Why Seasonal Snorkeling in Cancun Is Special at Puerto Morelos
Seasonal Marine Life Events You Can Witness at Puerto Morelos Reef Park: Unlike crowded snorkeling spots, Puerto Morelos snorkeling takes place in calm, shallow waters protected by a natural reef barrier. This unique ecosystem allows marine life to thrive and follow natural seasonal cycles with minimal disturbance.
Because the reef is federally protected, guided snorkeling routes are designed to respect coral growth, breeding seasons, and migratory patterns. This makes snorkeling Riviera Maya not only exciting but also environmentally responsible.
Each season offers something different—here’s what you can expect throughout the year.
Winter Wonders: Sea Turtles and Clear Visibility (December – March)

During this season, snorkelers frequently spot:
- Green and hawksbill sea turtles feeding near coral gardens

- Eagle rays gliding along sandy patches
The calm sea conditions make winter ideal for beginners and families enjoying Puerto Morelos snorkeling for the first time.
