What the weather will be like for your vacation in Cancun Mexico

Cancun weather

Cancun weather is what everyone is concerned about when coming on vacation. We thought we would put together this guide for you so you can know what to expect for weather.

Cancun Weather

You will be pleased to know that the average daily temperature is 27 degrees Celsius or 80 degrees Fahrenheit. This allows you to lay on the beach any day of the year and the ocean is warm enough to swim in year round as well, although locals tend not to swim from December until March. It also seems like we have sunny days with blue sky all the time here except when we get a rain storm. In fact we have 340 days of sunny weather here!

Average Temperatures for Cancun

Cancun weather


May often feels the hottest month on average in Cancun but in fact is July and August. It is 29.5 degrees Celsius or 85 degrees Fahrenheit. That might not sound too bad to you but remember that the temperatures at night do not go down very much. Buildings absorb the heat in the day and radiate the heat back at night, so if you don’t have air conditioning it can be hot for you.

Tip: The old saying “it is not so much the heat it is the humidity” comes into play here. We are in the tropics and the humidity levels are often very high. This can make it feel even hotter. This is not a problem if you are by the pool all day or swimming in the ocean but remember outside of these two places it can feel very warm. Drink lots of liquids, wear light clothes and plan your day around the hottest times.

The coldest time of the year is January which has an average temperature of 23 degrees Celsius or 74 degrees Fahrenheit. That might sound a little cool but the days are beautiful with the night temperatures drop some to give you good sleeping weather. Of course if you are living up north these January temperatures are going to seem heavenly! You will see people using a light jacket at night sometimes in the winter.

Daylight Hours in Cancun

We have on average 9.25 hours of daylight a day here. From October until January there are 8 hours of daylight a day and these are the shortest days. May has the longest days with 11 hours of light.

Average Rainfall in Cancun

If you are planning your days on vacation basking in the sun, then this might be important for you to know!

The most rain occurs from June until October. The good news is that it often only rains for 1-3 days and then it is over or there is a shower and then it goes away. The month with the least rain is February or MarchOctober has the most rainfall. This often depends on which months hurricanes or tropical storms pass through.

When is the dry and wet season in Cancun?

Most people want to be here in the sunny season and not be sitting inside during the rain. The woods or “jungle”  is actually semi tropical rainforest. In the dry season they can look very dry and almost dead looking. The contrast between the “wet” or “green” season to the dry season is very noticeable. Of course with the wet season comes more mosquitos in rural areas outside of the city.

What is the water temperature in Cancun?

Going swimming all year round is very comfortable to do. The sea temperature changes only a few degrees up and down. The average temperature is 81.5 degrees Fahrenheit or 27.5 Celsius.  August is the warmest water month.

When is the best weather in Cancun?

Well most people would say:

1. March-because it s not too hot and we don’t have too much rain

2. November– because it is cooling down and there is not too much rain. Things are left very green after the summer rains as well, so things look nice.

But really all year is a great time to come to Cancun and these are just opinions of people. It is just bad when we experience an occasional full week of rain and it just happens to be on the week you come.

What about hurricanes?

Yes we live in the tropics and there are hurricanes. We don’t get as many as you might expect and the nice thing about those storms is the amount of time you have for a warning. We on average have a bad hurricane every 10 years and often we often don’t have any hurricanes for several years in a row. If you are here on vacation and one approaches, all of the hotels are very prepared to help guest fly home or take cover. Hurricane season in the Atlantic is June through November.

Natural Cycles of weather in Cancun and the Riviera Maya

Starting in March the temperature starts to get warmer and after months of dryer weather the summer rains approach. The heat of summer makes clouds form and they break into rain showers and cool things down a bit until things heat up again.  Having a regular cycle of this will take energy out of the atmosphere and we have a less risk of hurricanes. In summer expect to change clothes frequently because of the heat. Locals often change three times a day. Be sure you shower often to clean sweat off your skin. After the summer things are very green and things cool off a bit. In the “winter” months it can get cooler in the evenings and a light jacket might be nice. But we never get to freezing.  Christmas and New years are often nice weather and people are on the beach in swimsuits for the holiday.

What is the weather in Cancun today?

For all the latest weather in Cancun, you can check wind guru website. Once you are on the page, just enter “Cancun” in the box where is says “type spot name”. It is a technical site but often has very good predictions as to what the weather will bring.  This can give you a somewhat good idea of what the weather is for the week. Many boat people will use this site for Cancun weather predictions.

It is however harder to predict the tropical weather here and sometimes just good to look outside in the moment to see what it is like out.

    Don’t know what to expect for Christmas time weather there. Is it warm enough to swim?

    • Hello Victoria

      The weather in Cancun is very nice in December. In fact it is a very popular time for tourist to come. You will be able to spend the days on the beach and swimming as well.

  2. What’s the weather like now that the storms have been passing through?

    • Hello

      We had Harvey pass over us and it was more just a small rain event. It was nothing really. We were fortunate compared to what happened in Texas. The weather has been calm recently.

  3. With all the hurricanes in the Caribbean how is the weather been in Cancun lately? We arrive on October 14th.

    • Hello Fennel

      The hurricanes have gone around us and we have had a calm late summer. We are experiencing the random daily shower which is typical for this time of year. Other then that, you can get some good beach time in.
