This guide breaks down what each month typically feels like on the Akumal coast of the Riviera Maya, including average temperatures in °F, humidity, rain chances, and what that means for beach and pool days, snorkeling, cenote and Tulum day trips, and time at this all-ages, all-inclusive resort, where meals and drinks are part of your stay.

The most consistently comfortable stretch is usually December–April (often around 78–85°F highs with lower humidity), while June–September tends to feel hotter and more humid (often around 87–90°F) with higher rain risk.
