The Socorro Islands offer the best big fish diving in Mexico’s waters. The islands can only be visited between November and May, because of its exposed location. The approximately 28 hour journey is rewarded by many shark species, including large schools of hammerhead sharks, manta rays, and the great Pacific occurs regularly in the islands. At a cleaning station at San Benedicto can observe the mantas at close. From February to April, you can see humpback whales. All dive sites offer interesting underwater structures, ranging in greater depths down, but the vegetation is fairly sparse.
The dive sites of the Sea of Cortez do not impress with most colourful coral reefs, but with great abundance of fish. Dive sites such as Los Islotes with its colony of sea lions are a highlight for every diver. If you are very lucky, you may see hammerhead sharks at the El Bajo Seamount.
The watertempertures in the Sea of Cortez and Socorro are between 19°C (66° F) in January and 28°C (82°F) in October. A 7mm wetsuit with hood is highly recommended during the cooler months. For the cave diving in the Yucatan the water temperatue is year-round at pleasant 24°C (75° F).
