Is September a good time to visit Cancun?

There are several advantages to visiting Cancun in September. During the low season, the beaches and attractions are quieter in Mexico and more relaxed. You're also likely to find more affordable deals on accommodation, flights, and excursions, making this period attractive to budget-minded travelers. Warm temperatures hold throughout September, providing ample opportunities for beach vacations and water activities.

However, the Atlantic hurricane season should be considered. While the risk of a direct hurricane strike is low, the potential for heavy rain and storms remains. This can affect outdoor event plans and lead to increased humidity.

The decision to travel to Cancun in September should be based on your ability to put up with possible weather disturbances. If you are comfortable with some unpredictability and are willing to adjust your itinerary, you can take advantage of the calmer atmosphere and cost savings.

Celebrate the Independence

Don't miss the opportunity to celebrate Mexico's Independence Day, held on September 16. On this day Cancun hosts parades, concerts, and colorful city fairs, and is a great opportunity to immerse yourself in Mexican culture.

Learn about Mayan heritage

Head to Chichen Itza to explore the Mayan ruins. You will be especially interested in visiting this place in September, as the Fall Equinox in Chichen Itza occurs around September 21 each year.

The equinoxes mark two moments in the year when the length of day and night are nearly equal. In Chichen Itza's main pyramid, El Castillo (also known as the Temple of Kukulkan), the architectural design is precisely calibrated and creates an impressive visual effect during the equinoxes. At sunset, the play of light and shadow creates the illusion of a snake slithering down the pyramid's staircase.
