The Lowdown
Alright, folks, Rusty here. Let’s break it down. The next couple of weeks are a bit of a slow burner, but there’s a solid window if you’re patient.
The first sniff of surf comes Friday afternoon, with a 6ft swell from the NNW, period of 10 seconds, and moderate energy (655). But the wind is a cross-offshore, and it’s looking marginal. Not worth paddling out for.
Saturday and Sunday are a total dud – tiny, weak, and windy. Monday through Wednesday next week is flat and clean, but there’s nothing to ride. Save your wax.
Then, the storm hits. On Thursday the 27th, the swell jumps to 7ft in the morning, pushing to 8ft in the afternoon from the NW, short period of 8 seconds, and strong energy (957). It’s a risk of thunderstorms and a fresh cross-offshore. This is a powerful, crumbly wave, best left for the hardcore crew on a reef or point. Too big for beginners.
The best of the bunch is Friday morning, the 28th of August. A clean 5ft swell from the NW, period of 9 seconds, with moderate energy (431). The wind is glassy offshore from the WSW. The water is a touch warmer than usual. This is the one – clean, lined-up waves at El Sardinero - Primera. It’s fairly consistent, but crowds are likely, so get in early. The swell direction is a bit off the optimum N, but that glassy wind will make it special.
Saturday the 29th morning is also decent with 5ft NW swell and a clean cross-offshore, but Friday morning has the glassy edge.
The long-range looks promising for Thursday the 3rd of September. A solid 7ft NW swell with a short period (8 seconds) and glassy conditions in the morning. That’s a lot of energy (499) for a beach break, so it’s powerful and dumpy, strictly for experts. This one is promising but less certain.
So, the verdict: the first few days are a skip. The clear winner is Friday morning, the 28th of August. That’s your best bet.
Rusty.
