Mexico City's Highest Recorded Temperature

The highest temperature ever officially recorded in Mexico City is 39.5 °C (103.1 °F), measured on May 28, 1995 at the Tacubaya Observatory (Observatorio de Tacubaya), the city's primary historical weather station.

Context

• Elevation: Mexico City sits at ~2,240 m (7,350 ft). High elevation moderates temperatures; extreme heat is rare.
• Typical May Highs: ~26–28 °C (79–82 °F). The 1995 event was a significant anomaly.
• Other Sources: Some records cite 39.6 °C (103.3 °F) on the same date; the difference reflects rounding or station variation (e.g., Aeropuerto Internacional vs. Tacubaya). The Servicio Meteorológico Nacional (SMN) official record is 39.5 °C.
• Climate Change: Heatwaves are increasing in frequency/intensity. 2024 saw multiple days >33 °C, but not surpassing the 1995 record.

Comparison

• National Record (Mexico): 52.0 °C (125.6 °F) — Mexicali, Baja California (July 1995).
• World Record: 56.7 °C (134 °F) — Furnace Creek, Death Valley, USA (1913).
