The Lowdown
Hey crew, Rusty here. Let’s break down what’s happening at Lacanau Ocean over the next couple of weeks. I’ll be blunt – it’s mostly a flat, messy picture. The first week is full of onshore slop and tiny waves.
Starting Wednesday the 22nd, it’s small and bumpy. The water is unseasonably warm at 77°F (about 7°F warmer than average), so the water feels nice, but the surf doesn’t.
There’s a little pulse of energy on Saturday the 25th, with the swell up to 4ft from the WSW, but the wind is onshore and the period is short. The combined energy is weak (156). Sunday the 26th sees a bit more height at 5-5ft from the WNW, but it’s still onshore and short period. Not worth getting wet for.
The first real chance for a clean wave comes on the morning of Tuesday the 28th. The swell drops to 3ft from the WNW, but the wind goes glassy. That is a huge positive – the waves will be clean. The period stretches to 9 seconds, giving them a bit of push. The energy is moderate (154). It’s surfable, but it’s nothing to write home about. Wednesday the 29th morning is a similar setup with glassy conditions and 2ft waves.
Looking into the second week, there’s no major stand-out swell. Your best windows are a few mornings with light or glassy wind: Sunday the 2nd of August morning (3ft, glassy), Monday the 3rd of August morning (3ft, glassy), and Tuesday the 4th of August morning (4ft, glassy). The morning of Wednesday the 5th of August also looks glassy with 3ft waves. These will be clean but small sessions – good for a log, not much else. The combined energy sits in the moderate range (100-180).
It’s a dry spell, for sure. Keep the board waxed and hopes up – forecasts can flip. Those glassy mornings are your only real shot.
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.
