The Lowdown
Alright, let’s run it back in feet and miles per hour for the same stretch at Le Kerou.
First week’s pretty bleak – onshore junk and weak surf. Not worth wettin’ a suit until around Saturday, September 5th.
That Saturday morning, September 5th brings the first real hope. Swell runs about 3-4 ft outta the west, period a solid 13 seconds – that’s groundswell, long lines but longer waits. Wind is clean offshore from the ENE at just 6 mph. Combined energy sits at 392, moderate for that height. Water temp is about 66°F, right where it should be for early September.
Thursday morning, September 10th sees a bump to 6-7 ft from the WSW, but period drops to a weak 7 seconds – windswell junk. Cross-off wind from the NNW at 12 mph keeps it clean, but that size is expert-only. Energy reads 404, short and dumpy.
The best of the bunch is Saturday morning, September 12th. Swell is 4-5 ft from the west, period 11 seconds, with a light offshore breeze from the east at 6 mph. That’s clean, lined-up, and user-friendly. Combined energy is 483.
Monday morning, September 14th is a glass-off special – flat calm, zero wind, with a 4 ft west swell at 9 seconds. Energy is 306, smooth and clean as it gets.
Later on, Tuesday morning, September 15th has a 5 ft west swell with an extreme 15-second period – very long groundswell at 1278 energy. Wind is light cross from the WNW, but that period will make it walled and straight at a beach break.
And Thursday morning, September 17th pumps up to nearly 8 ft from the west, period 9 seconds, with cross-off wind from the NW at 12 mph. Energy hits 1592 – that is strong. Experts only.
Best bet is Saturday the 12th for clean, fun surf with that long-period groundswell and offshore wind. Close second is the glass-off on Monday the 14th. Long-range looks big but tricky.
Keep an eye on the sky.

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.
