Ciudad de México activates multiple cold alerts amid ongoing low-temperature spell

The Mexico City government has issued multiple cold alerts over several days from March 19 to March 26, 2026, as temperatures dropped as low as 1°C in several boroughs, according to Lopez Doriga Digital and El Financiero. The cold spell prompted the activation of both orange and yellow alerts, with Tlalpan consistently under orange alert and boroughs such as Álvaro Obregón, Cuajimalpa, Milpa Alta, Magdalena Contreras, and Xochimilco under yellow alert.

Temperature forecasts during this period generally ranged from 1 to 6 degrees Celsius, with the coldest conditions expected in Tlalpan where nighttime lows were predicted between 1°C and 3°C. Other areas such as Álvaro Obregón and Xochimilpa were anticipated to experience minimums closer to 4°C to 6°C, accompanied by morning frost and clear skies followed by warm afternoons and occasional isolated showers, as reported by El Financiero.

Authorities have emphasized precautionary measures including wearing layered clothing, maintaining hydration, protecting vulnerable populations and animals, and ensuring proper ventilation when using heating devices to avoid indoor hazards, according to multiple updates from Lopez Doriga Digital. The government has advised residents to monitor weather updates and to contact emergency services if necessary during these cold periods.

Compounding the weather-related challenges, the government also issued a yellow alert for heavy rains affecting 10 boroughs on March 24, highlighting the variable and shifting weather conditions entering the spring equinox, as noted by El Financiero. Strong winds during this time have led to fallen trees and other related risks in parts of the city.

Looking ahead, Mexico City officials are expected to continue monitoring temperature fluctuations closely as the transition into spring progresses. The persistence of low temperatures despite the season change underscores the need for ongoing vigilance and preparedness for possible frost and cold-related impacts on residents and infrastructure in affected boroughs.
