The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Boucau over the next couple of weeks.
Right off the bat, the first few days are a bit of a write-off. The swell is there on Thursday the 20th, with a 4ft NW swell and moderate energy (384), but the wind is on it and cross-on, making for a choppy mess. Friday the 21st has a bit more size, up to 6ft, but again cross-on wind ruins the surface. You’d be battling more than surfing.
The first real standout is Saturday morning, the 22nd. We’ve got a clean 4ft NW swell, with the wind swinging offshore from the east. That’s 12 mph keeping things hollow and clean. The energy is moderate (241) and the period is a short 9 seconds, so it’ll be a bit crumbly, but it’s your best bet for a fun session without the washing machine effect. Boucau is an exposed W-facing spot, so this NW swell is doing its job. The water is a balmy 77°, which is much warmer than normal for this time of year.
From Sunday the 23rd through Monday the 25th, the swell drops right off. We’re looking at tiny waves, under 2ft, and mostly poor conditions. Tuesday the 25th is almost flat. That’s a gap of about three days with nothing worth paddling out for.
Things start to look up again on Wednesday the 26th of August. The morning session shows a clean 4ft WNW swell, with light cross-offshore wind and moderate energy (241). It’s not huge, but it’s clean and rideable.
Then, hold onto your leash, because Thursday the 27th morning is a real treat. The conditions are glassy – zero wind – with a 5ft WNW swell. That’s clean, lined-up waves with moderate energy (284). The period is short at 8 seconds, so expect some fat sections, but in those glassy conditions, Boucau will be a pleasure.
But the absolute best of the whole forecast is Friday the 28th of August. The morning session is looking like a dream: flat calm, glassy conditions, and a 6ft WNW swell (643 energy). The period is a nice 10 seconds, so it’s got some push. This is the kind of morning you call in sick for. However, this is a solid 6ft, so it’s getting into the territory where beginners might struggle. The afternoon goes to crap with cross-on wind, so get your fill early.
After that, Saturday the 29th and Sunday the 30th have some size, but the wind is mostly onshore or cross. Sunday morning the 30th has a clean 5ft NW swell with offshore easterly wind, but it’s not a standout compared to the Friday.
The first week of September sees a few pulses of 6ft NW swell, but the wind is always on it or cross-on, so the quality is poor. The last few days of the forecast drop back to tiny, messy waves, so don’t hold your breath for the second week.
In short: Saturday the 22nd is the pick for a clean, fun session, but Friday the 28th morning is the absolute standout – glassy, solid, and clean. Get it while you can.
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.
