Petacalco is a powerful right-hander on the Mexican coast, breaking over sand. Its long, intense righthand barrels were once counted among the best surf on the planet, but expansion of the neighbouring port of Lázaro Cárdenas turned the wave into an ugly closeout. It has since risen from the ashes and is rideable again. Pollution is part of the picture here, drifting in from the rivermouth, the port, and nearby factories.
When It Works
Petacalco is always powerful, whatever the size, but the sandbar shape is crucial and close-outs are the rule. It draws swell from south through west-southwest to northwest (S-WSW-NW), with south swell the best match. It comes back to life on huge northwest swells, though a due south is where it really comes into its own. The wave works from 1.2 m / 4 ft to 3.7 m / 12 ft. Consistency can be patchy, so plan on catching it during the right windows rather than reliably.
Wind and Tide
Look for northwest offshore wind. It can work through low, mid, and high tide, with a rising tide generally the better call.
Local Tips
This is an expert's wave. The relentless power and the close-out tendency make it a serious paddle-out that rewards surfers who know what they are doing. Expect a moderately busy lineup when it's on.
