The Lowdown
Alright, Rusty here, let's talk about what's happening at Boucau over the next couple of weeks.
Alright, Boucau’s got a mixed bag coming up. Not a lot of magic on the immediate horizon, but there are a few windows that look worth getting excited about. The real standout moments are going to be later in the period, so keep your eyes on the calendar.
The first few days are a bit of a write-off. Monday the 7th and Tuesday the 8th are looking pretty ordinary with onshore winds and weak, messy surf – not worth paddling out for. Wednesday the 9th brings a bit more size, around 6ft, but it's a short-period (9 seconds) windswell, and the cross-shore wind won't do it any favors. The energy’s moderate (475), but the quality is poor.
Things start to look up on Thursday the 10th of September. That morning is a beauty – glassy conditions with a clean 4ft northwest swell. The period stretches out to 10 seconds, and the energy is moderate (355). That’s the first real highlight, with clean, fun waves on offer. The wind is dead calm from the ENE, so it’ll be smooth.
Friday the 11th drops right back down, tiny 2ft surf and glassy, but it’s just too small to get excited about. Saturday the 12th is even smaller. We have a quiet few days until Sunday the 13th of September. That morning looks promising again: glassy, a clean 4ft swell, but look at that period – 13 seconds (a nice groundswell) and the energy jumps to 489 (moderate). This will have some real push. The afternoon gets a little bigger at 5ft, but the cross-onshore wind messes it up.
Now, for the absolute best of the forecast: Monday the 14th of September. The morning is a gem. You’ve got a clean 5ft northwest swell, period of 12 seconds, and the energy is strong (603). The wind is zero – dead calm from the NE, glassy. This is your top pick for the whole outlook. It’s a powerful, clean groundswell that will break well, though with that longer period, the bigger sets might be a bit straight at the beach. Still, for an advanced break, this is the session. The water temp is about average for this time of year.
Tuesday the 15th and Wednesday the 16th are worth a look in the mornings only (glassy), but the best windows pass by quickly. Thursday the 17th morning is another clean one: 5ft, 10-second NW swell, moderate energy (442), and glassy. Solid fun.
But if you’re waiting for the next real standout, look at Friday the 18th of September. Another morning where the stars align: a clean 5ft northwest swell, period of 10 seconds, energy at 509 (strong). Flat calm, zero wind from the north, glassy. This is another one to circle on the calendar. It’s over a week away, so it’s a promising outlook, but not locked in.
The rest of the run into the 22nd is small and clean but unspectacular. Saturday the 19th morning could be okay with clean 4ft surf, but the afternoon brings rain. Monday the 21st and Tuesday the 22nd are tiny with clean offshore wind, surfable but nothing to write home about. The last week does have potential, but it’s all a bit of a waiting game for the real goodness.
So, to sum it up: the best waves on offer are the mornings of Monday the 14th and Friday the 18th of September. Don't sleep on those. Everything else is either messy or too small.
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.
