The Lowdown

Alright, Rusty here. Let’s take a hard look at what’s on the table for Playa de San Lorenzo over the next couple of weeks. We’ve got a slow start, but there are some real moments of magic to circle on your calendar if you’re patient.

Right now, the water temperature is sitting at 70°, which is a touch warmer than normal for this time of year, so you might not need the thickest rubber just yet.

The first week kicks off with a bit of a whimper. Saturday the 12th is a write-off with a tiny 2ft NW swell, weak energy (130), and a cross-onshore wind making things choppy. Not worth getting wet.

But things turn around fast. Sunday morning, September 13th is your first real standout. We’ve got a clean 5ft NW groundswell, with a 12-second period, packing moderate to strong energy (624). The wind is light and cross-offshore, so the faces will be clean. This is a solid wave, but still approachable for an intermediate. The break is fairly exposed and the optimum direction is NW, so it’s lining up well.

The next few days are a mixed bag, with some smaller surf and choppy afternoons. Wednesday the 16th morning benefits from glassy conditions, giving you a clean 5ft NNW swell, but with a short 8-second period – it’ll be a bit crumbly and soft. Thursday the 17th morning is a better bet: glassy again, 6ft NNW swell at a better 10-second period, and strong wave energy (795). That’s the best of the first week.

But the real highlight, the one you wait for, is Monday the 21st of September in the morning. This is the best of the entire outlook. A solid 7ft NNW swell from the northwest, with a long 14-second period pushing serious energy (1560) towards the beach. It’s clean, with a light cross-offshore breeze. This is expert territory, as the swell hits over 8ft in the afternoon, so the morning session is your window if you’ve got the skills. The break is fairly exposed and the swell direction matches the optimum perfectly. This is a day to call in sick.

After that, the surf backs off through the final week, with dropping heights and a return to smaller, less consistent conditions. The very last day, September 27, sees a long-period 5ft NW swell (16-second period, 1429 energy) but with onshore wind and light rain, so it’s more of a hope than a plan.

This break is consistent and fairly exposed, so it usually has something, but the real gold is that Monday the 21st. Don’t sleep on it.

Rusty.

A general guide to surfing at Playa de San Lorenzo can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Playa de San Lorenzo may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
