The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for La Boca Con Con over the next couple of weeks.
There’s a bit of a slow start to this forecast period, but hang tight – it builds into some serious size later in the first week. The overall pattern is one of small, clean glassy conditions early on, then a solid pulse of WSW groundswell mid-week that could get a bit too big and gnarly for the average punter. The water’s sitting at 57°F right now, which is pretty much average for the time of year, nothing out of the ordinary.
We kick off Tuesday morning, the 25th of August, with some small cross-on swell in the 2ft range from the WSW, period 15 seconds – that’s a long period groundswell but the energy is weak (237) and the wind is on it. Not worth paddling out for. Tuesday afternoon looks a little bigger at 3ft but still cross-on and marginal. A gap day.
Wednesday the 26th is where it starts to get interesting. Wednesday morning we’ve got glassy conditions, a 5ft WSW swell with a 12 second period, and the energy is ramping up (641). This is a good, clean, manageable wave for the intermediate surfer. Wednesday afternoon gets even better: 6ft, still WSW, 12 seconds, and the wind goes cross-off, giving us very clean surf. The energy jumps to 907. This is the standout of the first part of the week – clean, solid, and the wind is your friend.
Now, Thursday the 27th – buckle up. The swell jumps to 12ft from the WSW, 14 second period, energy through the roof (4822 in the morning, 4346 in the afternoon). This is big, powerful groundswell. For a beach break like La Boca Con Con, this is going to be a washing machine. The wind is straight onshore in the morning and cross-on in the afternoon, and the forecast notes marginal conditions. This is expert territory only, and honestly, it’s looking more like a kite-surfing day than a paddle-surfing day. The wave quality is compromised by the sheer size and the wind. Friday the 28th isn’t much better – still 8ft and 8ft, cross-on winds, energy still high (2188 and 2003). The swell is too big and the conditions are not clean. A skip for most.
Saturday the 29th drops back to 6ft and 6ft, but the wind is cross-shore, not glassy or offshore, and it’s still marginal. Not the best.
Sunday the 30th is a write-off – 5ft from the NNW, cross-on, choppy, poor conditions. No good.
Then we get a nice little window. Monday the 31st of August: morning brings 6ft from the SW at 12 seconds, cross-off wind, clean, energy of 1090. This is a very good session, solid overhead, clean face. The wind is offshore, so the waves will be holding up nicely. Again, this is a strong option. The afternoon picks up a bit more wind (12 mph) but still cross-off, so it’s still rideable.
Tuesday the 1st of September, the swell drops back to 6ft and 5ft, cross and cross-off wind, but the energy is dropping (765 and 578). It’s still surfable, but not a standout.
Wednesday the 2nd of September morning has a tiny 2ft swell with a very long 18 second period. That’s a long period groundswell, but it’s barely a ripple. The afternoon jumps back to 6ft from the SW, 10 seconds, but with a 16 mph cross-off wind making it choppy. Not great.
The real stand-out for the whole forecast, in my opinion, is Friday the 4th of September. You’ve got the morning with 4ft from the SW, 11 seconds, and offshore wind from the SE. Light, clean, perfect. Then the afternoon is glassy, 5ft from the WSW, 13 seconds, energy of 839, and the wind is calm – flat calm. That’s a dream session. Clean, glassy, head-high, and no wind to mess it up. That’s the one to circle on the calendar. Crowds are listed as “sometimes” at this break, so you might have company, but glassy conditions and a good swell make it worth the crowd.
Saturday the 5th of September sees a 7ft pulse from the WSW, 14 seconds, but the wind is onshore and cross-on, so it’s not as clean. The energy is high (2040), but the wind is the enemy.
The rest of the second week trails off into smaller, weaker swells (2ft to 3ft) with glassy periods, but nothing to get excited about. The energy is all under 500. It’s a nice end to the run for a longboard or a beginner session, but not a standout.
Rusty out.
