If you are looking for a warm year-round climate similar to south Florida, Cancún may be the place for you.
Throughout the year, average high temperatures range from the low 80s to the mid-90s, while the lows seldom dip below the high 60s. Cancún has a tropical climate, specifically a tropical wet and dry climate. There are few major temperature differences throughout the seasons, but the summer/fall rainy season brings a big change to the region, dropping about two-thirds of Cancún’s annual rainfall of over 51 inches in the June through November period.
You will find Cancún’s best weather November through February when average highs range from the low 80s to the mid-80s and nighttime temperatures hover around 70 F. During these months refreshing breezes blow from the north. March and April is when the weather becomes drier and hotter. The hottest months are May through September.
A Caribbean coastal city, Cancún’s humidity is above 70 percent all year, especially during hurricane season when humidity can reach 75 percent. Combined with high temperatures over half of the year, it can get a bit uncomfortable.
If you are a water sports enthusiast or just want a dip from time to time, you will be happy to know that the Caribbean is always warm, ranging from 78 F to 80 F in winter and 82 F to 84 F during the summer. Underwater visibility in Cancún is usually around 50 to100 feet. In nearby Cozumel, the underwater visibility can reach up to 200 feet.
Because it is located on the Caribbean Sea with a tropical climate, Cancún lies within a very active hurricane belt. About every 12 years a hurricane directly strikes Cancún, and about every two and a half years the city is brushed by a hurricane. Hurricane Wilma – a Category 4 storm in 2005 – was the last major hurricane to directly strike Cancún. Hurricane season is July through November. The most likely months for a hurricane to occur are September and October.
And like most of Mexico, the region can experience earthquakes from time to time.
