The Lowdown
Alright, Rusty here, breaking down the next couple of weeks at Lacanau Ocean.
To be straight with you, the first ten days or so are a flat spell. The swell is tiny and the wind just won't play nice. You're looking at a big gap of poor to ordinary surf.
The one day that stands out is the morning of Saturday, August 8th. That's the call. There'll be a 3ft swell from the West, and it's going to be clean with an offshore breeze out of the East. The combined wave energy is moderate at 204, and that offshore wind means smooth, lined-up waves. This is easily your best bet.
The water temp is about 70°, which is average for this time of year, so nothing unusual there.
For the rest of the period, there's a couple of early morning windows that might scratch an itch if you're keen. Sunday, August 2nd, has a glassy, flat 2ft swell, but it's short period so sluggish. Friday morning, August 7th, picks up to 5ft from the West with decent energy (283), but the cross-onshore wind will chop it up. And Thursday morning, August 13th, has a clean wind, but the swell is only 2ft.
It's a long, quiet stretch with one proper highlight: the morning of August 8th. Save your energy for that one.
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.
