The Lowdown
Alright folks, Rusty here. Let's take a look at what's on the table for Boucau over the next couple of weeks. It's a bit of a slow burner, so don't get too excited just yet.
We're kicking off on Sunday the 23rd of August, but honestly, it's a tease. There are small waves around 2ft from the northwest, but the real story is the water. It's sitting at 77°, which is a massive 6° warmer than usual for this time of year – that's very unusual, and it's a pretty nice thing to have. The problem is, that tiny swell is only carrying weak energy (62) and while the early morning is glassy, the wind is supposed to swing around and junk it up. It's a no-go for a proper session.
From Monday the 24th right through to Saturday the 29th of August, it’s a pretty barren run. The swell stays tiny, under 1ft for most of it, and the winds are all over the place – cross, onshore, choppy. There's a little blip on Thursday morning the 27th with a glassy 3ft from the WNW and a jump in energy to 158, but it's still pretty ordinary. Then Friday the 28th sees a jump in height – 7ft to 8ft from the WNW – but the wind is cross-onshore and it’s messy. The energy readings are high (804 and 1822), but that won't matter much with the wind messing it up. This whole stretch is a write-off for a decent paddle.
Now, Sunday the 30th of August is where we finally get a sniff. The morning shows a clean 4ft from the NW with a light offshore easterly breeze at 6 mph. The energy is moderate at 201, and the conditions are looking clean. This is the standout for the whole forecast period. It's not huge, but with offshore wind and that NW swell, it'll be the best on offer. Keep in mind, though, that the crowd factor here is listed as "sometimes," so you might have some company.
After that little window, it's back to the grind. Monday the 31st is poor, and through the first week of September the wind is mostly onshore or cross-onshore, keeping everything choppy and uninviting. We get another small chance on Wednesday the 2nd of September with a glassy 2ft from the NW, but it's weak (100 energy) and very ordinary. By the 7th of September, we're looking at 4ft to 5ft from the NW, but it's blowing 25 mph onshore, so that's just a complete mess – that setup looks more interesting for kite surfing than paddle surfing.
So, to wrap it up: don't hold your breath for the next week. Your best bet is the morning of Sunday the 30th of August. After that, the long-range outlook for early September looks poor and unreliable.
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.
