The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s brewing for La Boca Con Con over the next couple of weeks.
Straight up, this is a run with a lot of onshore wind, and most of the time the surf is just okay, not pumping. The best sessions are going to be when the wind drops, turning things glassy. There’s a potential standout right at the end of the first week and another one a bit further out, but you’ll need to be patient.
The first notable surf kicks off on Saturday, September 5th in the morning. We’ve got a solid SW swell pushing 6 ft, with a period of 9 seconds. The wind is a light cross-offshore from the SSW at 6 mph, and the wave energy is strong (1199). The description says "very good surf conditions," and for a beginner-friendly spot, this is a solid window. The water temp is about average for this time of year, so no need for a thick suit.
Saturday afternoon drops off to 3 ft, but the period jumps to a very long 18 seconds. That’s a groundswell, and at a beach break like La Boca Con Con, it can get a bit straight and harder to read. The wind picks up a little, too. It’s not the best window.
Sunday, September 6th through to Thursday, September 10th is a stretch of light cross-onshore winds and smaller, less powerful swells. The waves are there, but it’s a bit messy—marginal at best. The combined energy drops from 1200 down to around 429 by Thursday morning. It’s surfable, but not worth getting excited about.
Thursday afternoon on September 10th brings a spike in swell size to 6 ft, but the period drops to a short, weak 7 seconds. The wind turns cross-offshore from the SSW at 12 mph, which cleans it up, but the short period means it’ll be a bit jumbled.
The first real standout is Friday, September 11th, in the afternoon. The wind is cross-offshore from the SSW at 9 mph, producing clean conditions. The swell is 5 ft from the SW with an 8-second period, and the energy is moderate (618). It’s described as "good surf conditions," and with the beginner-friendly consistency and a light offshore, this is the pick of the first week.
Saturday, September 12th and Sunday, September 13th have a mix. Sunday afternoon on September 13th is a gem: glassy conditions with a light SSE breeze, a 3 ft SW swell at a very long 15 seconds, and strong energy (704). The description says "very good surf conditions." That long period at a beach break means it might be a bit walled, but glassy is glassy, and it’s a great window for a log or a mid-length.
Monday, September 14th and Tuesday, September 15th are back to light cross-onshore winds and smaller swells. But Tuesday afternoon, September 15th, is another glassy session: a WNW breeze at 3 mph, 4 ft swell from the WSW at 12 seconds, and moderate energy (690). "Very good surf conditions" again. That’s a solid runner-up.
From Wednesday, September 16th onward, the swell drops off. The mornings are small, but the afternoons go glassy on the 16th and 17th, offering a few clean but weak waves. The last real pulse is Saturday, September 19th, with a 6 ft to 6 ft swell from the WSW, but the wind is onshore or cross-onshore, making it a messy, difficult prospect. For a beginner spot, that’s too big and blown out.
Honestly, the standout for the whole period is Friday afternoon, September 11th—clean, cross-offshore wind, decent size, and good energy. The glassy session on Sunday afternoon, September 13th is a close second for the cleaner conditions. The second week (after September 16th) is thin, with only a few glassy but weak windows.
Rusty.
