Water temperature of the Caribbean is influenced mainly by two things.
• The sun's angle
This is a seasonal influence,
heating the water more
during summer months than in winter when the sun is over the southern hemispere.
see more on sun angle here.
• Ocean current
The prevailing ocean current (called he Yucatan current) pulls water from the equator
and moves it north to the gulf
of Mexico, passing along the
coast of Cancun on it's way.
This is the reason Cancun's
water stay warm during the winter months.

During summer months, the sun is at its
most powerful for the northern hemispher and the Caribbean absorbs much of the sun's power. Temperatures rise to an average
of 84°f (29°c), but can reach
86°f (30°c) in areas. This heat
has the potential to feed tropical storms and hurricanes.
In Winter the sun is now most powerful over the southern hemisphere. Cancun's waters can finally cool, but warm currents moderate the temperature.
