When to go Yucatán Peninsula ?
Everything will depend on your desires on the spot! You can travel all year round in the peninsula, each season has its advantages: climate, affluence and prices, carnival and other cultural events, specific activities (kitesurfing, swimming with whale sharks, birdwatching...). The dry season, from November to April, is the most pleasant to visit the Mayan sites; March is the most festive month in Cancún; from April to July, a perfect time for swimming and lazing around..
Mexico, including the Yucatan, has a hot and humid climate. From May to September, it is particularly hot and humid, and in general, the weather is better in the interior of the country where the climate is more temperate. The high tourist season in Mexico, and in Yucatan, is concentrated in the months of July/August and December/January.
