The Lowdown

G'day, I'm Rusty. Let's have a look at what's shaping up for Lacanau Ocean over the next couple of weeks.

We've got a bit of a mixed bag here. The forecast opens with a small, weak swell on Saturday the 5th, but the wind is a messy cross-shore and the whole setup is marginal. Not one to get excited about. The real story starts to build from Sunday morning, and there are a couple of windows that look worth paddling out for.

Sunday the 6th morning is where we start. The swell is a clean 4ft from the WNW with a decent 11-second period, giving the waves some shape. The wind is light from the south, swinging cross-offshore, which will keep the surface clean. The combined swell energy is moderate at 319. It's not a giant day, but for an intermediate, it's a solid, fun option. The water temp is 73°, which is 4° warmer than normal for this time of year, so it's notably warm – a nice bonus.

Tuesday the 8th morning is a real standout. We're looking at a 4ft swell from the WNW with an 11-second period, giving a moderate 358 combined energy. But the real winner here is the wind: absolutely glassy, dead calm from the NE. That means the surf will be clean as a whistle, no chop, just smooth lines. This is your best bet for the first week. It's a consistent, exposed beach break, so it handles swell well, and the crowd factor is only "sometimes," so you might get a few out but nothing crazy.

Wednesday the 9th morning sees a drop in size to 2ft, but the wind is a strong cross-offshore from the NNE at 22 mph. The combined energy is low at 136. It'll be clean, but the waves will be small and weak. Not worth the hassle.

The following week has a few flickers of hope. Monday the 14th morning brings back a 4ft WNW swell with an 11-second period and a light cross-offshore breeze from the NNE. That’s clean and has a moderate 223 combined energy. It's a decent, workable session for the intermediate crew.

The next real highlight pops up on Wednesday the 16th morning. We've got a 4ft swell from the WNW, but the period jumps to 12 seconds, which is a longer-period groundswell. Combined energy is a solid 347, and the wind is glassy from the NE. This will be another clean, lined-up morning. Just keep in mind that longer-period swells like this can sometimes make beach breaks a bit straight, but at 4ft, it should still be plenty of fun.

Thursday the 17th morning is also glassy with a 3ft WNW swell at 11 seconds. It's surfable and clean, but it's a smaller, more ordinary day.

Overall, the best on offer are definitely Tuesday the 8th morning and Wednesday the 16th morning. Both have that magic glassy wind and solid, surfable swell. Don't sleep on them.

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.
