Las Piscinas Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into the local outlook for Las Piscinas.

It’s a tough start, I’m not gonna lie. For the first week, from now through the 13th of September, we’re looking at a real desert. The swell is bumpy, short-period, and the wind is on it or cross-onshore, keeping things choppy and messy. The wave energy is moderate at best, peaking around 552 (moderate energy) on the 12th, but with a 6ft swell and a period of just 8 seconds, it’s gonna be a wall of whitewater. The wind is onshore at 16 mph that afternoon, so it’s a write-off. There’s a consistent 5ft to 6ft of swell here, but it’s all poor quality. For a solid week, there’s nothing worth paddling out for.

Now, hold on, because this is where it gets interesting. The standout window is the 14th of September, Monday morning through Tuesday morning. The wind drops to glassy, absolutely dead calm from the ESE and NW. That’s a major positive. We see a new swell arrive from the NNW, with a period of 11 to 13 seconds. That’s a proper groundswell. The swell height is small, only 2ft to 2ft, but that long period will give it some punch and shape, especially on a reef setup like this. The water temperature is sitting at 75°, which is about average for the time of year. The wave energy is moderate (268 on Monday morning, dropping to 158 by Tuesday morning), but the main selling point is that glassy, clean surface. The break is consistent, so with those conditions, it’s the best we’ll see. However, it’s a reef break, and with a long-period swell over 11 seconds, expect it to be a bit more critical and line up well. The wind is offshore from the NW on Monday afternoon, which is exactly what we want. Crowds are listed as "often", so expect company.

The only real standout is the 14th of September. Monday morning and afternoon are the pick. The swell is from the NNW, 2ft-2ft, with a 12-13 second period, and glassy conditions. It’s small, but it will be clean and fun. Tuesday morning (15th) is still glassy, but the swell is a touch smaller and the period is dropping to 11 seconds, so it’s a second-tier option.

After that, from the 15th afternoon onwards, it’s back to the struggle. The wind swings onshore again, the swell drops below 3ft, the period collapses, and the energy fades to weak. From the 16th through the 23rd, we’re looking at small, weak, choppy surf with energy often below 200 (weak). The 23rd sees a bit of cross-offshore wind, but the swell is only 2ft. It’s a long dry spell.

So, the call is simple: if you’ve got a board and a window, be on it Monday the 14th. That’s the one. Everything else is a flat, windy, or messy pass.

Rusty.
