The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up for the Cassis area. I gotta be straight with you – this outlook is a tough one. We’re looking at a long stretch of very small to flat conditions, so don't get your hopes up for anything special for a while.
For the first few days, from Monday the 10th right through to the end of the weekend on the 16th, it’s almost completely flat. We’re talking tiny wind swell bumps at best – waves around 1 ft with a weak, short period of just 4 seconds. The combined energy is pitiful, barely reaching double digits (5 to 12). The surf is just poor. There’s a glimmer of hope early on Monday the 10th with glassy conditions and light easterly winds, but with no real swell to work with, it’s a flat calm. You’d be better off swimming.
We finally see a pulse of energy arrive around Tuesday the 18th. The swell bumps up to 6 ft from the WNW, with a period of 6 seconds and a combined energy that jumps to a moderate 170. That’s the most size we’ll see, but it’s not clean. The wind is cross-offshore from the NW on the Tuesday morning, which will clean it up a bit, but the afternoon turns messy with a cross-onshore. The waves are still labeled as poor. This size, 6 ft, is pushing into the zone that’s too much for beginners.
The pick of the whole 16-day run looks like Wednesday the 19th and Thursday the 20th. On Wednesday morning the 19th, we’ve got a 4 ft swell from the WNW (period 5 seconds, combined energy 88) with a light offshore breeze from the N. The report says the conditions are clean and it’s “surfable waves but very ordinary conditions.” It’s not epic, but it’s the best we’ve got. Then Thursday morning the 20th is also worth a look: 5 ft from the NW (period 5 seconds, combined energy 115) and glassy conditions with a light offshore from the ENE. This is your best bet. That said, these are very ordinary waves, so keep the expectations in check. The water temperature anomaly is about average for this time of year.
After that, it drops right back off. By Friday the 21st through the end of the period on the 25th, we’re back to tiny, weak swell and mostly poor or onshore winds. Saturday the 22nd morning starts glassy with a tiny 2 ft from the WNW, but it’s not going to be worth paddling out for. The whole second week is a dud.
Remember, Cassis - Plage de l'Arène is an inconsistent reef break, so this kind of blank run isn't unusual. It's best for beginners when there's swell, but this window offers very little. Keep an eye on the forecasts; things can change.
Rusty, signing off.
