The Lowdown
Alright, let’s talk in feet and miles per hour. Straight up, the El Sardinero - Primera scene is looking weak for the first week. The water is about average temp for this time of year, nothing weird. The swell energy is mostly in the double digits, which is just weak, and the direction is all over the place, not hitting this spot's sweet spot from the north.
From Sunday the 16th through Wednesday the 19th, it’s all "poor surf conditions" with tiny waves under 3 feet and short periods. The wind is mostly onshore or side-shore, making it a mess. There’s a glassy moment on Monday the 17th morning, but the swell is just 2 feet with a 6-second period – not happening.
Thursday morning the 20th is a small bright spot. Glassy calm, and a 2-foot swell from the NNW, but the period jumps to 11 seconds. That’s a long period, and with no wind, it might give a clean, tiny wave for the patient. The combined energy is 111, so there’s a bit of push, but it’s still very ordinary.
The next best look is Saturday the 22nd morning. Glassy conditions again with a 3-foot swell from the NNW at a 9-second period. The combined energy is 150, so it’s got a bit more weight. This is the best-looking morning of the first week, but it’s still just okay.
The 23rd to the 28th is a rough stretch. Onshore, side-shore, and messy winds kill any chance of good surf. The energy drops back into the double digits.
For the end of the month, we get a pulse. Saturday the 29th morning brings a clean, cross-offshore wind from the west with a 3-foot swell from the NW at a 10-second period. The combined energy is 157, which is moderate. That’s a decent session.
But the real winner is Sunday the 30th morning. The wind turns offshore from the WSW, light at 5 km/h, with a 4-foot swell from the NW and a 10-second period. The combined energy is 323, which is a solid, moderate wave. This is the one to target. It’s clean, has some punch, and the direction is right. Expect crowds, as this spot is often busy, but for a wave like that, it’s worth the company.
The 30th morning is your best bet. The rest is a waiting game.
Rusty.
