Averaged from the last five years of September readings — a guide to what to expect, not a forecast for a particular sailing.
Cozumel is one of the most visited cruise destinations in the world. The island sits on the Mesoamerican Barrier Reef, the second-largest coral reef system on Earth, which is what keeps snorkelers and divers coming back. Away from the water there is the town of San Miguel, the Mayan ruins at San Gervasio, and white-sand beach clubs.
Cozumel in September is warm and sunny, with average highs around 90°F and lows that rarely dip below 77°F. September sees roughly 16 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Wettest month, hurricane season
It's the shoulder season in Cozumel: fewer crowds than the winter peak, but the heat and humidity are at their highest. A light rain jacket and early-morning excursions will serve you well. Pack reef-safe SPF 50+ sunscreen, a hat, and breathable fabrics. The sun at 90°F is intense, especially near the water.
