The latest Cancun weather forecast, seasonal temperature and rainfall averages plus details on the best weather seasons.
The weather in Cancun is generally warm all year, however, it can occasionally be cool and there are definitely better times of the year than others to plan your vacation. "On" season is usually between December and May while "off" season is between June and November.
Weather can vary greatly from one location to another, separated by only a few miles. Hint ! - Weather in Cancun, and in any tropical location, is very difficult to forecast accurately and often times are very pessimistic. The weather is usually much better than predicted. In addition, even if it rains, often times the sun returns quickly.
Hurricane season starts in June and lasts until November with an occasional threat in December. This time of year often has higher temperatures, more rain and higher humidity.
I have been there several times in early December. Most of the time the Cancun weather has been in the high 70s to low 80s for highs and in the 60s for low. However, I was also there during the last International Global Warming Conference and it was the coldest week in the last 100 years with lows in the 50s and highs in the 60s and low 70s.
My favorite time, and I think the month that has the best Cancun weather, is May. Spring break is over, daytime highs are in the 80s and nights in the mid 70s. The humidity level is not too bad, winds are generally light and the ocean water is in the 80s. This is the best time to experience all the great Cancun activities. In addition, hurricane season has not started nor is it really a threat in May.

The rainy season coincides with hurricane season. The summer months are very humid with much more rain than in the winter months. However, there are many summer days that have great weather. Hint! - If you don't like really hot and humid, go to Cancun in the spring.
The coastal weather is also tempered by the Caribbean and you must also consider whether you will be traveling inland to explore the Mayan Ruins such as Chichen Itza. Hint! - unless you enjoy highs near 100 F and humidity at 90% or above, avoid the inland locations beginning in early June through November. All of the Mayan ruins require lots of walking and climbing. The wintertime temperatures will make the trip much more enjoyable.
