The Lowdown
Alright folks, Rusty here, giving you the long-range look at Playa de San Lorenzo.
The next couple of weeks are a bit of a mixed bag. We've got some real good windows of clean surf coming, but also a few days where you'll want to stay on the beach. The water's sitting at 70°, which is a touch warmer than normal for this time of year, so that's a nice bonus for the skin.
We've got a bit of a lull right now. The first real action worth getting excited about hits on Monday, September 7th. Early morning, the wind drops to glassy, and we're looking at clean, waist-high waves from the NW at 3ft. The period is a long 13 seconds – that's proper groundswell energy, giving the waves some real shape. It won't be massive, but it'll be clean and fun. This is a good one for a relaxed session.
Tuesday the 8th is small and messy, but then Wednesday the 9th sees a pulse of energy. The morning looks prime – glassy conditions again with a NNW swell building to 5ft. The period is a shorter 8 seconds, so it'll be a bit more crumbly and less powerful. It could be a bit punchy for beginners at that size, but a solid option for the intermediate crew. The afternoon gets a bit bigger, up to 6ft, but the wind swings cross-on, making it choppier.
The standout in this whole run looks to be Thursday, September 10th morning. We've got a clean 5ft from the NNW, glassy conditions – absolute perfection for the lineup. The wind flat, it'll be peaky and fun. Get on it.
After that, it fades into a bit of a lull through the end of next week. We see smaller swells and mostly cross-on winds until around Sunday the 13th, when a new, longer-period NW swell shows up at 5ft to 5ft with a 12-second period. The catch is the wind is cross-on, so it won't be as clean as that Thursday morning, but the energy will be there.
Looking further out, the real highlight might be the Friday, September 18th morning session. That's a full week and a half from now, so it's less certain, but the models are showing a solid 6ft swell from the NW with glassy conditions. If that holds, it will be the best day of the period by far – clean, solid overhead waves for the experienced crew.
So, in short: get out on Monday morning the 7th for a clean warm-up, and absolutely do not miss Thursday the 10th morning – that's your top pick. The Friday the 18th is the long-range dreamer to keep an eye on. The rest is mostly marginal, with a few decent windows.
