The Lowdown
Alright, let’s get into it. Rusty here, looking over the next couple of weeks for Lacanau-Ocean.
Saturday morning, August 1st, is a flat start. The swell is tiny, only 2ft from the northwest, with a short period of 6 seconds and weak energy (44). The wind is a light cross-shore from the north, but the waves just aren’t there. It’s the same story through the weekend – small, messy, and not worth paddling out for. The whole first week is a bust, with the swell barely reaching 3ft and the wind often cross-on or onshore, chopping up what little bump there is. The combined energy stays in the weak range (under 100), so you’re not missing a thing.
The first real glimmer of hope comes on the morning of Friday, August 7th. The wind shifts to a light cross-offshore from the southeast, cleaning things up nicely. The swell is still small at 2ft from the northwest, but it’s surfable and the conditions are clean. It’s a light breeze, so the surface will be smooth. The energy is still weak (43), but for a quiet session on a longboard, it’s your best bet in days.
The following week offers a few more windows. On the morning of Tuesday, August 11th, we get light offshore winds from the east-northeast (ENE) and a clean 3ft swell from the west-northwest. The period is 8 seconds, so it’s a small, short-period wave, but with the glassy conditions, it’ll be fun. The energy is moderate (121). The next morning, Wednesday, August 12th, is the standout. The wind is a light cross-offshore from the east-northeast again, the swell is 3ft from the west-northwest, and the period pushes up to 10 seconds, giving the waves a bit more shape and push. The combined energy is moderate (185), and it’s clean. This is the best on offer for the whole forecast – a small but clean, punchy morning.
After that, the swell drops back down. By the morning of Sunday, August 16th, the swell is barely 1ft from the west, with a short period of 7 seconds and very weak energy (15). The wind is a moderate cross-offshore from the northeast, keeping it clean, but there’s simply no wave to ride.
Overall, it’s a lean spell. The first week is a write-off. The best windows are the morning of the 7th, 11th, and especially the 12th of August. The water temp is about average for the time of year, so no need for a thick suit. Keep your expectations low, and you might snag a few clean ones.
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.
