Acapulco is filled with a wide variety of interesting dive sites, all of which take less than 30 minutes to reach by boat. Choices include sunken ships, walls, pass through rock formations or the acclaimed Sea Mountain, whose depth ranges from 15 feet at its peak down to 150 feet. There are also more than 10 dive sites clustered around a local island.
The diving changes by season, but sea life is always plentiful. You'll see sandy and rocky bottom composition with small coral formations, sea fans, barnacles, gorgonians, sea stars, trumpet fish, jacks, schools of mackerel, sea horses, and, on occasion, sea turtles, eagle rays, whale sharks, and manta rays.
November through February is the best time if year to dive in Acapulco, with 50 feet average visibility and water temperatures that generally range from 82 - 86 degrees Fahrenheit. The waters cool down from March - May, with average temperatures of 65 - 75 degrees Fahrenheit. Plankton during these months tends to reduce the visibility but adds the possibility of seeing whales and dolphins on your dive. The water warms up to around 85 degrees Fahrenheit from June through October with visibility generally very good but dependent on local rain activity.
