The Lowdown
Alright, grab your boards – here’s the outlook for Le Kerou. Honestly, we’ve got a bit of a dry spell to work through before anything really clicks. The first week or so is pretty grim, with weak, short-period swell and onshore winds messing things up. Thursday morning the 10th kicks off with a tiny 2ft west swell and a light cross-onshore – really just not worth paddling out for, it’s poor. That theme holds through Friday, with the swell bumping up to 4ft but the wind stays cross-onshore and choppy. The combined energy is moderate (207 on Friday morning), but the conditions just aren’t there.
We finally get a window on Saturday morning the 12th. The swell drops back to 3ft from the west, but look – you get glassy conditions. That’s a big deal. The wave comment says it’s surfable but ordinary, and I’d agree; the energy is weak (85), but if you’re desperate for a paddle, that’s the first real chance. By Sunday morning the 13th, the swell pushes to 3ft with a longer 11-second period, giving us moderate energy (244), but the cross-onshore wind kicks in by afternoon with 15 mph winds, so it gets chopped out fast. Monday morning the 14th is clean with a light cross-offshore east breeze on a 3ft west swell, but again, it’s just ordinary.
Now, there’s a gap of a few days where the wind just ruins it – Tuesday the 15th has a 22 mph cross-shore, and Wednesday the 16th morning is clean but only 5ft – that’s the best of the first week, but it’s still just labelled as marginal. Nothing to get excited about.
The real standout? You have to look out towards Friday the 25th of September. That morning, a solid 7ft west swell rolls in with a very long 14-second period. The combined energy is a massive 1884 – that’s strong, powerful stuff. It’s clean with a moderate cross-offshore east wind. This is expert territory: over 8ft means it’s only for the experienced crew. That long-period groundswell will make waves a bit more lined up, but at a beach set-up like Le Kerou, it might break a bit too straight. Still, for the bold boys and girls, that’s the best on offer. Saturday morning the 20th is another tiny clean window (2ft), but it’s just not in the same league.
Overall, this spot’s pretty quiet for the next week and a half. The water temp is 66° – a touch warmer than normal for this time of year. We’re in for a long wait, but that last Friday pulse could be a ripper if it holds. Keep an eye on it.

A general guide to surfing at Le Kerou can be found by selecting the local surf guide option on the grey menu.

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 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. 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.
