The average annual temperature of the Riviera Maya is 78^oF, with fluctuations of 5 to 7 degrees.

In June, July, and August, visitors can expect hot and sunny summer wheather with occasional rainfall. Usually when it rains it rains hard for a little while then dries up quickly. This is also when the sea is the calmest.

The hurricane season runs September through December and the sky can change from clear to overcast in minutes. The ocean water is warmest August-September and starts to cool down in November.

July through September the temperature is highest, as is rainfall. This is also the mosquito season.

November, December and January are the coolest months here, which means it's very comfortable. There might be some rain, but not daily. This time of year, nights can be much cooler and a jacket required.

Spring (February to May) is a beautiful time of year on the Riviera, with very little rain and flowers everywhere. The ocean gets calmer and warmer, as temperatures rise. Nights can still be a little cool but the temperature is milder and more comfortable.

All year round the humidity level is very high, often around 90 percent. Regardless of what time of year you get here, you will have great beach days and not-so-great beach days, but the ocean is always warm enough to swim and snorkel.
