The Lowdown
G'day, I'm Rusty.
Alright, let's have a look at what's on the cards for the next couple of weeks. The first week is pretty average to be honest, with a lot of onshore chop messing things up. But hold onto your board, because there's a real beauty lined up for the end of it that's got me a bit fired up. The water's sitting at a very unusual 73°, which is a good 4° warmer than you'd expect for this time of year – it's like having a warm bath out there. The main break to keep your eye on is Lacanau Ocean.
We kick off with Wednesday afternoon (9 September) and it's a bit of a washout. There's a cross-on wind from the NNW at 12 mph blowing over a 5ft WNW swell, period of 9 seconds. The combined energy is weak (342), and the surf is poor. You'd be better off staying in the pub.
Thursday morning (10 September) looks a bit better, with a clean 3ft swell from the WNW at 10 seconds. The big plus is that it's glassy, absolutely no wind. It's surfable, but the wave quality is still just ordinary. The afternoon sees the cross-on return and the size drop to 3ft, so it's back to poor.
Friday (11 September) has a tiny 2ft glassy morning, but there's very little push with an energy reading of only 55. It's a knee-high dribbler. The afternoon gets messy again with a cross-on breeze.
The whole of the next few days – Saturday, Sunday, and into Monday – are more of the same. You'll see small, chop-infested waves, with most afternoons getting blown out by a moderate NNW breeze. There's nothing worth calling a session here. Saturday morning (12 September) offers a clean 3ft with a light cross-off breeze, but it's gutless.
Then we get to Sunday morning (13 September). Now this is more like it. The wind is glassy from the NE and we’ve got a 4ft swell from the WNW with a period of 13 seconds – that's some proper groundswell. The combined energy jumps to a moderate 378. The report says to expect good surf conditions. This is the standout of the first week. Get out there early because the afternoon goes to shit with a 12 mph cross-on.
Monday morning (14 September) is another clean one with a light ENE cross-off breeze. The swell holds at 4ft, period 11 seconds, and the energy is a solid 256. The waves should be clean and fun, but again, the arvo's a mess.
We go through a few more days of choppy, onshore junk – a few morning windows with tiny, clean waves but nothing with any real grunt. It’s a bit of a quiet patch through to the end of the week.
Now, for the real standout. Mark your calendar for Monday morning, 21 September. I’m calling this the best on offer for the whole outlook. We’ve got a solid 8ft swell from the WNW, period of 10 seconds. The combined energy is a very strong 1040. The wind is a light N breeze at 6 mph, making it a clean cross-off. The report calls it excellent surf for experienced surfers. At 8ft, this is getting up there, so keep it for the crew who know what they're doing. The mornings will be the play; the afternoon gets a bit of cross-shore chop.
Tuesday (22 September) morning cleans up with a 5ft swell and 9-second period, and a glassy wind. The energy is a moderate 402, and conditions should be good. That's a solid follow-up day.
Through the rest of the second week, the mornings continue to look promising. Wednesday (23 September) and Thursday (24 September) both have clean, 4ft swells from the WNW with periods of 11 seconds and moderate energy readings in the 270 range. The mornings are the go, with light offshore or cross-off breezes. The afternoons will be choppy and poor, as usual for this spell.
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.
