The Lowdown
Alright, Rusty here. Let’s get into it.
First up, we’ve got Boucau. It’s an exposed spot, picking up a solid NW groundswell, and it’s a fairly consistent break. The water is sitting at 74°F which is much warmer than normal for this time of year – a real treat. The best of the action kicks off Sunday morning, the 6th of September. We’ve got a clean 5ft NW swell running with a nice 12-second period, and the wind is a light cross-offshore from the ESE at just 3 mph. That’s going to set up some proper, clean walls. The combined energy is moderate (661). This is the standout session of the whole forecast. The crowd factor is a “sometimes” here, so it might get a little busy, but with conditions this good, it’s worth the company.
Monday the 7th drops off. The swell fades to 2ft, and the wind swings onshore from the WSW. It’s a write-off, honestly. Things don’t look much better for a few days, but keep an eye on Tuesday morning the 8th. The wind goes dead calm, glassy, with a 3ft WNW swell (11-second period). The energy is weak (226), but the glass-off could make for some fun, small waves if you’re desperate for a paddle.
After a long stretch of poor, onshore conditions, we get another window. Sunday morning the 13th of September sees a return of glassy conditions with a 3ft NW swell, but this time the period is a solid 12 seconds. The energy is moderate (328). It’s small, but clean. The next real highlight is Wednesday morning, the 16th of September. The swell picks up to 5ft from the NW with a 12-second period, and the wind is glassy from the WSW at just 3 mph. The combined energy jumps to 585 (moderate). This is the second best session on offer – clean, with a bit more push.
The rest of the window is a mix of onshore wind and low energy. The swell stays small, barely breaking 3ft, and the wind is mostly cross-on or onshore. There’s a very glassy morning on the 20th, but the swell is only 1ft, not worth the effort.
To be honest, the real juice is that Sunday morning on the 6th and the Wednesday morning on the 16th. Everything else is a gamble on the tide and a bit of a fight with the wind. For a spot that’s usually fairly consistent, this is a patchy run, but those two windows are worth marking on the calendar.
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.
