The best time to visit Cozumel is from March to June, when the weather is warm, the skies are mostly clear, and the island is less crowded than during peak winter months. During this period, you’ll enjoy ideal snorkeling and diving conditions with great underwater visibility. If you’re looking for fewer tourists and lower prices, late spring offers a perfect balance. Avoid hurricane season (August to October), as heavy rains and storms may affect your trip. Cozumel’s charm is year-round, but timing your visit right makes it truly unforgettable.
