The Lowdown
Alright, this is Rusty comin' at ya from the coast. Let’s break down what’s cookin’ at La Boca Con Con for the next couple weeks.
The first real action hits on Saturday morning, September 12th. We’ve got a clean southwesterly swell running at about 6 feet, with a short 8-second period, and a light south breeze keeping it cross-off. The combined energy is moderate, around 446, and it’s a good call for a beginner-friendly spot. But the real standout is Monday morning, the 14th. The swell drops a bit to 4 feet, but the period jumps to 15 seconds from the west-southwest, and with a glassy 5 km/h offshore from the south, the conditions are primo. The energy is strong at 882. This is the best session of the whole forecast – clean, long-period groundswell, uncrowded peaks, and the morning light to go with it. Just remember, with that long period, the waves might be a bit more lined up and better for a point or reef setup.
Tuesday the 15th morning is another solid option, with a clean 4-foot WSW swell, 13-second period, and a light SE offshore. Energy is still strong at 568.
The next standout window is Saturday morning the 19th. We’ve got a glassy 5-foot SW swell, 11-second period, and calm winds from the west-southwest. The energy is solid at 537, and this is a prime call for a fun, relaxed weekend session.
After that, Monday the 21st morning delivers a clean 5-foot SW swell with a 15 km/h SSE offshore. Conditions look good, energy at 366. Then Tuesday the 22nd morning sees the swell push up to 6 feet from the SW, 9-second period, with a light S cross-off. That’s getting into moderate size, good for most surfers, but the shorter period means more sectiony waves. Energy is strong at 566.
There’s a bit of a lull, but Friday the 18th morning offers a clean 3-foot WSW swell with a light SSE offshore – worth a look if you're hanging.
The second week is a mixed bag. Saturday the 26th morning has a glassy 3-foot W swell, and Sunday the 27th morning gives you a clean 4-foot WSW swell with a light S cross-off. Surfable, but nothing to write home about.
Bottom line: get out there Monday the 14th morning for the cleanest, longest-period groundswell of the whole run, and keep Saturday the 19th morning in mind for a glassy, fun session. The early window is your best bet.
Rusty.
