    Cancún has a tropical climate with high temperatures all year round and a distinct rainy season. The dry season’s from November to April, while the wet season’s May to October. September gets more rain than any other month, although it often comes in short sharp downpours.


    The average high in Cancún during September’s 33ºC, so it’s nice and warm. It doesn't get much cooler at night, with temperatures only falling to 23ºC, so you don't need to bring many warm clothes for the evenings.
