The Lowdown
Alright, Rusty here again, breaking down the same window in feet and knots for the imperial crew.
We've got a bit of a slow burn at Playa de San Lorenzo. The first few days are tiny and messy, but there's a proper pulse of groundswell lined up for early next week that's worth marking your calendar for. The combined wave energy hits a strong 924 on Saturday morning the 5th, so there's some serious juice heading our way.
Water temp is 69°, right where it should be for this time of year.
Thursday and Friday are mostly bust. Friday morning the 4th offers a small 2-3ft NW swell, but it goes glassy with calm wind. It's clean but small—good for the log or a foil, but not a standout.
Saturday the 5th morning is where we see the first real swell: 5ft from the NW with a long 14-second period. That's some proper groundswell. The wind is cross-shore from the east at around 6 mph, so it's rideable but might have a bit of texture. This is the best option in the first week. The long period can make it a bit walled at a beach break, but plenty of energy to work with.
Sunday the 6th still has some size, 4ft from the NNW, but the wind flips to a light cross-onshore from the NW, so not as clean.
Now, Monday the 7th morning is the real standout. Swell holds at 4-5ft from the NW, period at 12 seconds, with a combined energy of 560. The wind is only 3 mph from the NW and it's glassy. That’s the best forecast of the whole run: clean, powerful groundswell at a manageable size. That's a session to plan around.
After that, things drop off. Wednesday the 9th morning is worth a look with 4-5ft NNW swell and glassy conditions from calm winds, but the period drops to 9 seconds so it's a little weaker.
The second week is mostly flat and choppy. There's a bump of 7ft N swell on Wednesday the 16th, but it's only 8 seconds of period with a messy cross wind. That one looks more like a kite-surfing day than a paddling day.
The rest of the fortnight drops off to tiny, onshore slop. Not much to chase.
Your two windows: Saturday morning the 5th for the first taste of size, and Monday morning the 7th for the cleanest, best shaped waves of the whole outlook.
Keep your eye on the horizon,
Rusty
