The data journalism outlet Serendipia has created a heatmap tracking the progression of drought across Mexican states from 2003 to 2025. Using government data from the Mexico Drought Monitor, the visualization shows month-by-month drought intensity for each state. It uses a six color scale: blank squares indicate no drought, while shades from light yellow to dark red represent increasing severity of drought. The map reveals that drought has become more frequent, intense, and persistent in northern states like Sonora, Chihuahua, and Durango, especially in the last five years. More generally, the chart highlights how drought in Mexico, once cyclical, is now becoming a persistent feature across much of the country.
