The Lowdown

Right then, let’s have a look at what’s on offer for Lacanau Ocean over the next couple of weeks.

The first week is a bit of a mixed bag, to be honest. We start off with a tiny bit of swell on the Friday morning, but it’s only 3 ft from the WNW with a short 8-second period, and the water is a very unusual 74°F—that’s 4°F warmer than normal for this time of year, which is notable. However, the wind is glassy from the North at just 3 mph, so the wave energy is weak (76), and the conditions are just surfable. It’s not really worth getting too excited about.

The best bet in this whole run looks like Saturday the 5th of September. Saturday morning brings a clean 3 ft from the WNW with a 9-second period, cross-off wind from the NE at 6 mph, and the energy bumps up to a moderate 272. The waves are clean and the conditions look good for an intermediate surfer. However, by the afternoon the wind picks up to 12 mph from the North, the swell jumps to 4 ft with a long 13-second period, and the energy is strong (587), but it goes cross-shore and choppy, so it’s not as good. Still, that morning window is the standout.

From Sunday the 6th onward, it’s pretty rough. We get a run of poor surf conditions with onshore and cross-onshore winds, and the ocean stays messy right through the following week. There’s a bit of energy here and there, like Tuesday the 8th afternoon hitting 400 (strong), but it’s all wind-affected. The swell stays in the 2 ft to 4 ft range, mostly from the WNW, but the wind just ruins it.

There’s a big gap with nothing recommended for days. The next glimpse of hope comes on the 15th of September (Monday), where we see some clean conditions with cross-off winds from the NE, but the swell is short-period (6–7 seconds) and the energy is just moderate. It’s not great, but the conditions are clean.

The real standout of the entire forecast, and it’s a long way out, is Thursday the 17th of September morning. This one looks pure glass—calm wind, 0 mph from the SE, with a clean 4 ft swell from the WNW at a 10-second period, and the energy is strong (377). The water is likely still warm from that anomaly earlier. This is the session to circle on the calendar, but it’s far out, so keep an eye on it.

For the rest of the second week, it’s mostly small, clean but weak, or messy. The crowds at Lacanau Ocean are sometimes a factor, so if you do get that Thursday morning, get out early.

Alright, that’s the story. Keep your wax fresh and your eyes on the 17th.

Information about the Lacanau Ocean Surf forecast

The above surf forecast table for Lacanau Ocean provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lacanau Ocean can be found by selecting the local surf guide option on the grey menu. Our Lacanau Ocean 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 (Lacanau Ocean) 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 Lacanau Ocean 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.
