The Lowdown

Alright, let’s have a look at what’s cooking for the next couple of weeks here at Lacanau Ocean.

The overall picture is pretty quiet to start. We’ve got a small window of clean, rideable waves on Tuesday the 1st of September, but then the energy drops right off and conditions get messy for a good stretch. There’s a real gap mid-week, with a few days of almost nothing worthwhile. It’s not until the weekend that things start to look interesting again.

The standout by far is the first session: Tuesday morning. We’ve got a clean 5ft swell from the WNW with a 10-second period, and the wind is a light cross-off breeze from the NE. The water temp is about average for this time of year, so no need to dig out the winter suit. The combined energy is moderate (356), so there’s enough push for a fun, punchy wave. It’s a consistent, exposed beach break that handles the west swell well, and with the clean conditions, this is the session to target. The only thing to mention is that crowds are possible here, so get in early.

After that, it’s a bit of a flat spell. The swell drops to under 3ft, the wind is messy, and the energy readings are weak (86, 57, 25). From Wednesday the 2nd through to Friday the 4th, it’s really not worth paddling out unless you’re desperate for a splash.

Things start to improve on the 5th of September: Saturday morning shows a clean 3ft swell from the WNW with a 10-second period, and the NE wind is under 5 km/h – almost glassy. That’s a solid session, with moderate energy (217). It’s not huge, but it’ll be clean and fun on the beach break.

The following week is a mixed bag. There’s a bit of a pulse on the 10th of September (Thursday morning) with a 4ft WNW swell, but the wind is cross-on from the NW, which chops it up. The energy is solid (307), but those onshore winds spoil it. The best of the second week actually looks like the 12th of September: Saturday morning with a clean 1ft offshores from the ENE. Not much size, but it’ll be clean and glassy. The 14th of September (Monday morning) gives us a glassy 2ft wave too, but again, it’s small.

For the last few days, the 15th and 16th of September, we get a bit of a bump in size on the 15th (5ft) but it’s cross-on and choppy, so that’s not your friend. The 16th is small and messy.

Realistically, if you’re after the best waves, it’s Tuesday the 1st of September first thing. That’s the clear winner. Saturday the 5th morning is a good backup. The rest of the 16 days is mostly small, windy, or both.

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.
