Cozumel Temperatures Throughout the Year
Cozumel stays warm throughout the year. The main difference travelers
notice is not whether it is warm, but how much heat, humidity and rainfall
accompany the temperature.
Winter months generally feel more comfortable, while summer and early fall
can feel considerably hotter and more humid.
For specific monthly averages, use the individual month pages above rather
than relying on one annual temperature figure.
Rainfall in Cozumel
Cozumel has a tropical climate, so rain can occur at any time of year.
However, rainfall patterns vary considerably by season.
During wetter months, rain often occurs as showers or storms rather than
meaning that every day is completely rainy. Weather can change quickly,
so travelers should check the forecast close to their travel dates.
Hurricane Season in Cozumel
The Atlantic hurricane season officially runs from June 1 through
November 30. September and October are particularly important months for
travelers to monitor tropical weather conditions.
Hurricane season does not mean that a tropical storm or hurricane will
occur during every trip. It does mean travelers should understand the
increased possibility of tropical weather and remain flexible.

Sea Temperature and Water Activities
Ocean water around Cozumel remains warm enough for swimming, snorkeling
and diving throughout the year. Water temperature changes less dramatically
than air temperature.
However, temperature is only one part of the equation. Wind, waves,
currents, visibility and weather can affect water activities on any
particular day.
