The Lowdown
Alright folks, Rusty here. Let’s get stuck into the outlook for Le Kerou.
Right off the bat, I gotta be straight with you – the next few days are a proper write-off. The surf is tiny or blown out by cross-onshore winds, and the quality is just poor. We’re looking at a dry spell right through until the morning of Thursday the 22nd of August. That’s nearly a full week of waiting for something worthwhile.
The first real glimmer of hope arrives on the morning of Thursday, 22nd August. We’ve got a 2ft swell rolling in from the west, with a period of 8 seconds. The kicker here is the wind – it’s a gentle offshore from the northeast, keeping things clean. The combined energy is weak, at only 71, so don’t expect much power, but for a beginner-friendly break like Le Kerou, those small, clean waves are a decent morning session. The water temperature is a touch warmer than normal at 68°F.
After that, the surf drops right back down again. The next few days see tiny, weak, and inconsistent waves, with the wind swinging onshore again. It’s a tough stretch.
We’ve got a period of more promising swell energy building from the 25th of August, but the wind is a persistent cross-onshore, leaving the surf choppy and poor. There’s a bit of a swell on Tuesday the 25th, hitting 4ft to 5ft, but that southerly wind just wrecks it.
The standout moment in this whole 16-day window shapes up for the morning of Thursday, 29th August. Now, this is a long way out, so treat it as a promising but not locked-in call. The forecast shows a 4ft swell from the southwest, period of 8 seconds. But the real magic is the wind: glassy. Zero wind. That’s going to make Le Kerou as clean as a whistle. The combined energy is moderate at 189. It’s not a big swell, but with that glassy surface, it’ll be the best we’ve seen in this whole run. For a beginner-friendly spot, this is your window.
After that, the swell fades away into the start of September, with small, weak waves and mostly cross-onshore winds returning. The 2nd of September morning shows a pulse of 3ft west swell with clean conditions, but energy is still only moderate.
So, to wrap it up: the best and only real standout is the morning of Thursday, 29th August. Mark it in your calendar. Everything else is a waiting game.
Rusty.
