The Lowdown

Alright folks, Rusty here. Let's have a look at what's coming down the line for us at Lacanau Ocean.

We’re in for a bit of a mixed bag over the next couple of weeks. The first few days are pretty average, but stick with it because there’s some real magic brewing way out there in the forecast. The good stuff is going to come in waves, with a few clean windows to aim for.

The week kicks off on Saturday the 12th with some tiny, weak swell. The morning is glassy but with only 2ft of swell and very low energy (72), it’s not really worth getting wet. The wind turns nasty in the afternoon and messes it up completely.

Now, Sunday the 13th is where we start to see some life. The morning is looking clean with glassy conditions and a nice long-period groundswell filling in. Swell bumps up to 4ft from the WNW with a solid 13-second period, pushing the energy up to a moderate 367. This is going to be fun on the sets, with good shape. The wind stays light and offshore out of the NE, so it’ll be clean. The afternoon goes cross-on and choppy, so get your session in early.

Monday the 14th is another morning option. The swell drops a touch to 3ft but the period stays long at 11 seconds, keeping 214 energy in the water. Glassy conditions again with a light Easterly breeze. It’s not a classic, but it’s surfable and clean.

After that, we hit a dry spell. From Tuesday the 15th all the way through to Saturday the 19th, the wind is all over the place – cross, onshore, and generally messy. The swell sticks around but the quality is just poor. Best to leave the board in the car for that entire stretch.

Things start to look promising again on the morning of Sunday the 20th. We get a clean, cross-off breeze from the NNE and some waist-high waves. It’s not huge, but it’ll be clean and fun. Monday the 21st morning is even better with a clean 3ft from the WNW and good energy (238). Then Tuesday the 22nd and Wednesday the 23rd mornings are absolute winners. Light offshore winds from the ENE are forecast, with clean 3ft to 4ft surf and a fantastic 11-second period. The energy reads solidly in the moderate range (239 and 319). These are the sessions to circle on your calendar for a proper dawny.

Now, hold onto your leggies, because the real standout is coming up on Friday the 25th. I’m getting excited just looking at this. The morning is glassy, like a lake, with a proper pulse of WNW groundswell delivering 6ft at a very long 14-second period. The wave energy is sitting at a massive 1461, which is some serious power. This is excellent surf, but with that size and power it’s definitely one for experienced surfers only. The swell direction (WNW) matches the break’s optimum perfectly, so expect some nice, lined-up walls. The afternoon gets a bit messy with the cross-on wind, but the morning will be a session to remember.

Saturday the 26th morning is still looking good for the more advanced crew, with 5ft of clean, lined-up swell, and a quick look at Sunday the 27th shows a clean, offshore morning as the swell fades.

So to boil it down, your absolute best bets are the clean mornings of Sunday 13th, Tuesday 22nd, and Wednesday 23rd. But the jewel in the crown is the Friday 25th (25 September) morning session. That’s the one to take a day off work for. Just remember, when it’s that good and that big, the crowds at Lacanau are sometimes a factor, so get out there early.

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.
