Cancun weather in May is less rainy than other months, and temperatures are usually quite hot.

Two key events make May a popular month to visit. The Cinco De Mayo festival takes place on May 5th, and the famous Cancun Jazz Festival takes place every year in May.

Average Rainfall

It has a wet and dry season. The Caribbean hurricane season runs from June to November, but Cancun receives most of that rain during September and October.

The region is known for getting bad weather and a lot of rain during the autumn months.

The time of year with the least amount of rainfall is February through May. 

Rain is expected seven days during the month. Cancun receives on average about 3.4 inches during the month.

The rain tends to occur in the form of a sporadic, heavy shower that rarely lasts for more than a few minutes in duration.

It is important to note that, rain or shine, the UV index in May is very extreme at 11+. Visitors will want to have sunscreen close by.
