The Chimo area lies south of Puerto Vallarta along Mexico's Pacific coast, grouping five sites that include open reef, pinnacles, drop-offs, and an artificial reef. The namesake Chimo site features rock formations known as Las Iglesias rising from the seabed, suited to intermediate divers comfortable with strong currents and depths to thirty metres. Caletas offers shallower, beginner-friendly conditions with night diving, while Torrecillas is reserved for expert divers. Sea life recorded across the sites includes whale sharks, green and Ridley sea turtles, jewel morays, lesser two-spot octopus, Pacific cownose rays, and blue spiny lobster. All sites are reached by boat from Puerto Vallarta, though Playa Isabel at Yelapa also allows shore entry.
Monthly water temperature across Chimo's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water is at its coolest in spring, then rises steadily to peak warmth from July through October, when temperatures are consistently warm and visibility tends to improve. Conditions vary considerably between sites: Caletas runs mild currents while Chimo and Torrecillas can run strong, so site choice should match experience level. The warmer months generally offer the best overall diving conditions across the area.
