The Lowdown
Alright, let's get into it, folks. Rusty here.
Alright, listen up. It’s gonna be a bit of a patience game for the next week or so. The surf is really struggling to get its act together, with a lot of small, weak, and messy conditions. The wind is just all over the place, and the swell is mostly tiny and short-period. We’re looking at a lot of days where it’s just not worth paddling out.
The first real glimmer of hope doesn't come around until Monday the 28th of July. That morning at Lacanau Ocean, we’ll see the wind drop to almost nothing, turning glassy. It’s a small swell, only 3ft but it’s coming from the WNW with a period of 9 seconds, which is a proper groundswell. The energy is moderate (141), and the clean conditions will make it feel better than it looks. It’s not going to be pumping, but for a quiet session, it’s the best we’ve got early on.
Then we get a few more days of the same old story—small, choppy, and onshore. The swell tries to pick up a bit on the 30th of July, with a 4ft NW swell, but the wind is all wrong, making it messy.
Now, the real standout is a long way off, but it’s a big one. Mark your calendars for the morning of Sunday, August 2nd. Lacanau Ocean is looking at a massive 10ft swell from the WNW, with a 10-second period. The energy is absolutely enormous (2755). The wind is set to be light and offshore from the NE, which is perfect. The waves are going to be clean and powerful. However, this is no joke. This is a serious, expert-level swell. At over 8ft, it’s for experienced surfers only. Beginners, stay well clear of the water that day. It’s the one true standout of the entire 16-day window, but it’s a long-range call, so the details could shift.
The Tuesday morning after that, the 4th of August, there’s another chance for a glassy session with a very small 3ft swell, but it’s a far cry from the Sunday action.
Stay patient, and keep an eye on that big Sunday swell.
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.
