The Mexican monsoon began on Monday, July 13, and will end in September, the National Water Commission reported.
The phenomenon mainly affects the states of Sinaloa, Sonora, Chihuahua and Durango. It causes short but torrential rains that help combat drought in the northwest of the country.
Conagua explained that the monsoon forms from the convergence of winds from the Atlantic, the Gulf of Mexico, the Pacific and the Gulf of California. Rainfall is usually intense but brief.
The agency also forecasts between 29 and 36 tropical cyclones for 2026 in the Pacific and Atlantic combined. Between 18 and 21 systems are expected in the Pacific.
