The Lowdown
Alright folks, Rusty here. Let’s get real about the waves at El Sardinero. This forecast is a tough read. We've got a long stretch of flat, messy, and plain ugly conditions, with just the faintest flicker of hope at the very end. Keep your expectations low.
For the first week and a half or so, it's basically a ghost town. There's just no power in the ocean. We're talking days of tiny, weak slop with no push behind it. The energy numbers are pathetic, often in the single digits (like 2, 8, 9) or just zero. To give you a timeline, from the 16th through the 28th, there is nothing that even comes close to a green light. It's a brutal stretch of flatness. You'll see a few 1 to 2-foot bumps, but they're short-period and all over the place. We even get some cross-onshore breezes making it all choppy and uninviting.
There's a slight change of pace early on the 29th, but it's nothing to write home about. The swell finally shows up, but the quality is just "meh" at best. It’s not exciting, but it's the only option. The energy finally starts to build, going from 156 on Saturday morning to 257 by Sunday morning, so there's at least some more push. But with wave heights around 4 feet, it's still small and won't offer much.
The standout, and I use the term loosely, is the Sunday morning session on the 30th of August. The forecast shows a 4-foot west-northwest groundswell with a 10-second period, and the wind is light and offshore. That's the cleanest window we get all period. The swell's not big, but it'll be the most organized and cleanest surf of the whole run. It's still going to be small, so if you're an intermediate, you might scratch out a few fun ones, but it's nothing to get stoked about.
The rest of the second week is more of the same—small, messy, with wind and showers getting in the way. Honestly, if you're a beginner, this whole 16-day window is a no-go. The waves are barely ankle-biters for the most part, and even the "bigger" days are not working for you. For everyone else, it's a waiting game. A long one.
Keep the boards waxed, but they might be better off gathering dust for a while. This is one of those times where patience is key. The surf will come back, it always does, but it's not looking like it's in any hurry.
Rusty.
