovers on Sunday and Monday mornings, and then keep an eye on the 30th.
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.
