Whatever you do, do not look at the weather reports for the Yucatan before you go!
The weather is so changeable, that to try to predict the weather is a fool’s errand.
You can be sure it will be sunny and warm for the majority of your trip no matter
what time of year you go. The warm trade winds buffet the coast all year long, so
even the summer is nice. Here are the seasons:
Winter: Sunny and warm, with less humidity, the occasional cool evening. Water temps in the 70’s, daytime highs in the 80’s. Great season for inland exploring ruins or colonial cities like Merida.
Spring: Sunny and warm, days are lengthening, so lots of time for the beach and excursions. Breezy with daytime highs in the high 80’s.
Summer: Sunny and warm, with an occasional passing thunderstorm, daytime high’s in the 90 degree range. This is a great time to be in Mexico, it stays light longer and you can
linger on the beach til late. Water temps fabulous, in the 80’s, you will never want to get
out of the sea! Hot inland at ruins or jungle settings.
Fall: Sunny and warm, cooler nights begin to creep in. Quiet beaches in the low season
and the water stays nice and warm.
As you can see, you can expect sunny, warm days whenever you visit the Yucatan.
Try every season, you will find something to like about each one!
