The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the next fortnight at Lacanau Ocean is a real mixed bag, and honestly, it’s a tough run for most of it. We’ve got a long stretch of poor conditions, but there are a couple of windows that might just get your heart rate up.

We start off this Friday, the 24th of July, with next to nothing. Tiny 0.7 ft swell from the west with a 9-second period, and while the morning wind is a clean cross-off from the ENE, the energy is just pathetic (8). It’s not worth paddling out for. That pretty much sets the tone for the next several days. Through Saturday and Sunday, we get a bit of height – 5 ft on Saturday morning – but the period is a short, bumpy 6 seconds, and the wind is onshore or cross-onshore, making a mess of things. The wave energy creeps up to moderate levels (129–183), but the quality is poor. Monday is no better, with cross and cross-on winds chopping up a 4 ft to 4 ft NW swell. There’s a brief glimmer on Tuesday morning, the 28th – the wind goes glassy, dead calm, with a 3 ft WNW swell at a decent 10-second period. The water is a warm 74°, and it’s a touch warmer than normal for this time of year, which is nice. The waves are surfable but very ordinary, and the energy is moderate (171). It’s the best we’ve seen, but it’s hardly a standout. Crowds are possible here, as it’s a consistent spot, but with the conditions, it might be quiet.

Moving into the second week, the pattern doesn’t improve much. We have a few more mornings with glassy or light wind, like the 31st of July, but the swell drops back to 2 ft with a short 8-second period and weak energy (42). Not worth a wet suit. Then, on the 1st of August, the swell picks up dramatically – a solid 5 ft from the west with a very long 14-second period, and the energy jumps to a strong 453 in the morning and 681 in the afternoon. This is the real standout of the whole forecast. The problem? The wind is onshore from the west and WNW, making it a marginal forecast with questionable tide conditions. The period is long (14 seconds), which means it’ll be a proper groundswell, but at a beach break like Lacanau, it might break too straight and be tricky. Given the size (5 ft) and the onshore wind, it’s really only for the experienced crew. The afternoon of the 1st sees 5 ft waves with a 12-second period, but the wind remains onshore. This is the best chance we’ve got, but it’s far from perfect.

After that, the whole second week slides back into a monotonous grind of 3 ft to 4 ft WNW swell, with 9 to 10-second periods, and cross-onshore winds from the NW or W. The energy stays moderate (166–286), but it’s all poor surf conditions. The wind never really cleans up, and the period is too short to get excited about. The last few days, from the 5th to the 8th of August, are just more of the same – rain showers, moderate wind, and choppy, ordinary waves. The swell drops back to 2 ft on the 8th afternoon, with weak energy (52), and that’s it.

So, to sum it up: the first week is a write-off, with a small glassy window on Tuesday morning that’s barely surfable. The real highlight is the 1st of August, with a strong, long-period groundswell, but you’ll have to deal with onshore wind. It’s promising but less certain that far out. For the rest of the time, we’re looking at a long gap of poor surf – it’s just not our month. Keep an eye on the forecasts, though; it tends not to stay this poor for long.

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.
