Cancun Weather, Time Zone & Travel Guide
Cancun sits at 21.2°N on Mexico's Caribbean coast in the Yucatán Peninsula, giving it a tropical wet-dry climate with warm turquoise waters, white sand beaches and some of the most intense UV indexes in the world. The city is famous for its Hotel Zone (Zona Hotelera), but knowing the live weather — especially UV index and hurricane risk — is essential for planning safe, enjoyable days in this sun-soaked destination.
Cancun Climate by Season
Dry Season (December–April): The prime tourist window. Temperatures range from 75–85°F (24–29°C) with low humidity, clear skies and calm seas. UV index still hits 9–11 even in "winter" — sun protection is year-round necessity in Cancun.
Shoulder Season (May–June): Getting hotter (85–90°F / 29–32°C) with rising humidity. Occasional afternoon storms begin. UV index peaks at 12–14 (Extreme). Fewer crowds and lower prices than high season.
Hurricane Season (July–November): Hot, humid and subject to tropical storms and hurricanes. July–August see daily afternoon downpours. September–October is peak hurricane risk for the Yucatán — monitor NOAA advisories closely. Despite the risk, many travelers visit with good results in July–August when storms are less organized.
Cancun Time Zone
Cancun uses Eastern Standard Time (EST, UTC-6) year-round — uniquely, Cancun opted out of Daylight Saving Time in 2015, aligning permanently with US Central Standard Time in winter and Eastern Daylight Time in summer. This makes it one of the more confusing time zones for US visitors: check the live clock above for the exact current time.

What to Pack for Cancun
Cancun's UV index regularly hits Extreme (11–14) year-round — reef-safe SPF 50+ is essential (Cancun's reefs are protected, so chemical sunscreens are banned in many beach areas — bring mineral-based SPF). UV400 polarized sunglasses, a wide-brim hat and a large insulated water bottle keep you protected and hydrated. A compact umbrella handles the afternoon tropical downpours. A travel eSIM with Mexican data coverage ensures connectivity from the airport through the hotel zone. Waterproof sandals and a dry bag protect against the inevitable beach splashing.
