The Lowdown
Alright, let’s break it down.
Looking at Le Kerou, it’s a real mixed bag over the next 16 days. The first part of the forecast is a straight-up struggle. There’s not much to get excited about.
On the 6th of September, we’ve got a 2ft westerly swell, period at 10 seconds, but a side-offshore breeze kills it. The energy is weak – just 94 – so it’s not worth suiting up. Monday the 7th sees some size come in, with 4ft to 5ft from the west-southwest, period stretching to 13-14 seconds, bumping the energy up to 523 to 648. But it’s all onshore wind, so it’s choppy and poor.
Tuesday the 8th is still marginal. The afternoon offers a glimmer: 4ft west-southwest swell, 10-second period, with a cross-off wind from the north-northwest. Energy drops to 230, but it cleans up. Still, it’s just “surfable,” nothing special.
From Wednesday the 9th all the way through the 17th, it’s a rough ride. A lot of onshore wind, short-period junk, and messy surf. The 11th has a 6ft westerly swell, but it’s onshore with a period of only 8 seconds, giving 673 units of energy – a lot of push, but no shape. The 15th packs 5ft of west-northwest groundswell, period at 11 seconds, with 720 energy, but again, the wind is onshore, blowing it out.
Then we get to the 18th of September. This is the big one. Thursday morning shows a solid 7ft west-northwest swell, period at 11 seconds, and the combined energy rockets to 1624. The wind is light and side-on. That’s serious power – expert-only territory. It’s the standout for size, no doubt.
After that, things clean right up. The 19th of September is the real gem. Saturday morning brings 4ft of west swell, 10-second period, and an offshore wind from the northeast. That’s clean. Energy is 279. Then Saturday afternoon goes glassy. Zero wind from the south, with 4ft west swell and a 10-second period (260 energy). That’s the session you wait for. For a spot that can get crowded sometimes, that glassy window is golden.
Sunday the 20th is also worth a look. Morning has 3ft with a side-offshore breeze (164 energy), and the afternoon picks up to 3ft from the west, 12-second period, light side-offshore, and 280 energy. Clean again. The 21st stays side-offshore, but the quality fades.
So, bottom line: the first week is a bust. The real standout is Saturday the 19th, especially the afternoon glass. The 18th morning is for the big-wave crew only. Don’t bother before that.
