The Lowdown
Right, Rusty here again. Let's break down the same forecast in old-school numbers.
The first week and a half is a total bust. There’s a gap of nearly two weeks with no real rideable waves. The water is a balmy 79°, which is way warmer than average for this time of year, but there’s just no energy in the water to make it worthwhile.
The only break on the radar is Cassis - Plage de l'Arène. It’s a reef setup that’s famously inconsistent, and it needs a proper swell to wake up. For most of the forecast, the wind is either messy or the waves are flat.
The one real highlight, and it’s a long-range call, is Monday the 17th of August. The forecast is showing a pumping 11.5ft groundswell out of the west-northwest, with a period of 8 seconds. That’s a ton of power, and the combined energy is off the charts (1331). The wind is predicted to be glassy in the morning, which is pure magic. This is strictly for experts. The morning of Tuesday the 18th also looks special, with the same size swell and a clean offshore wind from the east-southeast. Expect this spot to be packed, as it’s often busy, and a swell like this is a rare treat.
So, a long flat spell, then a couple of days of giant, glassy swell that’s only for the brave. It’s a waiting game, but it could be a good one.
