When Will Rains End in Mexico City? Civil Protection Issues Special Advisory

Mexico City is currently enduring a period of heavy rainfall, prompting questions from residents about when the wet weather will subside. According to the National Meteorological Service (SMN) of Mexico's National Water Commission (Conagua), the country's rainy season is closely tied to the tropical cyclone cycle, which officially commenced in May and generally extends through late autumn.

An special advisory from the Secretariat of Integral Risk Management and Civil Protection (SGIRPC) indicates that the interaction of low-pressure systems with moisture from both the Pacific Ocean and the Gulf of Mexico consistently fuels storm clouds over the Valley of Mexico. Historical data and projections suggest that the rainy season in the central region typically concludes around late October or early November, coinciding with the withdrawal of tropical systems and the arrival of cooler air masses.

While brief periods of clear skies may occur, the flow of moisture remains active. The SGIRPC emphasizes that precipitation is expected to continue with varying intensity throughout the summer and into the fall, with July and August historically seeing the highest rainfall accumulation. Authorities are also monitoring a low-pressure zone that is expected to evolve into a tropical cyclone between June 27 and 29.

Civil Protection warns that areas in the city's hilly regions, such as Álvaro Obregón, Cuajimalpa, Magdalena Contreras, and Tlalpan, face a higher risk of water accumulation and landslides due to soil saturation. To mitigate these risks, the government advises citizens to maintain drainage infrastructure by not discarding trash in public areas, check for roof leaks, and ensure downspouts are clear. Drivers are also urged to reduce speed and use headlights during rainfall.
