Mexico's Pacific Coast spans four distinct sub-areas, from Puerto Vallarta in the north to Huatulco in the south, with Acapulco and Ixtapa and Zihuatanejo filling the middle stretch. The site mix runs from shallow protected coves and artificial reefs to open-water pinnacles, walls, caves and wrecks, giving every skill level something to work with. Reef fish are abundant throughout: the Guineafowl Puffer, Panamic Sergeant Major, Barberfish and Threebanded Butterflyfish appear at the great majority of sites, while the Spotted Eagle Ray is a reliable encounter across the coast. Conditions favour the cooler, calmer months from November through March and again in May.

Monthly water temperature across Pacific Coast's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperatures remain warm throughout the year, peaking in the summer and early autumn months and sitting slightly cooler from late autumn through spring. Visibility tends to be best in the drier months from November through March and in May, which also align with the peak season for diver visits. Summer brings warmer water but reduced visibility and more variable conditions at exposed sites.

Puerto Vallarta has the largest concentration of sites and is the base for operators such as Banderas Scuba Republic and Hurricane Divers, with notable spots including the cave and reef at Anegados in the Marietas Islands and the expert-level pinnacle site at Torrecillas. Huatulco offers reef and canyon diving including Whale Rock in Bahia San Agustin. Ixtapa and Zihuatanejo share a cluster of beginner-friendly bay sites, while Acapulco includes sites off Isla de la Roqueta such as La Marina and Palmitas.
Boat access is more common across the coast, particularly for reef, pinnacle and cave sites that sit offshore. Shore entry is available at a smaller number of sites, including Faro de Bucerias and Manzanillo, while several sites such as Playa Las Gatas and El Cristo offer both options. Checking the entry type for your chosen site in advance is worthwhile when planning with an operator.
