The latest 7 day Cancun weather forecast, monthly average high and low temperatures, rainfall and ocean temperature plus details on the best weather seasons. Also, see live Cancun weather from one of our live webcams.
Weather can vary greatly from one location to another, separated by only a few miles, especially as you go inland.
! - The Cancun forecast, as in any tropical location, is very
difficult to predict accurately and often times is very pessimistic.
The weather is usually much better than forecasted. Even if it rains, often times the sun returns quickly.
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. Peak vacation season is usually between December and May while off season is between June and November.
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 mid 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. Hurricane season has not started nor is it really a threat in May.

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 during the day and in the 60s at night. 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 only in the 60s and low 70s.
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. February and March are my favorites.
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.
Cancun has some of the best water in the world. Clear and warm with seasonal water temperatures averaging around 80 degrees year round. Even in December, the average temperature is 78 degrees but it is not uncommon for it to be 80 degrees around Christmas. There is no better way to get a break from that winter chill than dipping in the Caribbean.
The Cancun weather forecast for hurricanes is even harder to predict, however due to it's location at the tip of the Yucatan Peninsula, Cancun is right in the middle of the hurricane highway.
About every three years, Cancun is affected by a hurricane with a direct hit occurring every 7 years on average. Wilma was the last major hurricane to hit Cancun directly in late October of 2005 causing an estimated 3 billion dollars in damage and closing down nearly all resorts for an extended period of time.
Other recent hurricanes that impacted the Cancun region were as follows:
The majority of hurricanes hit Cancun in September and October but still can occur anytime between June and the end of November.
