Key Dive Site Facts
Dive Site Overview
Formed by ancient geological processes, El Morro stands as a remote volcanic outcropping, distinguishing itself with dramatic rock pinnacles that break the ocean's surface. These formations extend deep below, creating a labyrinth of caves, tunnels, and walls within the northern edge of Banderas Bay, considered part of the protected Islas Marietas area.
Dive excursions typically involve a two-tank trip, often pairing El Morro as the primary, deeper dive with the shallower Los Anegados for the second. Departing from Punta de Mita, the boat ride to El Morro usually takes about 30 minutes, or longer if from Puerto Vallarta (around 95 minutes). Navigating the shallow entrance to the cave (around 9 meters deep) and its 15 m (50 ft) tunnel reveals granite walls adorned with marine life, showcasing the site's rich ecosystem.
Los Anegados, a nearby rocky bank with intricate volcanic formations, complements the experience by offering shallower sections that gradually deepen, providing additional exploration opportunities for diverse creatures.
Best Time to Dive
For optimal diving at El Morro, consider visiting during the months of January through May, and again from July through September, and November to December, which consistently report a "Good" dive score. During these periods, average air temperatures range from 22.9°C (73°F) in March to 29.0°C (84°F) in August, offering comfortable surface conditions. Rainfall is minimal from January to May, often registering less than 0.5 mm, ensuring clearer skies. While water temperatures are not consistently reported for every month, available data indicates a range from 17-28°C (62-82°F), suggesting warmer waters are more likely during summer and early fall. Wave heights generally remain around 1.1-1.4 meters year-round, and wind speeds hover around 20-23 km/h. Months like June, August, and October may see a "Moderate" dive score due to slightly increased rainfall (up to 5.3 mm in September) or other variable factors, but still offer viable diving.
