The Lowdown
Alright, Rusty here, taking a look at what's cookin' for the next couple weeks. It's gonna be a slow grind to start, but there's a real good pulse comin' if you got the patience.
Water's sittin' at a balmy 74°F – that's about 4°F warmer than normal for this time of year, feels like a summer bathtub. Today and the next few days are flat and messy. Thursday 3rd September afternoon has some small lines, but with a cross-shore wind from the NNW at 9 mph, swell only 3 ft from the WNW at 8 seconds, and low energy (66). Not worth wetting a suit.
Friday 4th September morning starts with a glass-off! Wind is from the NNE at 3 mph, dead calm, but the waves are tiny at 3 ft with an 8-second period. It's surfable, but just barely. The afternoon gets chopped out.
Now, Saturday 5th September morning is where we get our first real window. Clean conditions with a light cross-offshore breeze from the NE at 3 mph, swell picks up to 3 ft from the WNW with a 9-second period, and energy jumps to moderate (288). Lacanau Ocean will have fun, clean little peaks. This is the pick of the first week for a small-wave session. The afternoon gets bigger to 4 ft, and the period stretches to a tasty 13 seconds (that's real groundswell) with strong energy (543), but the wind swings cross from the N at 12 mph, making it a bumpy mess. What a shame.
Sunday 6th September morning is another good call. Offshore wind from the E at 9 mph (clean!), swell is 3 ft from the WNW with an 11-second period, and energy is moderate (265). Get out early for clean lines. The afternoon turns onshore and ugly.
Monday 7th through Saturday 12th is a rough stretch. Onshore breezes, chop, and small swell rule. Saturday 12th September morning has a light offshore wind from the E at 6 mph, but the swell is only 3 ft with low energy (119). Barely surfable.
Circle Sunday 13th September morning in your calendar. That's the real gem. Wind is a light offshore from the ENE at 6 mph, creating clean glass. Swell hits 4 ft from the WNW with a very long 14-second period. Energy is strong at (604). That's a proper groundswell with real push. Lacanau Ocean will have clean, powerful waves. This is the session to save for. Afternoon gets cross-onshore again, so it's a morning-only deal.
The second week is mostly a bore. Monday 14th and Tuesday 15th offer small, average waves. Wednesday 16th September morning has a glass-off again: wind from the E at 3 mph, dead calm, but the swell is only 2 ft. Clean but tiny. The rest of the week fades into onshore slop.
Best bets: Saturday 5th September morning for clean small waves, and the absolute standout is Sunday 13th September morning for a proper groundswell with clean conditions. Don't sleep on 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.
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.
