Frequently Asked Questions

What kind of wave is Constitucion?

Constitucion is a beach break in Maule Region, Chile, with peaks that run both left and right.

What swell works best at Constitucion?

Constitucion 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 0.8m and handles up to about 3m, with the sweet spot around 1.8 to 2.5m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.

What wind is offshore at Constitucion?

An E wind is dead offshore at Constitucion, 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.
