The Lowdown
Alright, Rusty here. Let’s break it down.
We’re talking Boucau, and the first few days are a bust. Friday, August 28th, is no good – 1.5m to 1.7m of messy swell with onshore winds. The energy is moderate (289-383), and the water is 75°, which is much warmer than usual for this time of year. That’s something to note.
Saturday morning, August 29th, is where it gets interesting. 1.9m from the WNW, but the wind goes glassy, light offshore from the east. The combined energy hits 641, and the waves will be clean. The period is 9 seconds, so it’s a short period windswell, but with glassy conditions, it’ll be a fun session.
Sunday morning, August 30th, is another good one. 1.7m from the NW, period 11 seconds – that’s a proper groundswell. Glassy again with an easterly offshore. Energy is 664. Clean, solid, and better shaped waves. This is a standout.
Monday morning, August 31st, and Tuesday morning, September 1st, both offer glassy mornings with 1.5m. Energy is moderate (373-432), period 9-10 seconds. Clean and rideable for a weekday paddle.
The big one is Saturday morning, September 5th. 1.8m from the NW, period 13 seconds – long-period groundswell. Energy jumps to 1021, strong wave energy. Wind is glassy, light offshore from the southwest. The forecast says excellent for experienced surfers. This is the best on offer, but it’s a week out, so it’s a promising long-range call.
After that, the surf drops off. From Sunday, September 6th, through to the end on September 12th, it’s mostly small, weak, and messy. A few glassy mornings (like September 8th and 11th), but the swell is tiny – 0.6m to 1.0m – not much to get excited about.
So, the best bets are Saturday 29th and Sunday 30th August mornings, and the standout is Saturday 5th September morning. Get out there when it’s clean.
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.
