MapChick's famous maps & travel guides

Cancun and the Riviera Maya are located along a stretch of current that pulls warm water from the equator, up the coastline, then into the Gulf of Mexico. These waters cool along the way, but the water temperatures never drop below 78° farenheit (26° celsius) druing winter months. During summer months, when the sun is more directly over Cancun, the water temperature rises to 84°—we love to visit during this time, the ocean feels like bathwater.

These warm water temperatures are also what fuels hurricanes. In fact, hurricanes play an important role in nature. They draw heat from the ocean and spin it off into the atmosphere, helping to regulate water temperatures and protect marine life cannot thrive in hotter temperatures.
