The Lowdown
Alright folks, Rusty here. Let’s get into it.
The coming week at Boucau is a bit of a mixed bag with a few standout windows that are going to be worth your time. The water is sitting at about average for this time of year, nothing wild happening there.
The first real action comes on Thursday morning, the 10th of September. We've got a clean 4ft NW swell pushing through, with a light offshore breeze from the ESE at just 6 mph. The waves are going to be well-shaped, with the energy reading a moderate 311. This is a solid option for a morning session.
Friday morning the 11th is a dud. The swell drops to 2ft, and while it’s glassy, it’s just too weak (energy 83) to get excited about. The afternoon is a washout.
Saturday the 12th offers a small, clean 3ft WNW swell in the morning, but it’s marginal. Save your energy for what’s coming.
Sunday morning, the 13th of September is the standout. This is the one you’ve been waiting for. A beautiful 4ft NW groundswell, with a very long period of 13 seconds, is going to be rolling in under glassy conditions. The combined energy is a solid 600, so there’s real power in the water. The wind is dead calm, so you’re looking at absolute perfection. This is a top-tier window for advanced surfers, that long period will make the waves wedge up nicely.
Monday morning the 14th is still a good call, with 4ft NW swell and glassy conditions, but the combo is a step down from Sunday. The energy is 427.
After that, the week turns into a waiting game. The 15th through the 18th are mostly small, choppy, or onshore, with nothing to write home about.
Saturday the 19th of September has a glimmer of hope with a glassy morning and 4ft NW swell, but the period is a short 8 seconds, so it won’t have the same punch. The energy is still moderate at 207.
Sunday the 20th sees another clean, glassy morning with 4ft NW swell. The period is a better 10 seconds, and the energy is 362. A decent option for the weekend if you’re keen.
Don’t bother with the 21st through the 23rd – it’s onshore mush.
The long-range potential is on Thursday the 24th of September. The forecast shows a 3ft WNW groundswell with a very long period of 14 seconds, and it’s looking glassy in the morning. The energy is 410. It’s three weeks out, so keep an eye on it, but it could be a nice clean day.
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.
