The Lowdown
Alright, folks. Rusty here again, breakin' it down for you in feet and miles. Looking at the outlook for Lacanau Ocean, the first week is a real bummer. We’ve got a long dry spell with nothing worth wetting a wetsuit for.
The first flicker of hope comes early on Friday, August 7th. There’s a tiny 2ft NW swell with a short 6-second period, giving us weak energy (51). The water is a warm 76°F, which is a massive 5°F warmer than normal – that’s very unusual, feels like a bathtub. The wind is a light offshore from the NNE, which is nice, but the swell is just too tiny and weak to bother. Then it’s a ghost town. From Friday afternoon all the way through Thursday the 13th, the conditions are poor. Tiny, weak swell and cross-onshore winds making it a choppy, messy soup. That’s nearly a week of nothing.
We get a little pulse on the morning of Friday the 14th. The swell kicks up to 3ft from the WNW, and the period stretches to 11 seconds – that’s proper groundswell. The energy is moderate (190) and the wind is dead calm, glassy. Still, it’s only 3ft, so it’s just “surfable.” The afternoon sees the energy rise a bit (201) but the wind goes cross-onshore, messing it up.
Saturday the 15th is a tease. The swell hits 4ft, but it’s a short-period 7-second windswell. The energy is moderate (186) but that onshore wind from the WNW just ruins it for paddle surfing. Honestly, this looks better for the kite crew.
Now, circle Tuesday the 18th of August on your calendar. That’s the one. The morning brings a 4ft swell from the WNW with an 8-second period, and the energy is strong (204). The key is the wind: a clean 6 mph offshore from the east. That’s the best wind we’ll see all forecast. The wave height is good for intermediates, and the offshore wind will make it clean and fun. The afternoon is worse, with the wind shifting cross.
After that, it fades. Wednesday the 19th has rain showers, Thursday the 20th is another cross-onshore mess, and Friday the 21st morning returns to a glassy 3ft WNW swell (158 energy) – surfable, but nothing to write home about. The final weekend of the 22nd gets some size, 5ft to 5ft, but the wind is onshore or cross-onshore, and the energy is strong (531) – lots of power, but it’ll be blown out.
So, in short: it’s a slow two weeks. The Tuesday morning of the 18th is your best chance for a clean session. The rest is mostly a waiting game.
Rusty.

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.
