The Lowdown
Alright, Rusty here. Let’s take a look at what’s cooking in the water up at Lacanau Ocean.
Right now, things are pretty flat and messy. Wednesday the 2nd is a write-off with a cross-on wind messing up a tiny 3ft WNW swell. Thursday the 3rd and Friday the 4th are still small, but Friday morning shows a bit of a glimmer with clean conditions and a 3ft swell under a light cross-off breeze, though the energy is weak (76).
The first real glimmer of hope comes on Saturday the 5th. Saturday morning is clean with a light cross-off breeze, and the swell bumps up to 3ft from the WNW with a decent 12-second period. The combined energy jumps to 250 (moderate). That’s a fun little window for a longboard or a fish. Saturday afternoon gets bigger but messy with a strong cross-shore wind, so stick to the morning.
Sunday the 6th morning is a standout. We’ve got a clean 3ft groundswell from the WNW, period at 11 seconds, and an offshore wind out of the ENE. The water’s sitting at 74°F, which is a touch warmer than normal for this time of year. This is the best session of the first week – clean, organised, and just enough juice.
The middle of the week (Monday 7th through Thursday 10th) drops right back off. Onshore winds, choppy, small swell. A proper lull.
Now, look ahead to the second week, and there are two real standouts to circle on your calendar. Saturday the 12th morning is pure glass. Wind is dead calm out of the SSE, waves at 4ft from the WNW, period an average 8 seconds, but it’s clean and user-friendly. Combined energy is moderate (222).
But the absolute pick of the entire 16-day window is Sunday the 13th morning. Calm, glassy conditions with zero wind. Swell sits at 5ft from the WNW, with a long 12-second period, pumping the combined energy up to a strong 677. That’s proper. The waves will have shape and power. At 5ft, it’s solid for intermediates and will be too much for beginners, but for the crew who know what they’re doing, this is the morning to be out. Crowds are *sometimes* an issue here, so get there early.
Monday the 14th and Tuesday the 15th mornings are also clean and rideable with 4ft swell, but nothing tops that Sunday.
Overall, the surf starts slow, but the weekend of the 12th and 13th delivers the goods. Lock in Sunday the 13th morning – that’s the one.
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.
