The Lowdown
Alright, Rusty here. Let’s have a look at what’s in store for us over the next couple of weeks.
We’ve got a bit of a slow start, but there’s a proper window of clean, fun surf to aim for. The first real standout is Tuesday morning, September 1st, at Lacanau Ocean. The swell is a solid 5 ft from the WNW, with a nice 10-second period, and the wind is a light cross-offshore from the NE at 6 mph. The water is sitting at 74°, which is much warmer than usual for this time of year, so you’ll be comfortable in a spring suit. The combined energy is moderate at 356, and it’s going to be clean. This is the pick of the early period.
After that, things drop off. Wednesday and Thursday are small and messy with onshore winds, and Friday morning, September 4th, offers a tiny 2 ft wave with glassy conditions, but it’s just too small to get excited about. The weekend isn’t much better, with a bit of a bump on Saturday morning, September 5th: 3 ft from the WNW with a 10-second period and a clean cross-offshore wind, but the energy is moderate at 175. It’s surfable, but nothing special.
The middle of the week is a write-off. We get a few days of onshore winds and choppy conditions, with a brief pulse on Monday, September 7th, that’s let down by a strong onshore wind and a short, messy 6-second period. The energy is moderate at 139, but it’s not a paddle surfer’s friend.
We then have a long gap of quiet, small surf until the second week. The only flicker of interest is Tuesday morning, September 15th, with a 3 ft swell from the W, 12-second period, and a clean cross-offshore wind from the ENE at 12 mph. The combined energy is moderate at 295, and it’s marginal but could be a session if you’re desperate.
The real long-range promise lands on Wednesday morning, September 16th. The swell jumps to 6 ft from the W, with a short 7-second period, and the wind is a clean cross-offshore from the NE at 9 mph. The energy is strong at 316. It’s going to be a bit raw and fat with that short period, but the size and clean wind make it the best option in the second week. Keep in mind this is a long way out, so it’s promising but not locked in yet.
Overall, Tuesday morning, September 1st, is your best bet by a long shot. The other days are for the dedicated or the desperate.

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.
