Weather in Cancun

Cancun is one of the most popular holiday resorts in Mexico, attracting huge numbers of tourists from Europe and the USA each year.

The resort is located on one of the most eastern points of the country, within the Riviera Maya, which runs along the Caribbean Sea.

Cancun is vastly a purpose-built resort, mostly comprised of a thin band of white sandy beach, lined by skyscraper-like hotels and lively bars, with a few ancient Mayan ruins on the outskirts.

Cancun enjoys a tropical savanna climate with a very distinctive wet and dry season. Average temperatures vary very little throughout the year, typically ranging between 23°C (73°F) in the middle of winter and 28°C (82°F) in the middle of summer. They rarely droping below 21°C (70°F) or exceed 34°C (93°F).

Is the water warm in Cancun?
Cancun is blessed with incredibly warm ocean water throughout the year, so you can really enjoy the Caribbean Sea in all its glory. If you're wondering what is the water temperature in Cancun, you won't be disappointed. 

The lowest average Cancun sea temperatures are in February/March, at a still incredibly warm 26°C (79°F).

The highest Cancun water temperatures can be found in July-October, with an average of around 29°C (84°F).

The most popular time to visit Cancun is during the dry season – November to April.  Temperatures are slightly cooler and the relative amount of rainfall is low.

Unfortunately, due to high demand, it's also the most expensive, so expect flight and accommodation prices to be high at this time of year.

The wet season – May to October – is slightly hotter and sees significantly more rainfall. Of the average 1227mm of rainfall that Cancun gets each year, around 984mm falls during these months.

​Due to the more unfavourable weather, Cancun is less popular during this season, so flights and accommodation packages can be snapped up for much lower rates than usual.

Spring Weather in Cancun 

Spring is midway through the dry season in Cancun. Temperatures rise up to average highs of 32°C (90°F) in April, falling to 23°C (73°F) at night.

The difference between daytime and night-time temperatures is fairly significant, and this only increases as the months progress.

Sunshine hours begin to rise in spring, with 10 hours daily in March and April. When precipitation does occur, it's usually a light or moderate rain shower rarely lasting more than a couple of hours.

Whilst thunderstorms are a possibility, they're unlikely during these months. April is the driest month of the season, with just 27mm of rain falling over three days.

The average sea temperature for Cancun stays fairly constant all-year-round, although it's at its coolest during the dry season.

The sea is coolest in February and March when it's just 26°C (79°F), still warm enough to take a dip.

Summer Weather in Cancun 

The wet season in Cancun is much hotter than the dry season, primarily due to the increased humidity caused by intense rainfall.

During this season, Cancun average temperatures range from 27°C (81°F) in May up to 28°C (82°F) in June, July, August and September.

August is the hottest month of the year in Cancun, with average highs of 34°C (93°F) in the middle of the day and average lows of 25°C (77°F) after dark. Thanks to this 9°C (16°F) difference in temperature, after the sun sets, you get respite from the staggeringly high daytime temperatures.


What is the rainy season in Cancun?

A common question when looking at the Cancun weather forecast is: What are the rainiest months in Cancun? Well, the rainy season in Cancun runs from around May to October.  

As you'd expect from the wet season, Cancun experiences a vast amount of rainfall at this time of year.

September is the wettest month in Cancun, with 270mm of rain falling over 10 days, followed by August with 181mm over six days.

However, if you check out our September 2018 records, you can see that the Cancun weather forecast still had plenty of sunny days and warm temperatures. 

When rain falls during the wet season, it's most likely to be bursts of moderate rain and light rain which last for several hours. Thunderstorms are also likely during this season, especially in September.

The summer wet season is the sunniest time of year for Cancun. May, July and August all see 11 hours of daily sunshine each, with June 10 hours and September nine hours. 


June and September are the cloudiest months of the year in Cancun (each has a median cloud coverage of 70%). May, July and August have a relatively low median cloud coverage of 60%-63%.

Combine high temperatures and fairly high cloud coverage with intense humidity and you're almost guaranteed to get a few hot and uncomfortable days if you visit Cancun during the wet season.

At this time of year, relative humidity ranges between highs of 98% (very humid) and lows of 58% (mildly humid).

If the heat gets too much for you, a dip in the sea might help you cool off. Although the average sea temperature for Cancun stays relatively constant throughout the year, it's highest between July and October, at 29°C (84°F).

Autumn Weather in Cancun 

Autumn is a very transitional time in Cancun as the wet season experienced during summer gives way to the dry season for the rest of the year.

Still forming part of the wet season, October sees an average of 177mm of precipitation, over 11 days. This rainfall doesn't immediately stop as the dry season starts, but it does decrease.

November in Cancun sees 104mm of rain over the course of eight wet days, making it easily the wettest month of the dry season.

Strangely enough, during the dry season Cancun sees the fewest sunshine hours of the year. October and November have just eight daily hours, a figure that continues well into December and January.

Sea temperatures begin to drop as the dry season begins, slipping to 28°C (82°F) in November (its warmest month in the dry season). Still warm enough for you to enjoy a swim and, since the temperature is a few degrees cooler than the average high the season, should help you cool off.

Winter Weather in Cancun 

Does Cancun get cold in winter? Well, winter temperatures range from average lows of 21°C (70°F) in December, January and February (the coldest months of the year), up to average highs of 28°C (82°F) for the first two months and 29°C (84°F) in February.

December 2018 in Cancun enjoyed glorious sunshine and an average high temperature of 27°C (81°F), during the first week of the month. 

The pattern continued in January 2019, Although the average temperature dropped a degree or two, Cancun weather saw no rainfall and very little cloud cover.  

The reason Cancun enjoys slightly cooler temperatures during the dry season is due to the north trade winds.

Winds are at their strongest between November and April, when they bring cool breezes to the Mexican coast.

These cooler periods can be a welcome relief from the blistering summer heat of Cancun and the sea is still nicely warm for swimming at 26°C (79°F) - 27°C (81°F).

Cancun Hurricanes and Weather Hazards 

Although the coastal position of Cancun means it gets much more favourable temperatures than those inland, there is one major disadvantage – its vulnerability to hurricanes.

How often does Cancun get hit by Hurricanes?

Cancun hurricane season is officially from June to October, although September and October are the most likely months.

Since 1988, Cancun has been directly affected by three hurricanes.

In 1988, Hurricane Gilbert was declared the second most intense hurricane ever recorded in the Atlantic basin.

It crossed over to Mexico from Cozumel and landed on the Yucatan Peninsula, ravaging the resort with waves of up to 7m (23ft) washing away 60% of the city's beaches.

On October 21 2005, Hurricane Wilma hit Yucatan Peninsula as a Category Four Hurricane, with strong winds of over 240km/h-150mph. The eye first passed over Cozumel, before an official landing just outside Playa del Carmen in Quintana Roo around midnight on October 22.

The eye of the storm was positioned over most of Cozumel for several hours, with blue skies and sunshine visible at times. It drifted northward, passing the centre just to the west of Cancun.

Hurricane Wilma battered Cancun for nearly three days and caused damage estimated to be over $3 billion.

In 2007, Hurricane Dean was declared a Category Five when it landed in Majahual – 310km/190 miles south of Cancun.

Fierce winds at the edge of the impact cone blew sand off 12.1km/7.5 miles of beaches in between Punta Cancun and Punta Nizuc. Tourism operators stopped all holidaymakers from travelling to the resort and instead send empty planes to evacuate tourists already there.

But your chances of being caught in a hurricane are low. On average, Cancun receives a direct hit every 12 years, although it does get brushed by one once every 2.5 years.

There was a near miss in 2007, with Hurricane Dean. Warnings and predictions are accurate and past experience has taught the region how to cope, with the introduction of emergency and evacuation procedures.
