The Lowdown
Alright folks, it’s Rusty here, and I’ve gotta be straight with you – the next couple of weeks look pretty grim for a paddle. We’re staring down a long stretch of small, messy, mostly onshore slop before a late window of hope shows up.
The first real chance for a wave doesn’t come until the early morning of Thursday the 20th. Before that, from the 14th right through the 23rd, it’s a whole lot of junk. We’re talking tiny swell under 3.3ft, short periods, and winds that are either onshore or cross-onshore, just chopping everything up. There’s a glimmer of something glassy on the morning of the 18th, but the swell is a pathetic 1.3ft with weak energy (32), so you’re better off taking the dog for a walk. That’s a solid ten-day gap of bad surf.
Thursday the 20th morning finally shows a pulse of 2.0ft from the NW with a period of 9 seconds, and the wind goes dead calm – glassy clean. The combined energy is still only 91, so it’s weak, but at least it’s surfable. This is the definition of a small, clean, grovel session. The afternoon goes to shit though, so get it while you can.
The next real standout is a long way off, on the 27th of August. The forecast shows a proper jump in swell. By Thursday morning, we’re looking at 5.2ft from the NW at 9 seconds, with a light ESE wind that’s cross-offshore. The combined energy jumps to 379 (moderate). The afternoon cleans up even more, turning offshore with 4.6ft swell and 286 energy. This is the first decent window in the whole outlook. The conditions are described as clean, which is a major positive after all the wind we’ve had. The water temperature is a very unusual 24.7°C, which is much warmer than normal for this time of year – a nice bonus.
For the standout, it has to be Boucau on the morning of Thursday the 27th. It’s an advanced break, fairly consistent, and exposed to the W. With a 5.2ft NW swell and light offshore/cross-offshore wind, it’ll be offering some solid, hollow waves. The afternoon is also good, but the morning has the cleaner start. Keep in mind, this is a week and a half away, so the details are promising but far from locked in.
After that, the 28th and 29th see a massive amount of energy – we’re talking 769 and 3527 on the 29th – but the wind turns onshore and howling. 9.8ft swell with a 18.6 mph onshore wind at Boucau is a washing machine. That’s kite-surfing territory, not a paddle session.
Hang in there, but don’t get your hopes up for the first ten days.

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.
