Although the southern part of mexicos central plateau lies in the tropics, the region

has a temperate climate

Explanation:

The central plateau of Mexico extends from the border with the United States to the central-southern part of the country. Before the plateau meets the transversal mountain range in the south, it crosses the Tropic of Capricorn and officially enters the tropical latitudes.

Because of its elevation, however, the climate in the southern part of the central plateau is cool and rainy in the summer and cool and dry in the winter. The warm season can hardly be described as hot and lasts only about two months.
