Understanding Mexico City temperature by month is essential for planning any visit to this high-altitude metropolis. Situated in a valley at approximately 2,240 meters (7,350 feet), the capital experiences a unique climate that differs significantly from other tropical cities at similar latitudes. The city enjoys a subtropical highland climate, characterized by mild temperatures year-round, distinct wet and dry seasons, and minimal temperature variation between the hottest and coldest months.
Annual Climate Overview
The defining feature of Mexico City temperature by month is its remarkable consistency. Unlike coastal cities or those at sea level, the temperature range here is narrow, typically oscillating between 12°C (54°F) and 26°C (79°F) annually. This stability is due to its elevation, which acts as a natural thermostat, preventing the extreme heat found in lower-lying areas and the intense cold common at higher altitudes. The year is divided into a long dry season, running from November to April, and a wet season spanning May to October, with temperature patterns aligning closely with these precipitation cycles.
Temperature Patterns in the Dry Season
November to April
During the dry season, Mexico City temperature by month settles into a comfortable and predictable rhythm. This period represents the peak tourist season, thanks to the low humidity and minimal rainfall. Daytime temperatures usually hover between 22°C and 26°C (72°F to 79°F), providing ideal conditions for exploring the Zócalo, Chapultepec Park, and the city's colonial center. Evenings, however, can be quite cool, with temperatures often dropping to 6°C to 10°C (43°F to 50°F), necessitating a light jacket or sweater. The crisp, clear air results in significant diurnal variation, where the difference between the warm afternoon and the cool night is pronounced.
The Arrival of the Wet Season
May to October
As the wet season begins, Mexico City temperature by month shows only a slight upward shift, maintaining its characteristic mildness. May and June are the hottest months, with average highs reaching their peak of around 26°C to 27°C (79°F to 81°F). The defining feature of these months is not the heat but the humidity and the daily afternoon thunderstorms. These deluges, while intense, are usually short-lived, clearing the air and often leaving the city cooler and fresher. The thermal sensation during this period can feel warmer due to the high moisture levels, even though the actual thermometer reading remains moderate.
