The Lowdown
Alright, Rusty here, lookin’ at the surf ahead for Lacanau. Gotta be straight with you, the next couple of weeks are lookin’ pretty flat and sad for us. The swell window just ain’t openin’ up. We’re in for a long stretch of tiny, weak waves and mostly ordinary conditions. It’s gonna be a test of patience.
First up, Monday morning, August 10th. We’ve got a tiny bit of life with a 2ft NW windswell. The energy is real weak, only 58. The wind is dead calm though – glassy as a mirror. You could probably find a ripple to float on, but it’s barely surfable. By the afternoon, the wind swings NW at 9 mph, turnin’ it onshore and messy. That’s that for Monday.
Tuesday, the 11th, is even smaller. Droppin’ to 1ft with a short, weak period of 8 seconds. Morning wind is light offshore from the WSW, but the swell’s just too pathetic. Not worth wettin’ a suit.
Wednesday morning, the 12th, is glassy again with a 1.0ft W swell, but the period jumps to 11 seconds. That’s a longer-period groundswell, which is promising in theory, but the size is non-existent. The energy is still just 48. You’d be paddling for nothing.
We roll into Thursday and Friday, the 13th and 14th, and the swell tries to bump up a bit – 2ft to 3ft from the W – but the energy is still in the low triple digits at best (89-132). The problem is the wind. It’s onshore or cross-onshore from the WSW or NW every session, wreckin’ any chance of a clean face. It’s just poor.
The weekend of the 15th-16th sees the biggest swell of this whole run, but it’s still only 4ft on Saturday morning. The wind is a messy cross-onshore from the SW, and the period is a short 8 seconds. It’s poor, weak, and choppy. Not your weekend warrior conditions.
Monday the 17th gives us a small window of clean surf in the morning. The swell is 3ft from the NW with a 7-second period, and we get a light NE cross-offshore breeze. It’ll be clean, but the waves will be weak and fat. It’s a “surfable but very ordinary” kinda morning.
After that, it’s more of the same through the end of the week. We see a bit more size on Wednesday afternoon the 19th, with a 4ft NW swell, but the period is a poor 7 seconds and the wind is a messy cross-shore. It’ll be a junky closeout.
The best window of the whole outlook? Honestly, it’s probably the early morning of Wednesday, August 19th. We’ve got a clean, offshore wind from the East at just 3 mph. The swell is a small 2ft from the WNW with an 8-second period. The combined energy is only 86, so it’s weak, but it’s the cleanest and most ridable window we’re gonna get. It’s a session for the longboard or a foamie, just to get wet. Don’t expect any barrels.
The rest of the run into the 25th is just flat, windy, or both. There’s no standout surf at all. This is a blank run for the area – sometimes it just happens. The forecasts can change, so don’t lose hope, but for now, leave the boards in the car.
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.
Lacanau Ocean is 38 km (24 miles) from Arcachon. If you plan a holiday in Gironde, look for hotels and other accommodation in Arcachon. Arcachon has rooms for a wide range of budgets as well as car hire and transport links.
