The Lowdown
Alright, let’s switch it up for the imperial crew. Same story, different numbers.
We’ve got a seriously tough stretch of weather ahead for the Cassis area. The surf window is essentially closed for a long while.
There’s a big gap of nothing happening until the first real hope pops up on Saturday, September 5th. The swell is tiny, barely reaching 1 ft from the NW. The combined wave energy is a weak 64, so don't expect any push. The wind will be light out of the North, leaving the water clean, but you are looking at a short-period mess of only 5 seconds. It is a barely surfable wave, and only for the absolute beginner.
The one other moment to keep an eye on is the morning of Tuesday, September 8th. The swell gets to about 5 ft from the NW, which is a bit of an uptick, but again, the period is pretty short. However, we get a proper offshore breeze from the NNW, which will clean everything right up. The energy is moderate at 194. Because the waves are over 5 ft, it is territory for the experienced surfer, not the newbie.
Water temp sits in the low 70s, totally normal for the season. Plage de l'Arène is an inconsistent spot, so these long gaps with only a couple of okay-ish options are just how it goes here. The crowds might show up when it's rideable, but honestly, with quality this low, it'll probably be quiet.
