The Lowdown
Alright, let’s break down what’s heading for Boucau over the next couple of weeks.
It’s a slow burner, to be honest. The first few days are ugly – onshore wind and messy surf, no good. You’ll be sitting on the beach until the morning of Wednesday, September 9th. That’s when a clean 6ft NW swell shows up with a light offshore breeze, and the energy is pumping (540). It’ll be proper lined up. Just get it in the morning because the wind goes cross-shore and messes it up by the afternoon.
Thursday the 10th is a beauty. The swell drops a touch to 4ft from the NW, but the wind is totally glassy. Dead calm. It’s going to be clean as a whistle, with moderate energy (318) giving you some fun, rideable waves. That morning is the clear winner of the first week.
The weekend and the start of the next week are pretty weak. Small, onshore, and not much going on. There’s a pulse of long-period groundswell on Sunday the 13th – 5ft NW with a 13-second period and a big energy spike (663) – but the wind is on it, so it’ll be a bumpy mess. Still, if you’re desperate, Monday the 14th morning is glassy again with a clean 4ft NW swell, and that’s probably your next best window.
Then it goes quiet again. Tiny waves and onshore junk until… the morning of Monday, September 21st. That’s the one to keep an eye on. It’s a week and a half away, so don’t get too excited yet, but the forecast is for 5ft NW swell, glassy conditions, and a very strong energy reading (573). If that comes together, it’ll be the best day of the entire outlook. The afternoon gets choppy again, but the morning will be pure gold.
So, the two real standouts are Thursday the 10th morning – glassy, clean, and fun – and the potential of Monday the 21st morning, if the long-range forecast holds up. The rest is mostly small and choppy, or just flat.

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.
