However, with factors to consider, such as humidity, rain, temperature, and the likelihood of seeing sea creatures, you might wonder when is the best time to go. 

In this article, we’ll take a closer look at these factors and provide a recommended time frame for visiting Isla Mujeres to make the most of your trip. 

Whether you’re interested in snorkeling with whale sharks, watching sea turtles nest and hatch, or simply soaking up the sun, this guide will provide valuable information to help plan your perfect getaway.

The Overall Best Time to Visit Isla Mujeres

The best time to visit Isla Mujeres is from late November to February. These months have lower humidity, less rain, mild temperatures, and an increased chance of seeing turtle hatchings and whale sharks. 

Humidity is Best from December to February

The humidity levels in Isla Mujeres fluctuate throughout the year and are affected by the wind, rain, and temperature. 

The most comfortable humidity levels are in the winter, from December to February. During this time, the average humidity levels range from 60%-70%. 

The highest humidity levels, and thus most uncomfortable, happen during the summer months, from June to September. During this time, the average humidity can reach over 80% due to high temperatures and high moisture levels in the air. 

Visiting Isla Mujeres during times of low humidity offers several advantages:

  • Better air quality: Lower humidity reduces mold growth and other allergens.
  • Easier to stay active: Lower humidity makes it easier to engage in outdoor activities without feeling weighed down by the heat and moisture.
  • Improved sleep: Especially in air-conditioned rooms.
  • Better for certain health conditions: People with asthma and allergies often feel better in a low-humidity environment.

There is Less Rain from December to May

Isla Mujeres is best enjoyed outside, particularly on the beach, so you want to go when the rain doesn’t keep you indoors.

The rainy season is from June to October, with the highest rainfall in September and October. During these months, there are often heavy downpours and thunderstorms.

Visiting during the dry season offers the best experience on the island:

  • The dry season offers sunny skies and lower humidity, making outdoor activities more comfortable.
  • Reduced risk of hurricanes: as an area prone to hurricanes, the dry season gives you the best chance to avoid them.
  • The clear waters of the Caribbean during this time are ideal for snorkeling, diving, and other water activities.
  • More options for tours, dining, and other activities because the dry season is also the peak tourist season.

Whale sharks are the largest fish species in the world. They come to the island’s waters to feed on plankton, making it a popular time for snorkeling and diving excursions.
