The Lowdown

Alright, Rusty here, checkin' in from the coast. It's been a bit of a flat, choppy mess lately, but don't you worry, there's a glimmer on the horizon. Let's break it down for you.

The water is sitting at a surprisingly warm 78°, which is a solid 6° warmer than usual for this time of year. Feels more like a tropical swim than an Atlantic session, so you'll be shedding the wetsuit or at least going for a spring suit.

First up, things are looking pretty grim from now through the rest of the week. We've got a solid week of onshore, cross-onshore, and generally messy winds. Thursday and Friday are a write-off, with small, choppy waves. Saturday morning (22nd August) offers a tiny bit of hope with a clean 3ft swell from the WNW and a light offshore breeze from the East. The energy is weak (147), but it's the only clean window in the near term. The swell period is a short 9 seconds, so don't expect much push.

Then we hit a major flat spell. From Sunday morning (23rd August) all the way through to Tuesday afternoon (25th August), the swell drops to almost nothing. The energy readings are in the teens and low twenties. It's a total blank. On Tuesday afternoon, a pulse of 5ft shows up, but it's accompanied by a strong onshore wind, making it a total mess.

The real standout is still a week away, but it's worth circling on the calendar. Thursday morning, the 27th of August, is looking like the pick of the whole forecast. We've got a clean 6ft swell from the West, with a light cross-offshore breeze from the SSE. The combined energy is a solid 443, which is a proper moderate push. The period is only 8 seconds, so it's wind swell, but with that light wind, it'll be clean and fun. The morning session is the one to aim for. The afternoon gets a bit too big for Lacanau Ocean, with a 10ft swell and a cross-onshore wind. That's expert territory and a bit messy.

The Friday morning (28th August) after that has a 7ft swell from the West with a light onshore wind, which is marginal. The rest of the second week fades out into small, choppy, or onshore conditions again. The 1st of September has a big 7ft swell from the West, but it's clobbered by a strong cross-onshore wind, making it a kite-surfing day more than a paddle-out.

So, to sum it up: the next week is mostly a washout. Save your energy for Thursday morning, the 27th of August. It's the one session that's worth the paddle. The long-range stuff is promising on paper, but with the wind being so fickle, don't hold your breath.

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.
