What is the Weather Like in Cancun in January or March or ???

I used data from the Mexican National Weather Service (Servicio Meteorologico Nacional) to compile information that can help answer this question.  For Cancun the records go back about 20 years.

So just how hot is it in Cancun?  The chart below shows the average high and low temperatures and the record high and low temperatures for each month.  As you can see the average high temperature is 90 F or above from April through September.  The hottest month is August with an average high temperature of 95 F. The "coolest" month (January) has an average high temperature of 83 F.  Only the months of December, January, and February have an average low temperature below 70 F.  The record high was 107 F on August 14, 2003 and the record low was 49 F on March 12, 1996.
