The Lowdown
Alright mates, Rusty here. Let’s have a look at what’s cookin’ for Boucau over the next couple of weeks.
I’ll cut straight to it – the first week and a half is a real desert. From Friday the 17th of July all the way through to Sunday the 26th, the surf is just about non-existent. We’re talking tiny scraps, mostly under 3 ft, with onshore or cross-onshore winds messing it up. Even the glassy mornings have nothing to ride. The water is much warmer than usual for this time of year, sitting at 76°F – that’s nearly 7°F above normal, which is pretty wild.
The first real pulse shows up on Monday the 27th of July. Swell hits 4 ft from the NW with a 9-second period, and the combined energy is 309 (moderate). But the wind is cross-on from the WNW at 6 mph in the morning, and it picks up and gets choppy later. It’s a marginal call – surfable but not great.
The best bet of the whole outlook is Tuesday the 28th of July. That morning, Boucau goes glassy with a light breeze from the ENE at 3 mph. Swell is 3 ft from the NW at 8 seconds, combined energy 127 (moderate). It’s small, but it’s clean. The crowds are listed as “sometimes,” so you might have some company, but with the size, it should be manageable.
After that, we roll into the first week of August with a bit more juice – 3 ft to 4 ft swells from the NW with 10-11 second periods and combined energy up to 338 (moderate). The problem is the wind: onshore or cross-on from the W and WNW. It’s choppy and messy. The 29th of July morning has a 12-second groundswell, but it’s only 2 ft and the wind is onshore, so it’s a no-go.
So, if you’re looking for a session, lock in Tuesday the 28th of July. It’s the only clean, glassy window in the whole forecast. The rest of the time, it’s a waiting game.
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.
