The storm risk#
Most years, stormy days at worst. Some years, a hurricane or tropical storm close enough to shut the airport and the beaches for several days. Insure for weather, book refundably, watch the forecast. A trip that can move is a good bet; a wedding is not. Hurricane season explained.
What's on#
Independence Day: the Grito at Parque de las Palapas downtown on the night of the 15th, a holiday on the 16th. The one night of the year to be downtown, not in the hotel zone. Mexico City's version is the national stage.
Prices and crowds#
The floor; resorts nearly empty, some closed for maintenance, upgrades common. On a budget.
What to do#
The sea is warm and usually clear: Isla Mujeres, snorkelling at Puerto Morelos, cenotes, the ruins to yourself (day trips). Rainy afternoons: a spa, a long lunch, the museums. Things to do, 3 days.
Pack#
Light clothes, a real rain layer, bug spray, a book. First time in Cancún.
Someone on the ground#
A local's forecast beats an app's in September. Post your dates on Roavi Community and Local Friends who live in Cancún tell you how the week looks and where the Grito is. One evening with one in the quietest month is the city with the volume down.
