Cancun Weather - Best and Worst Months to Go

Cancun weather is one reason why this Mexican resort enclave is the second most popular vacation destination in the Caribbean region.

Other reasons why Cancun draws so many tourists include its hotel, shopping and restaurant strip; the inexpensive bus transportation system; plenty of things to do; and convenient access to and from U.S. airports. It is 1.5 hours flight time from Miami and four hours from Chicago.

The best time to go to Cancun depends in part on whether you prefer to spend a lot of time on the beach and in the water, or if you like to spend most of your time shopping, dining and visiting the various attractions in the region. Some fabulous Mayan ruins are located nearby.

Cancun weather is generally warm throughout the year -- in fact many hotels and resorts have open air lobbies -- but offshore breezes can make the air and water more chilly in winter months.
