The Lowdown

Alright, Rusty here. Let’s have a look at what’s cooking for Boucau over the next couple of weeks.

Alright, the good news is there’s a solid window of surf coming up, but it’s not a straight run of perfection. We’ve got a bit of a wait for the real standout, so let’s talk it through in order.

The session to really circle on the calendar is Saturday morning, August 29th. That’s the pick of the bunch. We’ve got a clean 6 ft swell rolling in from the WNW with a 9-second period, and the wind is a light 3 mph easterly, keeping it glassy. The water is sitting at 75°, which is a very unusual 5° warmer than normal for this time of year, so you can leave the wetsuit at home. The combined energy is moderate (641), so there’s plenty of push. For an advanced break like Boucau, this is as good as it gets. Expect it to be a bit of a party though – it’s sometimes crowded, so get in early.

Sunday morning, August 30th is the next best thing. Still a clean 5 ft swell from the NW, 10-second period, and the wind is completely calm – glassy as a mirror. The energy is moderate (368). A proper, fun morning session.

After that, the pattern gets a bit messy. The rest of the first week and into the start of September, we’ve got a mix of cross-onshore winds and questionable conditions. The swell hangs around in the 4 ft to 5 ft range, but the wind is never quite right. The afternoons are particularly rough with a NW breeze picking up, making it choppy. The mornings on Tuesday, September 1st and Wednesday, September 2nd are glassy, but the swell drops off to 5 ft and then 3 ft, so it’s just ordinary waves.

We hit a flat spell from Thursday, September 3rd through to mid-week the following week. The swell drops to near nothing, and the wind is mostly onshore or cross-onshore. It’s not worth paddling out for.

Then, a bit of a late surprise. Saturday morning, September 5th brings a clean 3 ft swell from the NW with a 10-second period, and an offshore easterly breeze at 6 mph. The energy is moderate (258). It’s small but clean. The afternoon sees a big jump in period to 14 seconds and a 5 ft swell, but it’s a cross-shore wind, so it’ll be a bit bumpy. That long period (14 seconds) is a proper groundswell, which will make it a bit walled at a beach break, but there’ll be some power.

Sunday morning, September 6th is also clean, with a 4 ft swell from the NW, 11-second period, and a light offshore. Moderate energy (338). A nice, clean morning option.

The last week of the forecast is a write-off. The swell drops to under 3 ft, the wind is mostly onshore or cross-onshore, and the period gets short. It’s a flat, blown-out end to the run.

So, to sum it up: Saturday morning, August 29th is your absolute best bet – big, glassy, and warm. Sunday morning, August 30th is a close second. After that, pick your moments for the clean mornings, but don’t expect much until the flat spell is over.

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.
