La Boca Concon is a reef break in Concon, Chile, that mostly breaks left.
La Boca Concon picks up swell from the SSW round to the W, and it's best when it's coming straight out of the SW. It starts working at around 1m and handles up to about 3m, with the sweet spot around 1.9 to 2.5m. Period matters too: aim for 16s or longer, as anything under 12s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
An E wind is dead offshore at La Boca Concon, and anything from the NE round to the SE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
La Boca Concon is at its best around the low to mid tide, roughly 0.5m to 1.5m on the local chart. Below 0.3m it gets dangerously shallow.
The most reliable run of swell at La Boca Concon comes Apr to Sep. There's a second window in Mar and Oct too. Needs solid swell. Best autumn to spring.
The water at La Boca Concon averages around 14°C, so you'll want a 4/3mm fullsuit. It shifts a few degrees through the year, so check the season before you pack.
It's more of an intermediate wave, rated 6/10 for difficulty, so newer surfers are best off sticking to the smaller days. Expect a moderate crowd (5/10) when it's on. River mouth can have pollution.
