Las Piscinas Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day window on the cards for Las Piscinas, but I’m not gonna lie to you – it’s a rough stretch. The whole run is plagued by onshore and cross-onshore winds, and the wave quality is consistently poor. The swell is there, but it’s a messy, short-period windswell that’s just not going to line up properly. There’s no standout session, nothing you’d rush out of bed for. The combined swell energy ticks up and down, hitting moderate to strong levels (116 to 857), but it’s all badly directed and wind-affected. The first real glimmer of something different doesn’t come until the very end of the period, and even that’s marginal.

Starting Saturday the 5th of September, we’ve got a NNE swell pushing 4ft but with a rubbish 5-second period and a stiff northerly breeze. Combined energy is weak at 116, and it’s just not worth a paddle. That sets the tone for the whole first week. The water temperature is a touch warmer than normal at 76°, but that’s the only good news. The swell builds through Sunday the 6th and into Monday the 7th, hitting 5ft to 6ft, but the period stays short (6-7 seconds) and the wind stays onshore. The energy jumps to moderate (254 to 438), but it’s all junk. Tuesday the 8th and Wednesday the 9th are more of the same, with the wind turning cross-onshore and the waves turning choppy. The swell holds around 5ft to 6ft, and the energy is moderate (364 to 439), but it’s a frustrating, bumpy mess.

The second week doesn’t offer any relief. From Thursday the 10th through to Tuesday the 15th, the swell slowly drops from 6ft down to 2ft, with the wind staying onshore or cross-onshore. The period is still short (7-8 seconds), and the combined energy drops from moderate (267) down to weak (129). The best you can say is that the wind does ease at times, but it’s never clean. Wednesday the 16th of September is the only day that raises an eyebrow. The swell drops to 2ft–3ft, but the period jumps to 14 seconds from the NW, and the combined energy spikes to 329–442. It’s a long-period groundswell, which is a big deal for a reef break like this, and it’s coming from the north-west, which is cross-onshore for the optimum N direction. The wind is light, but it’s still cross-onshore, so it’s only a marginal, questionable session. This is the only thing even close to a standout, but it’s a gamble.

Then we get a final pulse starting Thursday the 17th of September. The swell jumps back up to 7ft from the NNE, with a period of 8 seconds and a strong onshore wind. The combined energy hits 789–857, which is strong. But the wind is onshore, the period is short, and the quality is still poor. This is not a session for learning; 7ft with onshore wind at a reef is for experienced surfers only, and even then, it’s going to be a battle. The swell drops through Friday the 18th and into the weekend, finishing with 3ft on Sunday the 20th.

So, to be honest, there’s nothing here to get excited about. The whole 16 days is a washout. If you’re desperate, keep an eye on Wednesday the 16th for that long-period NW groundswell, but keep your expectations low. The wind is just never your friend here.

Rusty.
