The Lowdown
Alright folks, Rusty here. Let's break down La Boca Con Con for the next couple of weeks.
The overall picture is mixed, with a couple of decent windows that'll get a few heads out, especially if you pick the right time.
Wednesday August 12th kicks things off small. We're looking at 1 to 3 ft waves from the WSW with a super-long 18-19 second period. The morning and afternoon are both glassy with light winds. Water temp is about 57°, which is normal for this time of year (about 2° warmer than usual, nothing crazy). Combined energy is weak to moderate (281, then 479). Clean but tiny.
Thursday August 13th sees a bump to 4 ft in the morning and 4 ft in the afternoon, but onshore winds from the NW and NNW mess it up. The period drops to 15-16 seconds, but the energy picks up (805 then 572) – moderate, punchy swell. Not worth it with the wind.
Friday August 14th starts cloudy and cross-onshore with 3 ft waves. Skip it. But Friday afternoon is a winner – the wind goes glassy, and we get a clean 5 ft pulse from the WNW with a shorter 9-second period. Combined energy of 561 (moderate). That’s a fun, clean little wave for a sunset paddle.
Saturday August 15th is a mess in the morning with rain and messy winds. The afternoon sees only 3 ft with a cross-shore wind. Not your day.
Sunday August 16th has a solid morning window: 3 ft from the WSW, 14-second period, and clean cross-off winds from the south. Combined energy of 410. That’s workable. The afternoon gets blown out by strong SSW winds, so be there early.
Monday August 17th starts a better run. The morning brings 5 ft from the SW, but only an 8-second period. The energy is moderate (650), with clean light winds. The afternoon jumps to 6 ft from the SW, still short period (8 seconds), with a light cross-onshore wind. It’s rideable for the size, but that short period makes it a bit wonky.
Now, Wednesday August 19th is the standout. The morning session is a gem: 6 ft from the WSW with a long 16-second period, giving a combined energy of 1555 – that’s strong. The wind is glassy. This is a proper groundswell with excellent shape and clean conditions. At 6 ft and that long period, it’s a bit much for beginners, and it might break a bit straight at a beach break. For experienced surfers, it’s the one to circle.
Thursday August 20th and Friday August 21st continue the swell, with 5 ft to 7 ft from the SW and WSW, with period dropping from 13 to 9 seconds. Winds are mostly clean and cross-off, so there’ll be waves, but the quality isn’t as high as Wednesday morning. By Friday afternoon we're at 7 ft, which is expert territory.
The following weekend (August 22-23) drops off hard: 4 ft to 5 ft with poor to ordinary conditions and onshore winds. Stay home.
Monday August 24th to Wednesday August 26th stays small (2 ft to 3 ft) and fairly poor, though Tuesday August 25th morning has glassy conditions on 2 ft from the SW with an 11-second period – tiny but clean for a longboard.
The final day, Thursday August 27th, offers a glassy afternoon with 3 ft from the WSW and a 14-second period. Combined energy is weak (367), but a clean little wave to end the run.
Overall, the best bet is Wednesday August 19th morning – that 6 ft, glassy, long-period groundswell is the clear highlight. Second best is Friday August 14th afternoon for a glassy, fun-size wave.
Rusty out.
