The Lowdown
Alright, Rusty here, and I’m staring at the charts for Le Kerou. It’s a pretty bleak outlook for the next 16 days, if I'm being honest. This break usually needs a good W swell and some luck with the wind, but the forecast window is looking more like a time to wax the longboard for a flat spell.
We kick things off on Saturday the 29th of August with a 8ft SW swell rolling in. Sounds decent, but the wind is a fresh 22 mph cross-onshore, making it a lumpy, choppy mess. The combined energy is a moderate 860. That’s not surfable. That pattern holds. We spend the next two weeks fighting onshore winds. There's a window on the morning of Tuesday the 1st of September where the wind goes glassy for a second, but the swell has dropped to a weak 3ft from the W with a combined energy of only 169. It’s surfable, but very ordinary. You’d be scratching for anything rideable.
From there, it just gets smaller. The mornings of the 4th and 5th of September see a bit of a pulse, with a 4ft and 4ft W swell carrying a bit of period (12 seconds and 11 seconds), producing moderate energy (497 and 329). But the wind is cross-on or cross-shore, so it’s not clean. Not worth the paddle out.
Then we have a massive gap of poor conditions until the real standout. The only time worth marking your calendar is Friday the 11th of September. Friday morning is a solid call. We’ve got clean conditions with a light cross-offshore breeze from the east at 9 mph. The swell is a 4ft groundswell from the WSW with a very long 14-second period. The combined energy (748) is strong, meaning it will carry some punch. That long period means it’s going to reel nicely, so if you’re surfing somewhere with a defined peak, it’ll be your best bet. The water temp is sitting at a normal 66° for this time of year, so no worries about a thermocline.
By Friday afternoon, it’s a bit bigger at 5ft and the energy jumps to a very powerful 1105, but you’ve got a light cross-on wind, so the surface won’t be as clean as the morning session. Saturday the 12th still has some 4ft swell in the water, but the wind isn't cooperating again.
Overall, if you’re an absolute beginner, the mornings up to the 5th or the 12th are too small to be dangerous. For everyone else, don’t bother until that Friday the 11th morning session. That’s the only true standout here.
Rusty, signing off.

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 Le Kerou 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.
