The Lowdown
Alright, let me take a look at what we've got here for the next 16 days.
Honestly, I gotta be straight with you—this stretch is looking like a major bust. We're kicking off this Thursday morning the 20th of August with rain showers and a messy 5ft cross-onshore swell from the west, and it just doesn't get much better from there. The wind is all over the shop, and the wave energy is weak to moderate at best, with the combined energy barely cracking 308 in the early going. The water temp is running about average for this time of year, so at least don't need a steamer, but that's about the only good news.
We've got a long, dry spell here. From Thursday the 20th, right through to the end of August, the surf is just plain poor. You'll see some small pulses—like Friday morning the 21st gives us a 4ft swell from the west with a 10-second period, but the wind is cross-on, and the energy is only 219. It's a no-go. Saturday morning the 22nd cleans up a bit with a light cross-offshore east wind, but the swell has dropped to a pathetic 2ft. There's a couple of days with offshore winds, like Sunday the 23rd morning with a clean 1ft wave from the WSW, but honestly, you'd need a longboard and a prayer.
The only real glimmer in this whole 16-day window is on Thursday the 3rd of September. That morning, we finally get a setup worth talking about. Guidel Plages, which is a beach and reef setup exposed to the southwest, will see a 6ft swell from the southwest, with a 9-second period, and the wind is coming from the east-southeast as a cross-offshore breeze. The combined energy is a solid 627, and the report calls for *very good surf conditions*. This is the standout. The waves will be clean, with that offshore wind grooming the faces. It's a beginner-friendly height, and the direction is spot on for the break. But listen, this is a long-range call, so keep your fingers crossed.
Outside of that Thursday morning, the rest of the first week of September is still looking rough. There's a bit of a pulse on the 4th of September with a 7ft swell from the west-southwest, but the wind is onshore and the conditions are marginal. That's expert territory if it cleans up, but it's a big if.
So, bottom line: we've got a massive gap of almost two weeks of junk. The one bright spot, and it's a promising one, is that Thursday the 3rd of September. If you can wait it out, that's your window. Otherwise, leave the boards in the shed.
