Understanding Mexico City temperature by month is essential for anyone planning to visit or move to this high-altitude metropolis. Located in a valley at approximately 2,240 meters (7,350 feet), the capital enjoys a mild climate year-round, defying the expectations many have for a city so close to the tropics. Unlike coastal regions, the temperature here is less about sweltering heat and more about comfortable days and cool evenings, with distinct patterns shaped by altitude and the rainy season.
Seasonal Overview: The Two Main Periods
The city’s climate is primarily divided into two major seasons, which dictate the Mexico City temperature by month in a predictable way. The majority of the year is spent in a warm, dry period that runs from November to April. During this time, the mercury typically stays pleasant, making it the most popular time for tourism. The alternative is the wet season, spanning from May to October, which brings higher humidity, frequent afternoon showers, and a slight but noticeable shift in daily temperature ranges.
The Dry Season: November to April
November to February: Peak Comfort
During the core of the dry season, the Mexico City temperature by month reflects near-perfect conditions. Daytime highs usually hover between 21°C and 23°C (70°F to 73°F), providing ample sunshine for exploring the Zócalo or Chapultepec Park. Nights, however, tell a different story, often dropping to 6°C to 9°C (43°F to 48°F). This significant dip means that locals and visitors alike rely on light jackets or sweaters after sunset, a phenomenon that defines the city’s evening ambiance.
March to April: Warming Up
As the dry season wanes, the Mexico City temperature by month begins a gradual ascent. March and April are transitional months where the sun feels warmer on the skin, and the likelihood of a cool breeze decreases. Daytime averages climb to a range of 23°C to 25°C (73°F to 77°F), signaling the approach of summer. Evenings remain cool but become more comfortable, rarely requiring heavy layers, making these months ideal for outdoor dining and evening strolls.
The Wet Season: May to October
May: The Threshold of Rain
May serves as the gateway to the wet season, and the Mexico City temperature by month shows a steady climb toward summer peaks. Temperatures rise to an average high of 25°C to 26°C (77°F to 79°F), accompanied by increasing humidity. While the rain is not yet constant, the air feels heavier, and the city prepares for the dramatic afternoon thunderstorms that will soon become the norm.
June to August: Rain and Relief
During the heart of the wet season, the Mexico City temperature by month reveals a pattern of consistency. Daily highs generally remain stuck around 24°C to 25°C (75°F to 77°F), while lows hold steady at 9°C to 11°C (48°F to 52°F). The defining feature of these months is the afternoon deluge. The rain arrives suddenly, often cooling the air temporarily before clearing to reveal crisp, clear evenings. The advantage for visitors is thinner crowds and lush, green scenery throughout the historic center.
