The Lowdown
Alright, Rusty here. Let’s have a look at what’s doing at Le Kerou.
First thing first, the water is sitting at 66°F, which is just about normal for this time of year, so nothing freaky going on there.
The forecast starts off rough. Monday the 31st of August is a write-off: we’ve got a 7ft swell from the WSW, but the wind is howling 12-19 mph cross-on, and the combined energy is a meaty 874 (moderate) jumping to 1643 (strong) in the arvo. The wave comment says it all – poor surf conditions. Not worth a paddle.
Tuesday the 1st of September is a tease. The morning goes glassy, winds are 0 mph, and we have a 3ft leftover swell from the W with a 9-second period. The combined energy is only 169 (moderate), which is weak, but it’s clean. The wave comment says “surfable but very ordinary.” It’s about the only window in the first week, but honestly, it’s not enough to get excited about.
Then we hit a long dry spell. From Tuesday afternoon all the way through to Friday the 4th, it’s onshore, cross-on, and tiny – 1ft to 3ft. The wind is out of the SW or WSW, never less than 6 mph, and it’s choppy. No surf worth chasing.
Saturday the 5th of September is the standout. The early morning is the one to be on. We have a 4ft groundswell from the W, with a period of 13 seconds, pumping in with a combined energy of 581 (moderate). The wind is light from the N at 6 mph, cross-off, which means clean waves. The wave comment literally says “expect very good surf conditions.” This is the best of the whole 16 days – a proper long-period groundswell with clean conditions. The swell is a bit too big for beginners, but intermediate to advanced surfers will be smiling. The crowd factor at Le Kerou is “sometimes,” so you might have some company, but it’s not a zoo.
It’s a shame the afternoon goes sour – the wind swings WSW 16 mph cross-on and it gets lumpy, so make the most of the morning.
After that, things drop off again. Sunday the 6th is a tiny 2ft clean morning, but it’s low energy. From Monday the 7th through to Thursday the 10th, the wind is onshore or cross-on most of the time, with only small, weak swells (2ft to 4ft, periods of 8-13 seconds, combined energy 33-202). The best of that bunch is Tuesday the 8th morning – a clean 3ft from the WSW with a 11-second period and 202 energy (moderate) – but it’s very ordinary.
The second week has a few more clean mornings, like Friday the 11th and Saturday the 12th, but the swell is tiny (2ft to 3ft) and the energy is low. Sunday the 13th is offshore but only 2ft. Not really worth a session.
Monday the 14th of September morning shows a bit of life – 3ft from the WSW with a 10-second period, combined energy 215 (moderate), and gentle offshore wind from the NE. That’s clean and surfable, but not a standout. The afternoon brings a 5ft long-period swell (16 seconds, 1049 energy – strong!), but the wind is cross-on, so it’s messy. That’s a frustrating one.
Tuesday the 15th is the last day of the forecast, and it’s a stormy one – 5ft to 6ft from the W and WNW, with strong cross-on winds and combined energy up to 1808 (strong). That’s a powerful, chunky mess. Not for paddle surfing. If you’ve got a kite, maybe, but for a surfboard, leave it.
So, to sum it up: the only true standout is Saturday the 5th of September morning. That’s the one to circle. The rest of the 16 days is mostly small, windy, or ordinary. The first week has a big gap of poor surf from Monday to Friday, so don’t hold your breath.
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.
