The driest month in Mexico is generally February where the most rain will fall in the regions of Quintana Roo, Yucatan, and northern Baja California. June is a rainy month in the southern regions of Mexico such as Chiapas while there may be virtually none in the northern regions of the country. Because of the various different weather patterns throughout the country, there are many different types of vegetation with deserts and temperate regions in the North and tropical and subtropical rainforests in the South.
