Map of the distribution of tropical dry forest in Mexico

Tropical dry forests can be found in eastern Mexico, but the largest portions are located in western Mexico. Large portions of tropical dry forests span across "southern Sonora to northern and central Chiapas" (Ceballos and Garcia 1349).

As you can see by the green coloring, tropical dry forests occur in Baja California, Sonora, Sinaloa, Tamaulipas, all the way down to Chiapas. There is also a pretty large patch in Yucatan.
