The Lowdown

Alright, Rusty here. Let me break down what’s cooking for the next couple of weeks at Lacanau Ocean.

We’ve got a bit of a slow start, but once the windows line up, this place can turn on. The water is sitting at a toasty 73°, which is way warmer than usual for this time of year – almost two degrees above normal. That’s a nice bonus for the early sessions.

Monday morning (14th) is the first real shout. Clean, glassy conditions with a 3ft swell from the WNW, a period of 11 seconds – that’s proper groundswell energy. Combined energy is 214 (moderate), and with that glassy wind, the waves should be clean and workable for intermediates. The optimum direction is from the west, so the WNW swell is a good match. Crowds are possible here, so keep an eye out.

From Monday afternoon right through to Thursday morning (17th), it turns messy – cross-shore and cross-onshore winds, small chop, and the sets just don’t hold. Wednesday morning (16th) actually has some size, 5ft, and energy jumps to 310 (moderate), but the period is short at 8 seconds and the wind is cross. That’s a pass for paddle surfing – looks more interesting for kites.

Thursday afternoon (17th) through Sunday morning (20th) is where it gets interesting. Friday morning (18th) is a real gem – clean, cross-offshore winds with 4ft from the WNW, 9-second period, combined energy 282 (moderate). Not huge, but clean and fun for intermediates.

Saturday morning (19th) is the standout. Glassy, 5ft from the WNW with a 13-second period (long period groundswell). Combined energy hits 781 (strong). That’s a serious amount of push. A long-period swell like this can break a bit straight on the beach, but with glassy conditions and that much energy, it’s going to be a morning to remember for intermediate to advanced surfers. Get on it early.

Sunday morning (20th) stays clean with cross-offshore winds and 4ft from the WNW, energy 317 (moderate). A solid follow-up.

Monday morning (21st) is another banger. 5ft from the WNW, very long 14-second period, combined energy a whopping 904 (very strong). Clean cross-offshore winds. This is proper groundswell, and for a beach break, look for the banks that can handle that period. Advanced surfers will be on it.

After that, the week tails off. Tuesday (22nd) still has some clean morning waves at 3ft and 12-second period, energy 284 (moderate), but the afternoons get gusty. Wednesday (23rd) and Thursday (24th) are small and windy – under 3ft, not worth getting wet.

Friday (25th) and Saturday (26th) bring a new pulse: 4ft to 4ft from the W and WNW, with very long periods of 14 and 15 seconds. Energy is 574 to 742 (strong). The winds are clean and cross-offshore, but these are still long-period swells, better at a reef or point. The forecast is less certain this far out, so it’s promising but not locked in.

Sunday (27th) and Monday (28th) drop back to small or blown-out. Monday afternoon (28th) gets ugly – 8ft from the WNW with 25 mph onshore wind. That’s a closed-out mess, only for experts who don’t mind a beating.

Then Tuesday (29th) fades out with rain and onshore wind. A blank end to the run.

Bottom line: Saturday morning (19th) and Monday morning (21st) are your best shots. Saturday is glassy and solid; Monday is powerful and clean. Don’t sleep on that Saturday glass-off.

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.

Lacanau Ocean is 38 km (24 miles) from Arcachon. If you plan a holiday in Gironde, look for hotels and other accommodation in Arcachon. Arcachon has rooms for a wide range of budgets as well as car hire and transport links.
