The Lowdown
Alright, let’s talk about Le Kerou. It’s a bleak 16-day outlook, to be honest. There’s a big gap of nothing from the start until the 26th of August. For over a week, the wind is a nightmare – mostly onshore or cross-on – and the swell is tiny. The combined wave energy is mostly in the low double digits (10 to 155), which is weak. If you’re a beginner, you might get a few knee-high waves on the morning of the 22nd when the wind goes offshore and it’s glassy, but it’s only 0.6m from the W, with a period of 8 seconds. It’s not a standout.
The one real highlight is the morning of the 27th of August. We’ve got a 2.0m swell from the WSW, but the period is only 7 seconds, so it’s a short-period wind swell. The key is the wind: it’s glassy, dead calm, so it will be clean. The combined energy is 417 (moderate), and the water temperature is 21°C, which is much warmer than normal for this time of year. That’s a big deal. The break is exposed to the W, and the swell is from the WSW, which is close to the optimum direction. It’s a good, fun session for a beginner to intermediate, but it’s not a powerful groundswell.
After that, the wind kills it again. The 28th of August brings a big 3.0m to 3.5m swell from the WSW, but with a strong cross-on wind, it’s going to be a lumpy, choppy mess. The combined energy is massive (1221 to 1806), but it’s too big for a beginner, and the wind is bad. The 29th has a 3.0m swell from the W with a long period of 12 seconds, but the wind is cross-shore and the energy is extreme (3030). That’s a powerful swell that will be breaking straight at a beach break, so it’s not the best spot. Only for experts, and even then, the wind is a letdown.
The morning of the 30th has a 2.1m swell from the WSW with a light onshore wind, but it’s a marginal call. The 31st has a 2.2m swell from the WSW with a cross-shore wind, but it’s not clean.
So, the only standouts are the glassy morning of the 27th for a clean, fun-sized wave, and maybe the 22nd morning for a tiny, clean beginner wave. The rest is poor. The surf is weak, the wind is mostly onshore, and the big swells are too big and messy. It’s a tough stretch.

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.
