The Lowdown
Right, let’s have a look at what’s coming up for Le Kerou, then. It’s a bit of a mixed bag for the next couple of weeks, to be honest. The forecast is pretty bleak for the first week and a half, with a lot of onshore wind and poor surf conditions. The real standout is a late burst of proper swell right at the end of the window. The water temp is about average for this time of year.
The first solid recommendation doesn’t show up until Wednesday the 16th of September. That morning, the wind swings offshore from the NNE with a light breeze, and we’ve got a 5ft swell coming from the WSW, with a period of 11 seconds. The combined energy is moderate at 828 – it’s not huge, but it’ll be clean and pretty fun for a beginner-friendly spot.
Then, the big one. Thursday the 17th of September is the clear standout. The morning session is where it’s at. A clean 7ft swell from the WNW, period of 10 seconds, and a light offshore breeze from the ENE. The combined energy is strong at 1540. That’s a solid, powerful groundswell, and with the winds being clean, it’s going to be good. That’s a bit on the bigger side – over 8ft means it’s for experienced surfers only. The swell direction is almost bang on the optimum for the break, which is West.
After that, Friday the 18th and Saturday the 19th of September offer cleaner conditions in the mornings with lighter winds and smaller, more manageable waves around 4ft to 4ft, but the energy drops way off. The wind is offshore, so it’ll be tidy, but nothing to write home about.
The rest of the period is pretty quiet. There’s a long gap of nothing much before the 16th, and after the 19th, it fades out again. A few small, clean days on the 21st and 22nd, but the swell is weak and short-period, so it’s not going to get the heart pumping.
For the best of the lot, you’ve got to aim for the morning of Thursday the 17th of September. That’s the one. It’s a long way out, so keep an eye on it, but that’s the window to clear the diary.
