Mexico City Experiences Record-Breaking Rainfall on June 28
Mexico City, July 1 – On Sunday, June 28, Mexico City experienced an unprecedented volume of rainfall, with official records indicating 42 million cubic meters of water. This event marks the highest precipitation recorded since the beginning of the current administration, led by Clara Brugada, as confirmed by Mario Esparza Hernández, Secretary of Comprehensive Water Management (Segiagua).
Esparza Hernández stated that the city registered 28 millimeters of rain, equivalent to nearly 29 liters per square meter. When combined with the metropolitan area of the State of Mexico, the total volume of rainfall exceeded 73 million cubic meters. This recent downpour surpasses the intensity of any previous single day, including the most intense rainy day of 2025.
Comparison with Previous Years
The Secretary of Segiagua highlighted that the rainfall on June 28, 2026, was 8.3% greater than the previous record set on June 29, 2025. In 2025, authorities recorded 26 millimeters of rain, a figure now surpassed by the recent event. This indicates a continuing trend of increasingly intense rainy seasons, with 2025 having been the most intense on record, and 2026 already showing signs of exceeding it.
Clara Brugada, the head of government for the capital, acknowledged that the precipitation was particularly severe in the vicinity of the Mexico City Stadium. In response to this, the local secretary confirmed that special operations for flood prevention would be implemented around the stadium and Paseo de la Reforma, especially for today, July 1, when the National team is scheduled to play.
Historical Context of Rainfall and Drought
According to the National Meteorological System, as of June 29, 15 functional rain monitoring stations were active across at least nine mayoralties. An historical analysis of data from these stations reveals that the recent record on June 28 is not an isolated incident but rather the culmination of a period of extreme climatic volatility.
After several years of inconsistent records, 2025 emerged as the year with the highest documented rainfall in the last decade for most areas, starkly contrasting with previous periods of drought. Stations that have recorded historical peaks in high rainfall include:
- Colonia Santa Ursula Coapa (Coyoacán): Led historical records with 196.1 mm in 2025.
- El Guarda (Tlalpan): Reached a volume of 187.4 mm in 2025.
- Tlalpan (same demarcation): Recorded 154.5 mm in 2016.
Conversely, the capital has also faced years of drought and months with critically low humidity levels. Stations that have registered the lowest data include:
- Playa Caleta 454 (Iztacalco): Recorded an absolute minimum of 0.1 mm in 2019.
- Desviación Alta Al Pedregal: Registered merely 5.7 mm in 2019.
- El Calvario 61 (Tlalpan): Presented a critical level of 29.9 mm in 2023.
These alternating patterns of acute droughts and record-breaking rains underscore the significant climate challenges facing Mexico City, necessitating robust infrastructure and proactive management strategies to mitigate their impact on the urban environment and its inhabitants.
