The Lowdown
Alright, Rusty here. Let's be real about this stretch for Cassis - Plage de l'Arène. It’s a reef set-up that wants a solid SW bump, but the ocean is flat-out snoozing for most of this forecast.
Right now, we're looking at a huge dry spell. For the first week and more, the wave energy is literally zero, or just tiny bumps that won't get you out of your wetsuit. The water is sitting at 21°, right where it should be for this time of year.
The first real pulse shows up on Thursday, September 17th. We get a swell of 1.5m from the WNW, but with a short 5-second period and a stiff 25 mph cross-shore wind. The wave energy picks up some (125), but that wind is going to wreck the surface. The afternoon is the same story – 1.5m, 6-second period, but the cross-shore wind hits 30 mph, making it a choppy, lumpy mess.
Friday the 18th is a letdown, too. Swell drops to 1.1m from the WNW, still a short 5-second period, and still that annoying cross-shore wind making things choppy.
The only moment of peace is Saturday the 19th morning with a slight offshore wind, but the swell is a tiny 0.7m. Not worth the paddle. Then we hit a massive wall. From the afternoon of the 20th of September all the way until the 28th, it’s flat as a pancake. Day after day with zero wave energy.
We finally get a whisper of life on Monday the 28th of September: 0.3m from the SW under glassy conditions. Then the real "best" of a bad bunch comes on the 30th of September. The morning shows 0.6m of SW swell with glassy winds. The period is short, just 6 seconds, and the energy is weak (36). It’s tiny and inconsistent, but after two weeks of nothing, a clean 0.6m at Arène is the only game in town. It's not exciting, but it’s surfable.
So, don't plan a trip. The first ten days are a bust. The 30th is your only real chance for clean waves, and it's a small, long-range hope. The reef needs more grunt than this.
Rusty.
