July in Cancun

Cancun in July is an average kind of month occupancy wise. At the start of the month there may be groups of younger students from the US enjoying what is known as ‘summer break’, although summer break in Cancun no longer attracts the kind of numbers it once did.

Once school is out then Cancun becomes a popular destination for families not only from the US, Canada and Europe but also National tourists from other parts of Mexico. Cancun hotel prices in July are generally a little higher than June, but a little lower than in August.

As for recommended tours, you’ll have no problem finding something to do in July, with water based activities being the sure fire winner in this hot and sweaty month. A great little tour to do at this time of year would be an Isla Mujeres catamaran tour.

A trip to the ruins may be inadvisable due to the extreme heat inland at places like Chichen Itza and Coba unless you are real sun worshiper. Wherever you go be sure to keep yourself hydrated take something to cover your head and apply plenty of sun screen.
