The Lowdown

G’day, Rusty here, and I’ve got the lowdown on Lacanau-Ocean for the next couple of weeks. It’s a bit of a mixed bag, so let’s get into it.

Right off the bat, Thursday morning, the 13th, is your real standout. The water’s sitting at 76°F—that’s about 5°F above the norm, so it’s much warmer than usual for this time of year, which is a nice bonus. You’ve got a clean 2ft swell from the west with a 10-second period, but the wind is glassy and from the southwest at just 3 mph. The combined energy is weak (93), but for a small wave session, it’s going to be as clean as a whistle. The break is consistent, exposed to the west, and the optimum swell direction matches up perfectly. This is the pick of the forecast.

The rest of the 13th and through the 14th, 15th, 16th, 17th, 18th, and 19th is pretty ordinary. Onshore and cross-onshore winds, choppy conditions, and small swell keep the scores low. Thursday afternoon the 13th goes cross-on from the northwest at 9 mph, and the swell drops to 2ft. Friday morning the 14th has a little bump to 3ft but it’s onshore, and the energy is only moderate (128). Saturday morning the 15th offers a slightly bigger 4ft from the WNW, but the period is short at 8 seconds and the wind is cross-on. It’s all poor surf conditions until the 20th, so there’s a solid week of flat, messy days.

Now, Thursday morning the 20th sees a change. The swell jumps to 6ft from the WNW with a 12-second period, and the combined energy is strong (763). The wind is cross-shore from the NNW at 9 mph, and the conditions are described as marginal. The period is long enough to give some shape, but it’s a beach break, so that long period might make it a bit straight. This is for the more experienced crowd—6ft is getting up there, and it’s not for beginners. The afternoon of the 20th is cross-on and choppy again, so don’t bother.

The 21st through the 22nd are all onshore or cross-on, with the swell dropping from 5ft to 2ft. Not worth the paddle. Sunday morning the 23rd finally gives a brief window: offshore wind from the east at 6 mph, with a 2ft swell from the NW. The combined energy is weak (53), but it’s clean. It’s just small, so you’ll be on a longboard.

Monday morning the 24th is glassy again with a 1ft west swell, but it’s tiny. Then Tuesday afternoon the 25th, look out—the swell spikes to 10ft from the west with a 9-second period and a massive combined energy of 1337. That’s a lot of power, and the wind is onshore from the west at 12 mph. The file says it’s too big for this break, and honestly, that’s a beast for experts only. For most of us, it’s a no-go.

The final days from the 26th to the 28th are all onshore or cross-on, with swell between 3ft and 4ft, and poor conditions. Nothing to get excited about.

So, to wrap it up: Thursday morning, 13th August, is your golden ticket—clean, glassy, and warm. After that, the 20th morning has some size and energy, but it’s a bit messy. The rest is a write-off until maybe the 23rd morning for a small, clean session. Don’t bother with the 25th unless you’re a pro looking for a beating.

Stay stoked, 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.
