The Lowdown
Alright, Rusty here. Let's break down what's happening at Boucau for the next couple of weeks.
Straight up, the first week or so is a total dud. We’ve got a slow start, and there’s not much to write home about until the very end of the month. The water is sitting at 77°F, which is much warmer than normal for this time of year, so at least it’ll feel nice if you’re just floating.
From Saturday the 18th through the 25th, it’s basically flat. We’re looking at tiny swell – 0.7ft to 3ft – with short, weak periods around 5 to 8 seconds and combined energy barely cracking 100 (10-111). The wind is all over the place, mostly onshore or cross-on, making for messy, poor surf. Not worth paddling out for.
There’s a small window on Tuesday morning the 21st where it goes glassy, but the swell is still only 3ft with a 6-second period, and the energy is weak (84). It’s surfable, but it’s very ordinary. You won’t miss anything.
Things stay in that same poor-to-marginal range through the 26th, with the swell barely pushing 4ft. The wind is mostly onshore, and the energy is still low. It’s a tough stretch.
Now, here’s where it gets good. The standout is Monday morning, the 27th of July. The swell hits 4ft from the NW, but the real story is the period – 10 seconds – and the combined energy hits 308. That’s moderate, solid energy. The wind is glassy from the NNW, so it’s going to be clean. This is the one to wait for.
The real highlight, though, is shaping up for the end of the month and into August. On Friday afternoon, the 31st of July, we’ve got a 5ft NW swell with a 10-second period and a combined energy of 507 – that’s strong wave energy. The wind goes glassy, and the forecast is for very good surf conditions. This looks like the best session on offer.
That energy carries over into Saturday morning, the 1st of August, with another 5ft NW swell, 10-second period, 508 energy, and glassy conditions. Another cracker. Just keep in mind, the swell is pushing 5ft, so it’s getting a bit chunky for beginners, but for anyone with a bit of experience, it’s going to be fun.
The rest of the first week of August looks like it’s fading, with the wind turning cross-on and the energy dropping off. So, the real window to target is that Monday the 27th, and then the Friday 31st and Saturday 1st of August. Get on it if 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.
