The Lowdown
Alright, let's break down what's happening at Boucau. Rusty here, and I've got the scoop.
First impression: the water is a balmy 74°F – that’s more than four degrees warmer than what's normal for now, so you can leave the steamer at home. Feels like the tropics.
The start is a slow burn. Don't even think about the 3rd – it's tiny, choppy, and the energy is barely registering at 63. Thursday morning the 4th is glassy with a whisper of offshore wind from the NE, but the swell is a paltry 2ft with a short 8-second interval. You can get wet, but you'll be fighting for nothing.
The first decent window hits Saturday morning, September 5th. We've got a clean 3ft of NW swell, slightly better 9-second period, and dead flat glass from the ENE. The combined energy bumps to 206 – it's moderate, but it's clean. A perfect longboard morning. The afternoon on the 5th gets ugly though – a 5ft NW groundswell (13 sec period) gets hammered by a 20 km/h NW wind. Choppy and blown out. That's kiteboard territory.
Sunday morning, the 6th, is a real banger. You get a clean 5ft NW groundswell with a 12-second interval, combined energy of 661, and a light cross-offshore breeze from the SE. This is good, proper surf. Solid push, clean face, good shape. It's getting up there in size, so this is one for the experienced crew.
Monday the 7th and Tuesday the 8th are messy with onshore winds and cross-chop. We get another clean spell on Wednesday morning, the 9th – a light offshore E wind with a waist-high 4ft NW swell (8 secs). Energy is 201. Small and clean, a fun little session.
The 10th morning is glassy again with a 4ft NW swell (10 secs), energy at 241. Then the middle of the week fades into onshore junk.
Now, Sunday, September 13th is the long-range prize. We're looking at a powerful 6ft NW groundswell, long 13-second period, and total energy of 984 – that's strong to very strong. The morning is glassy with a light NE breeze. This is a serious, powerful swell with long, clean lines. Over 5ft, this is expert-only territory. Mark it down, but it's a week and a half away, so don't bet the farm on it.
After that, the 14th and 15th drop off, but Tuesday morning the 15th is dead calm (0 km/h wind) and glassy with a clean 3ft NW swell – a nice small-wave glass-off session.
The final days look onshore and weak. So, your two real standouts are Sunday morning the 6th for a guaranteed good time, and a hopeful eye on Sunday the 13th for something a bit more serious.

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.
