The Lowdown

G'day, Rusty here. Look, I've got to be straight with you – the next couple of weeks are looking pretty grim for a proper surf at Lacanau Ocean. We've got a long stretch of poor conditions ahead, so don't get your hopes up too high.

The whole 16-day window is a bit of a wasteland, to be honest. For the first week, from Monday the 3rd right through to the end of the next weekend, it's mostly small, weak, and messy. The swell is tiny, never getting above 4 ft, and the wind is nearly always cross-on or onshore, chopping everything up. The combined swell energy is pathetic, barely scraping into double digits for most of that time, with the highest reading being a meagre 111 (moderate) on Thursday the 6th morning, but that's with a short 8-second period and cross-shore wind. Not worth paddling out for.

The water is running at 75°, which is a solid 4° warmer than usual for this time of year – noticeably warm, but it won't save the surf.

The first real glimmer of anything decent comes on Friday the 7th in the morning. We've got a light NE breeze, making it cross-offshore and clean. The swell is tiny, only 2 ft from the NW with a 6-second period, and the energy is a weak 50. It's surfable, but very ordinary. If you're desperate, you could get a few little ones, but don't expect much.

After that, it's back to the same old story: small, onshore, and choppy. The morning of Saturday the 8th has an offshore easterly at 3 mph, but the swell is just 2 ft from the NW with a 5-second period and a combined energy of only 20. It's clean, but there's no power behind it.

The second week doesn't offer any redemption. From the 10th onwards, it's all small, short-period, and wind-affected. The morning of Saturday the 15th sees a bump in swell to 4 ft from the NW with a 6-second period, and combined energy hits 128 (moderate), but it's cross-on from the SSW at 9 mph, making it choppy. Not a standout.

The 18th of August Tuesday morning has some energy at 103 (moderate) with a 7-second period and 3 ft swell from the NW, but it's cross-on from the SW at 12 mph, so it's all chop. The afternoon of the same day is a write-off: 22 mph onshore winds from the WSW.

Honestly, if you're a kite surfer, the strong onshore winds on the 18th might look interesting, but for us paddle surfers, there's just nothing to get excited about. The only half-decent window is Friday the 7th morning, and even that's a stretch. Hang tight, mate. It's a blank run, but it won't stay this way forever.

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.
