The Lowdown
Alright, let’s switch it up for the imperial crowd.
Honestly, the outlook here is quiet for a long stretch. We’ve got a serious dry spell for Le Kerou – nearly two weeks of onshore junk and poor conditions before anything decent comes along.
From Tuesday 25 August through to Saturday 6 September, don’t bother. The wind is mostly onshore from the SW, WSW, or S, with speeds between 9 and 25 mph. Even on the 27th when there’s a 5ft swell, it’s accompanied by onshore wind and rated as poor. The combined wave energy is weak to moderate for that whole first block, with readings like 44 on the 25th and up to 479 early on the 27th.
Your only real window shows up on the morning of Sunday 6 September. That morning looks clean, with a light offshore breeze from the ENE at just 6 mph creating a glassy surface. The swell is a small 3ft from the west, with a long period of 10 seconds, giving it some groundswell punch (combined energy of 239). For a point or reef break like Le Kerou, this is the sort of clean, lined-up swell that gets you out of bed early. The water temp is around 65°F, pretty typical for now.
After that, the forecast gets tricky again until Tuesday 8 September when a big, long-period groundswell arrives. The morning shows a 7ft south-west swell with a very long period of 16 seconds and a combined energy of 4351. That’s powerful, but the wind is onshore from the WSW at 9 mph, so it won’t be clean. By the afternoon, it’s a huge 12ft (6647 combined energy) – too big for this break unless you’re an expert, and still onshore.
So, mark your calendar for the morning of Sunday 6 September. That’s the one clean, offshore morning. Everything else is either blown out or a beast only for the brave.

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.
