What’s the weather like in Cancun in May?

Cancún has a tropical climate with hot weather all year round, and that’s due to its location in Mexico on the  Caribbean coast. If you’re going in May, you can expect high temperatures, although it’s the start of the wet season. This is from May to October but you’ll see much less rain in May compared to the wettest months of the year, September and October. It doesn’t usually rain for long however, and you’ll still get plenty of clear skies and sun.


The average high in Cancún is 33ºC in May, and it only cools to 22ºC at night so you don’t need to bring many warm clothes with you. At 27ºC, the sea is perfect for swimming, while humidity’s very high. There’s 109mm of rain over seven days, and you can expect 13 hours of daylight with eight hours of sunshine each day. UV levels will be extremely high so pack plenty of sun cream. The sun goes down at around 7.20pm.
