The Yucatan Peninsula is hot year-round.  The two distinguishable seasons are the wet season and the dry season.  The wet season usually starts in June and ends in October, making the dry season generally from November through May. 

The weather here in the dry season is much more desirable and pleasant for most tourists.  The dry season is still hot, but much more tolerable than the wet season.  Although the average temperatures throughout the year don't vary by much . It usually gets about 74°F (23.5°C) in January and  82°F (28°C) in July. The humidity in the summer months makes it feel excruciatingly hot most days, especially to those who aren't used to a humid climate.  In the wet summer, it actually rains most days.   This rain comes in heavy, short spurts usually towards late afternoon.  There is also a strong threat of hurricanes during the wet season (which is why the wet season is often referred to as hurricane season), which have been getting stronger over the past few years.  If the low prices of the summer attract you enough, make sure you completely understand your risks weather-wise before you plan your trip.


With the sun shining on average between 240 and 253 days per year, Cancun is a year-round holiday destination, although certain times of year may be more favorable than others. High season for travel falls between December and April. During these months the weather tends to be sunny, with temperatures hovering around 85ºF (30ºC) during the day and rarely dipping far below 65ºF (18ºC) at night. While this time of year offers the most pleasant weather, it is also most popular with tourists, which drives prices up, especially during the Christmas holiday season between mid-December and the beginning of January. Travelers planning trips near Christmas or Easter and Spring Break should be advised to plan well in advance and book their accommodations early.

Many resorts drop their prices immediately after Easter, so this can be an ideal time to take a more economical vacation while the weather is still bearable. The summer months bring humid, hotter temperatures pushing the 95ºF (35ºC) mark. The hurricane season falls between June and mid-October, so travelers visiting Cancun during these months should pay careful attention to the storm watch. 2005’s Hurricane Wilma caused major havoc and destruction from which Cancun is still recovering. When there is no hurricane, the cooling winds can make the hot summer weather more bearable. The rainy season falls mostly between the end of August and the middle of November, bringing afternoon downpours and occasional floods.

For those that must swim in the "ocean" (Caribbean sea), it is advisable to avoid the 2nd through the 4th week in April (usually the 3rd week).  For about 7 to 10 days, the thimble jelly-fish are mating near the shore.  At best, they are unsightly, at worst, they can cause an allergic reaction if you come in contact with them (which you will if you swim in the sea) and this can result in a fever.  It is best to call ahead to see if the jelly fish season has begun or is over if making last minute plans around this time.
