The Lowdown
Alright, surfers, Rusty here. Let’s get into it for Lacanau Ocean. The next 16 days are a proper mixed bag, with a couple of real windows of opportunity, but you’ll have to be patient and pick your moments.
The opening stretch is pretty underwhelming. We’ve got a bit of swell pushing in from the WNW this Sunday (30th August), around 5ft, but the wind is onshore or cross-on, making it messy. The energy is weak (333) and the water is much warmer than normal at 75°F, which is a bit of a talking point for the first dip. Monday (31st August) picks up a little more size to 6ft, and the energy ramps up to a moderate 567, but again, the wind is onshore and choppy. It’s just not clean.
The first real standout comes on Tuesday morning, 1st September. The swell drops to 4ft from the WNW, but the wind swings to a light cross-offshore from the NNE. That’s the key. The energy is moderate (301) and the conditions are clean. This is your best bet for the first week – a solid, surfable morning.
After that, the surf goes flat and weak for several days. Wednesday and Thursday (2nd & 3rd September) are tiny, with energy readings dropping below 100. We’re looking at a dry spell until Friday, 4th September, which sees a jump in energy to 188, but the swell is long-period (14s) from the W and only 2ft, with cross-shore wind. It’s not worth the paddle.
Now, hold onto your boards, because the highlight of the whole forecast is Saturday morning, 5th September. The swell fills in at 6ft from the WNW, with a very long period of 13 seconds. The energy is strong (1164). The wind is a light cross-offshore from the NNE, and the call is for excellent conditions. This is a proper groundswell, so expect long, powerful lines. It’s going to be a bit big for beginners, but for the experienced crew, this is the session to target. Just be aware, with a long period like that, the sets will have some good gaps between them.
Sunday morning, 6th September, is a nice follow-up. The swell drops to 4ft from the NW, the wind is offshore from the E, and the energy is moderate (263). It’s clean and surfable, but a step down from the Saturday peak.
The second week gets quiet again. From Monday, 7th September, through to the end of the forecast on Monday, 14th September, the swell is small and inconsistent. There are a few moments with clean conditions, like the glassy morning on Sunday, 13th September, but the swell is only 3ft. The energy is low. It’s a long stretch of small, weak surf. The best you can hope for in that second week is a sneaky clean session on a longboard, but nothing to get excited about.
The true standout is Saturday morning, 5th September. Get on it.

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.
