Las Piscinas Surf Forecast and Surf Report

G’day, Rusty here. Let’s be straight with ya—this Las Piscinas stretch is in for a pretty flat and windy run for most of the next couple of weeks. The surf’s been on the small side and the wind’s been howling out of the north and north-northeast, so it’s been a whole lot of choppy, bumpy conditions. Water temp’s sitting at a normal 75°, nothing to write home about.

We kick off Wednesday the 9th of September with a 5ft swell from the north-northeast, but that 12 mph cross-onshore breeze is just messing it up. Surf quality is poor, wave energy is weak (278), and it’s a write-off. That same story runs through Thursday and into Friday—north winds at 12-15 mph, swell hovering around 5-5ft, but still cross-onshore or onshore, and the period’s a short 7 seconds. Not a single ride worth paddling for.

Saturday the 12th bumps up a touch to 6ft, and wave energy gets into the moderate zone (470), but the onshore wind at 15 mph is still ruining it. Sunday’s similar—5ft at 8 seconds but onshore wind keeps it messy. The surf quality is poor, and I’m calling it a bust.

Then comes Monday the 14th—this is where we get a little window. Monday morning, the wind swings light and offshore from the south-southwest at 3 mph. Swell drops to 4ft from the north-northeast, 8-second period, and the wave energy is moderate (305). Conditions clean right up. By Monday afternoon it goes glassy: 2ft from the north-northwest, but a very long 12-second period. That’s clean, but tiny—more of a longboard glide than a proper session. Wave energy is moderate (272).

After that, from Tuesday the 15th, we drop back into rubbish. Sideshore or onshore winds, swell staying 2-3ft through Wednesday, and weak energy (109-186). Nothing doing.

Thursday the 17th to Saturday the 19th sees a rise to 5-6ft from the north-northeast, but onshore winds at 9-15 mph and short 7-8 second period keep it a choppy mess. Wave energy climbs to moderate-strong (356-488), but it’s not surfable.

Sunday the 20th has a 6ft north-northeast swell, light cross-onshore wind, and moderate energy (416)—still poor surf quality.

Now look, the 21st of September brings something interesting but tricky. A very long-period 17-second groundswell from the north-northwest rolls in at 3-3ft. Wave energy surges to strong (814-861). But the wind is cross-onshore at 9 mph, so it’s choppy. This is a reef break, so that long period could actually line up nicely here, but the onshore wind will chop it up. It’s only marginal—good for an expert who knows the reef, but not a standout for most.

The 22nd and 23rd keep that long-period swell (11-13 seconds), 3-4ft, but the cross-onshore breeze stays, and wave energy drops to moderate (299-528). Still not worth a mission.

The standout: Honestly, the best on offer is Monday the 14th of September. Monday morning is your call: clean offshore wind, 4ft north-northeast swell, 8-second period. It’s small but tidy. Monday afternoon goes glassy with 2ft, very long period—great for a mellow session if you’ve got a log. There’s nothing else in this 16-day window that’s clean and has any size. For the rest, it’s blown-out, onshore junk.

Be warned: this is a consistent reef break that’s exposed to the north, and when the wind’s on it, it’s just no fun. The moderate wave energy periods (100-500) are all paired with bad wind. The strong energy days (500+) have cross-onshore wind, so more for the kite crew than paddle surfers.

Rusty signing off.
