June rainfall shatters records in Mexico City, exceeding historical averages

Mexico City experienced a record-breaking June in 2026, with accumulated rainfall reaching 241 millimeters. This figure significantly exceeded the historical monthly average of 126 millimeters and surpassed the 232 millimeters recorded in June 2025, which was itself one of the most intense rainy seasons in the capital's history.

According to José Mario Esparza Hernández, secretary of Integral Water Management, this trend of increased rainfall has been consistent since March. Each subsequent month has seen higher accumulated rainfall compared to the previous year. "Last year, it was the most intense rainy season in the records; last year in June there were 232 millimeters. And yesterday, with yesterday's rain, we closed the month of June with 241 millimeters," Esparza Hernández stated.

The secretary further detailed that on June 30 alone, over 15 million cubic meters of rain fell across the city. The precipitation was widespread, with particularly heavy rainfall concentrated in the Gustavo A. Madero, Venustiano Carranza, Iztacalco, and Iztapalapa boroughs.

Looking at the year-to-date figures, the total accumulated rainfall from January 1 to June 30, 2026, also surpassed previous records. The historical average for this period is 224 millimeters, while June 2025 saw 355 millimeters. In 2026, the total reached 453 millimeters by the end of June, exceeding both benchmarks.

This sustained period of heavy rainfall follows a pattern observed since March, indicating a significant shift in precipitation levels for Mexico City. The data suggests a continuation of intense weather patterns, with implications for water management and infrastructure.
