Temperature in Cancun During December
Despite it being one of the ‘colder’ months of the year (only January has a cooler average high temperature) you can still expect about 26 of the 31 days of December to reach over 80F during the day, with about 4 over 90F.
Typical daily average low temperatures are high 60’s which you’ll encounter, more often than not, very early in the morning. Occasionally, what locals call ‘north fronts’ will move down from central USA and bring cooler weather at this time of year.
Cold fronts can occasionally push overnight temperatures into the 50s.
Rain and Humidity in Cancun During December
December is outside the official Atlantic hurricane season and hurricanes affecting Cancun at this time of year are uncommon.
Looking at rain in Cancun during December you should expect about 12 rainy days throughout the whole month. As usual this does not mean that it will rain all day for 12 days, just that on about 12 days rain will fall somewhere in the Cancun area for an unspecified duration and it could be heavy or it could be so light it’s barely noticeable.
December is the 7th wettest month of the year so it’s fair to say it’s neither a dry month nor a wet month when looking at the year as a whole.
Average relative humidity is about 78%, and average wind speed throughout the month is a gentle 7.6mph.
December in Cancun
Early December follows the continuing pattern from November and is fairly quiet. However, as Christmas approaches occupancy levels soar and from Christmas through New Year Cancun hotel prices are at their highest price of the year. See our Christmas in Cancun guide for festive meals, Christmas Eve and Christmas Day plans, and booking advice.
Christmas marks the start of high season in Cancun and occupancy levels remain high from now until the end of May as snowbirds tire of the cold weather in the North and seek their way south. This is particularly true for Canadians and it is they who will form the majority of tourists in Cancun from Christmas through the first few months of the year.
December is a great time of year to get out and about and experience what the Yucatan Peninsula has to entertain you. While you may find on occasion that some water based tours are cancelled due to high seas all land based tours will be in operation 7 days a week and due to the lower temperatures and occupancy it is the perfect time to enjoy them.
