Cozumel is one of the most visited cruise destinations in the world, and for good reason. The island sits in the heart of the Mesoamerican Barrier Reef — the second-largest coral reef system on Earth — making it a snorkeling and diving paradise. Beyond the water, visitors enjoy colorful San Miguel town, Mayan ruins, and white-sand beach clubs.
Cozumel in May is warm and sunny, with average highs around 89°F and lows that rarely dip below 76°F. Expect around 7 rainy days, typically brief afternoon showers rather than all-day rain. Morning excursions are usually the safest bet. Heat builds, occasional showers
Crowds are moderate in May, making it a good balance between availability and weather. Pack reef-safe SPF 50+ sunscreen, a hat, and breathable fabrics — the sun at 89°F is intense, especially near the water.
