The Lowdown

Alright, let's see what Le Kerou is serving up. The first week's menu is pretty thin, but there are a couple of standout dishes later on that are worth saving your appetite for.

The water's running a touch warmer than usual for the fall, around 66°, so you should be fine without a full winter suit for now.

Right off the bat, Monday morning (September 14th) is a non-starter. We're looking at a weak 3ft west swell with a 9-second interval. It's glassy, but there's no grunt behind it. Don't bother.

The pattern stays pretty hopeless for the rest of the week. Small, choppy, and onshore winds just trash any chance of a decent wave. Wednesday afternoon (September 16th) does see a jump to a 6ft WNW swell with a 10-second period and a moderate cross-offshore wind, so it's clean, but the vibe is still marginal. It's got decent energy (1114), but it's not clicking for a good session.

Friday the 18th brings more size – 5ft from the west with a very long 16-second period, giving it strong energy (1321). But the wind is cross-onshore and it's lumpy. That long-period groundswell is much better for a point or reef break, and since Le Kerou is an exposed beach, it's likely to be too straight and hard to get into. Wrong spot for it.

The first real gem shows up a week out, on Monday morning, September 21st. The wind goes light and cross-offshore from the ENE, leaving the surface clean as a whistle. We've got a solid 4ft west swell with a nice 14-second period. The combined energy is a healthy 577. This should produce some really good, well-shaped, powerful waves. This is the session to circle on your calendar.

A bit further out, Sunday morning the 27th of September looks like a heavy swell. We're talking a 7ft swell from the WSW, but with a shorter 10-second period. The combined energy is very strong (856) and the wind is a gentle offshore from the ESE, so it'll be clean. That's a lot of water moving.

But listen to this: the very next day, Monday the 28th, the swell pumps up to 10ft from the WSW. The forecast flat-out says it's predicted to be too big for this break. That's strictly for the big-wave crew. Even with a light cross-shore wind, it's going to be a chaotic close-out zone for everyone else.

So, my top tip is that Monday morning (September 21st) – clean, powerful, and with long gaps between sets to make the paddle out easy. The Sunday the 27th is a solid second pick, big and clean, but you'll want your biggest gun.

The rest of the run is a total washout. Cross-onshore slop and tiny dribble.

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.
