The Lowdown

Alright folks, Rusty here, checking in with the long-range look for Boucau. Let's be straight with you: there's a lot of quiet days ahead before things get interesting.

It's a slow start. For the first six or seven days we're looking at some seriously small, weak surf with mostly onshore or cross-onshore winds. Don't expect much size at all. The water temperature is sitting around 77°F, which is much warmer than normal for this time of year – that's the standout feature of this early period.

Things begin to change around the morning of Thursday, August 20th. The combined energy jumps from almost nothing to a moderate 149, with a long-period swell of 11 seconds from the NW. The wind is light and cross-offshore, cleaning things up nicely. The waves are still small at 2 ft, but conditions are surfable.

Now, the morning of Friday, August 21st is the real standout in this entire forecast. You get a solid 5 ft of swell from the NW with a long 11-second period. The combined energy rockets to a strong 558. Best of all, a light offshore breeze from the NE (3 mph) will have those waves looking glassy. The guidance gives this spot top marks for a reason. This is a window for advanced surfers to score some proper waves. The afternoon on that same day gets messy, so make it a dawn mission.

The morning of Saturday, August 22nd, offers another good session. It's smaller than Friday, at 4 ft, but with glassy conditions and clean lines from a NW swell (period 10 seconds). The energy is at a solid 210. It’ll be a good one, but Friday morning is your best bet.

After the 22nd, the pattern gets messy again. There’s a pulse on Tuesday morning, August 25th, with a clean 3 ft wave and an offshore easterly, but it’s very ordinary. The next real highlight comes early on Wednesday, August 26th. A clean offshore wind from the East (6 mph) should groom a 2 ft, but very long-period (12 seconds) NW swell. The energy is a solid 266. It's a steep, clean option for the loggers before the wind switches.

The rest of the outlook into the 30th is filled with cross-onshore winds and choppy conditions. A few mornings offer a glimmer with light winds, like Friday, August 28th, but the energy is down and the quality isn't there.

In short: The first week is a write-off. The one genuine standout to pencil in is the morning of Friday, August 21st for size and offshore perfection. Early on the 22nd is a good backup, and the 26th could be fun for those on longer boards.

Stay stoked.
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.
