The Lowdown
G’day, Rusty here. Let’s scope out the next couple of weeks at Boucau.
It’s a quiet start. The first decent action arrives Saturday morning, September 5th, with a 3ft NW swell, period around 9 seconds, and a clean offshore ENE breeze. The combined energy is moderate at 229, so there’s some drive. Water temp is 74° – that’s much warmer than average for this time of year, so you’ll be comfy in trunks.
That Saturday morning is the early pick – clean waves and offshore wind. The afternoon gets messy with a cross-shore wind and a 5ft swell with a 13-second period, turning it choppy.
Sunday the 6th has a 5ft NW swell with a long 12-second period, but the wind is onshore from the WNW. It’s okay, not special.
The real gem is Wednesday morning, September 9th. The wind goes glassy with a light NE breeze, the swell is 3ft from the NW with a sweet 12-second period. Energy is moderate at 331, and the surface is like glass. That’s the session to aim for.
Thursday the 10th is also glassy in the morning with a 4ft NW swell, 11-second period, and 332 energy – another top call.
After that, a bit of a lull with onshore breezes and small stuff until Friday the 18th. That morning sees a solid 5ft NW swell, 11-second period, and a clean cross-offshore NE wind. Energy is strong at 584, making for some really good waves. Then Saturday the 19th of September goes glassy again in the morning, with a 5ft NW swell, 10-second period, and strong energy at 529. That Saturday morning is the other standout – clean, punchy, and definitely worth the wait.
Crowds? Boucau can get busy sometimes, but with waves like these, you’ll be sharing the stoke.
Rusty out.

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.
