The Lowdown
Alright folks, Rusty here. Let’s break down what’s in the water for Playa de San Lorenzo. It’s a slow start, with a long stretch of nothing to get excited about for days. The real action waits until the second week.
The water temperature is about 71°, which is a touch warmer than usual – feels good on the skin, about a degree and a half above the norm.
The first proper, glassy shot comes on the morning of Thursday, August 29th. Calm winds, a 5ft swell from the NW at 8 seconds, and moderate energy. Not big, but clean enough to enjoy. The morning of Monday, September 1st is similar: a 5ft NW swell, 10-second period, solid energy, and glassy conditions – a solid, clean morning.
But the one you really want to look at, if you know what you’re doing, is the morning of Tuesday, September 8th. This is the standout. A very long-period groundswell from the NW, pushing 10ft at 14 seconds, with massive energy. That’s a proper, heavy pulse. That size is for experts only. The wind is a light cross-onshore from the ENE, and for a beach break, that long period might make the waves run straight, begging for a point or a reef setup. The power is unreal.
The morning of Wednesday, September 9th brings a nice clean-up: glassy conditions with a 5ft swell from the NNW at 8 seconds. A solid day for getting back out there.
For most of this stretch, expect onshore winds, small weak swell, or just junk conditions. Don’t bother paddling out early. Patience is key.
This is Rusty, out.
