The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks.
Honestly, it’s a slow start. We’ve got a long gap of nothing special for the first few days. The first surf worth talking about doesn’t show until Sunday the 13th of September at Le Kerou. The early session that morning is the standout: clean glassy conditions with a west swell at 3 ft and a period of 11 seconds. Combined swell energy is sitting at 240 – moderate, but the smooth surface makes up for it. That’s the pick of the day – a little gem for a beginner-friendly wave. It’s a beachbreak that’s exposed to the west and works best with that direction. The wind is calm, the vibe is quiet. You’ll want to be out there early.
After Sunday morning, things fall apart fast. The afternoon turns to cross-on slop, and Monday the 14th stays small and ordinary. Tuesday and Wednesday are tiny and messy. Wednesday the 16th does see a jump in size with a 4 ft morning, but it’s short-period and cross-off – not awful, but not logging it as a standout.
Then we finally get a real moment. Sunday the 20th of September morning – mark it. Offshore wind from the north-northeast, 5 ft west swell with a long 15-second period, and the combined energy is pumping at 984. That’s a strong, clean groundswell. Le Kerou will have shape and push, but keep in mind, that long period tends to run straight on beach breaks so look for a rip or a gutter to help you out. Still, calm offshore and that size – it’s the best of the whole outlook. Monday the 21st morning is similar, a touch smaller at 4 ft, but still clean with offshore wind and a sweet 14-second period. Both mornings are solid.
After that, the swell fades fast. From Tuesday the 22nd onward it drops below 3 ft, and the energy just drains away. By Thursday the 24th we’re down to 1 ft and barely a ripple. That’s it for the 16-day window.
Overall, if you can get out Sunday the 13th morning or the Sunday the 20th and Monday the 21st mornings, you’re timing it right. The rest is mostly flat or messy.
Rusty.

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

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.
