The Lowdown
Alright folks, Rusty here, in imperial. Let’s talk about Cassis - Plage de l'Arène. This reef break is looking like a long, quiet stretch with very little to get excited about for the next 16 days.
Wednesday and Thursday are a washout. The wind is all over the place, cross-shore and strong, with lumpy, choppy water. The swell is there but it’s messy. The water temp is about normal for this time of year. By Friday, the swell drops to a tiny 3 ft, but it’s still cross-shore and messy.
The only real window comes on Saturday the 12th of September. The morning shows a 4 ft NW swell with a light cross-offshore breeze from the NNW. It’s clean. The combined wave energy is moderate (103). It’s the best we’ll see, but it’s inconsistent here, so it’s a gamble. A few clean waves, maybe, but it’s nothing to write home about.
The rest of the forecast is flat. The 13th has a tiny 1 ft swell in the morning with offshore wind, but it’s too small. The 14th is similar. From the 15th through the 24th, there’s almost no swell at all. A few glassy mornings with zero energy, like the 17th and 22nd, but the swell is basically non-existent. The 16th has a 0.3 ft swell, the 17th a 0.7 ft, the 18th some 3 ft, but it’s all tiny and weak.
The Saturday the 19th has a glassy morning, but only a 1 ft swell. It’s flat. The 21st has a 4 ft NW swell, but it’s onshore and messy. The 22nd has a glassy morning with a 2 ft NW swell, but that’s it. The 23rd and 24th are flat again.
The standout, if you’re keen, is the Saturday 12th morning. That’s your best shot. It’s a small, clean session for a beginner or someone who just wants to paddle out. The swell is from the NW at 4 ft, and the wind is light cross-off, so it’ll be clean. But it’s inconsistent here, and it’s not going to be a proper wave.
For the rest of the time, it’s a long, drawn-out flat spell. It’s a blank run, and that’s normal for this area when the swell window is closed. Keep an eye on the charts, but don’t get your hopes up.
Rusty.
