Isla Mujeres enjoys a tropical climate with warm temperatures year-round, averaging between 75°F and 90°F (24°C–32°C). The island experiences two main seasons:
- Dry season (December to April): Warm, sunny, and perfect for swimming, snorkeling, and sightseeing. This is the best time to visit the island, if you’re okay with it being more crowded.
- Wet season (May to October): Hotter, more humid, with occasional tropical showers and fewer crowds. The rains can impact your plans to go snorkeling as well.
