The Lowdown
Alright, crew, Rusty here. Let's look at Boucau.
The start is weak. Saturday the 12th is small with 2-ft waves from the NW. The water is a warm 73°, which is much warmer than normal. Nothing exciting.
Then it gets good. Sunday the 13th morning is the first real call. We get chest-high 4-ft NW groundswell with a 13-second period. The combined energy is a moderate 545. And the wind? Dead calm, glassy. That's clean, lined-up surf for the advanced crew. Get out before the wind shifts.
Saturday the 19th of September is the standout. Early morning it’s firing: 6-ft NW swell with a long 13-second period and a combined energy of 1136 (strong). That’s powerful, expert-only surf. The wind is glassy again. For a NW-exposed spot, that’s prime. The afternoon will get blown out.
Later in the window, Thursday the 24th afternoon is another good call. Glassy conditions, 4-ft NW groundswell with a 13-second period and a combined energy of 545 (moderate). It’s a promising end to the forecast, but it’s a week and a half out, so don’t set your watch by it yet.
The pick of the lot is that Saturday the 19th morning session.

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.
