The Lowdown
Alright folks, Rusty here. Let’s have a look at what Le Kerou has in store for us over the next couple of weeks.
Right off the bat, Tuesday the 8th is a write-off. We’ve got a messy 7ft to 8ft swell from the WSW, but the wind is absolutely howling onshore or cross-shore, making it a total slog. The water’s sitting at 66°F and is a touch warmer than normal for this time of year, but that won’t matter when you’re getting blown off your board.
Things start to look up on Wednesday the 9th. The morning is your best bet: a clean 4ft swell from the WSW with a light cross-offshore breeze from the NNW. The wave energy is moderate (397) and the 9-second period will give you something to work with. It’s not massive, but it’s surfable and clean. The afternoon gets choppy and cross-on, so make the morning session.
Thursday the 10th is flat and weak – don’t bother. Friday the 11th morning is a repeat of Wednesday: clean 4ft WSW swell, light cross-off wind, and moderate energy (243). It’s the same good window, but again, it’s small.
After that, we hit a dry spell. From Saturday the 12th through to Monday the 16th, it’s a mix of tiny waves, onshore winds, and marginal conditions. There’s a moment on Monday the 14th morning where it goes glassy with 3ft of swell, but it’s just ordinary – not worth paddling out for.
The standout comes on Thursday the 17th morning. We get a solid 5ft groundswell from the W, with a clean offshore wind from the NNE, and the energy is moderate (397). The 9-second period will give you decent shape. This is the best on offer in the whole window – clean, rideable, and with a bit of push. The afternoon sees a bump to 6ft from the WNW, but the wind swings cross-on, so it gets a bit bumpy.
After that, it’s back to small, clean but weak surf from the 18th through the 20th. The 21st of September brings a long-period 17-second swell from the WSW at 4ft, but the wind is a strong cross-onshore mess (25 mph), so skip it. The 22nd is similar but with a choppy cross-shore wind. The run ends on the 23rd with tiny, clean but weak waves.
So, to sum it up: Wednesday the 9th morning and Friday the 11th morning are your shoulder-high, clean windows. But the real winner is Thursday the 17th morning – that’s a solid 5ft with offshore wind. Get on it.
Rusty.

Information about the Le Kerou Surf forecast
The above surf forecast table for Le Kerou provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Le Kerou) 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 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.
