The Lowdown
Alright, Rusty here, let's get into what's on offer for the next couple of weeks. Things are looking pretty quiet to start, so we've got a bit of a wait on our hands.
The first week is mostly a write-off for any real surfing. We've got a long stretch of poor conditions with onshore wind and weak, messy swell. The first session that even gets a sniff of a wave is Friday the 18th, but it's pretty marginal. There's a 3ft swell coming from the W with a very long 16 second period, and the combined energy is 513 (moderate wave energy). The wind is light from the NNW, so it's cross-onshore, which keeps things a bit bumpy. Given that long period, this is really more of a point break or reef wave, and at Rade de Croisic, which is an exposed spot, it might be too straight to really line up. This one's a bit of a maybe.
Sunday the 20th morning is another slight lift. Swell drops to 2ft from the W, 11 second period, and the energy is down to 112 (weak). The good news is a light NNE wind gives us a cross-off breeze, so the surface will be clean. It's small and ordinary, but surfable.
There's a massive gap then until the 23rd of September. On Wednesday the 23rd, things finally look like they're coming together. The morning has a strong 19 mph offshore wind from the E, but that’s a fresh breeze, making it tricky. The swell is 2ft from the WSW with a very long 15 second period, and the energy is 253 (moderate). It's a marginal forecast because of the wind, but the potential is there. The real standout is the afternoon. We see an offshore wind from the E at just 6 mph, making for a clean, light breeze. The swell builds slightly to 3ft from the W with that nice 14 second period, and the energy is 232 (moderate). This is the best we're going to get. Expect good surf conditions with clean lines.
For the rest of the run into October, it's small and mostly unrideable. Thursday the 24th has small clean waves but very ordinary conditions, and by the end of the month it's all onshore slop or tiny glassy dribble.
So if you're keen, pencil in the afternoon of Wednesday the 23rd at Rade de Croisic. The water's about average for this time of year, so nothing unusual there, just wetsuits as normal. It'll be small, but clean and with good shape for a little longboard or a mal. Between now and then, it's mostly a waiting game.
Rusty.
