The Lowdown
Alright folks, Rusty here, looking at what’s on the cards for our local stretch.
Alright, let’s be honest, the next week and a half is looking pretty flat and ordinary for Playa de San Lorenzo. We’ve got a long stretch of small, weak surf with less-than-ideal winds for the most part. Don't get your hopes up for anything special until we get well into the second week.
We start off Monday the 10th with a tiny 2ft NW swell, period of 9 seconds. The morning is glassy, which is a nice thought, but the energy is weak (81). That combo doesn’t make for much more than a bump. It’s really just knee-high dribble. The afternoons then get chopped up by a cross-onshore breeze, so forget about it. This same story basically repeats through Tuesday the 11th, Wednesday the 12th, and Thursday the 13th. We get a little bump in period to 12 seconds on Thursday morning, which lifts the energy a bit (136), but the swell is still only 2ft. It’s a tease. Friday the 14th through to Monday the 17th is a write-off with poor conditions and onshore wind, and a few morning glass-offs that are too weak to care about. There’s a massive gap of days with absolutely nothing to recommend here.
Now, if you’re patient, things start looking up towards the end of the forecast. The first real standout arrives on Saturday the 22nd. The morning session is the one to target. We’ve got a clean 4ft swell from the NNW, with a solid 10-second period. The combined energy jumps up to a solid moderate 375. But the best part? The wind is glassy, coming light from the WNW. That is going to put a nice face on those waves. This is the best combination of size and clean conditions in the whole run. The swell direction is straight from the NNW, matching what this break likes to see. The afternoon does get a bit bumpy with a cross-onshore wind, so make sure you’re on it early.
Sunday the 23rd drops back down, with glassy conditions again but much smaller swell at 3ft to 3ft. It’ll be surfable but not worth getting too excited about after that Saturday morning session.
So there you go. A long flat spell, but that Saturday the 22nd morning is your window. It’s the only time the numbers really come together for a proper session. Keep an eye on it.
