The climate of Mexico City (Mexico)
Mexico City is the capital of Mexico and one of the largest cities in the world with a population of more than 20 million. The city is situated at an altitude of more than 2,000 meters in the Valley of Mexico and is surrounded by volcanoes and mountains. Because of its situation warm air remains stationary. This causes high temperatures; especially during the winter it is much warmer in the city than in its direct surroundings. Another serious problem is air pollution which causes a serious smog problem. Because of the air pollution and the altitude at which the city is situated people who aren’t used to these conditions may experience respiratory problems. People who already have a lung condition should bear this in mind when travelling to Mexico City

Two seasons
According to the Köppen climate classification Mexico City has a moderate savannah climate (type Cwb) with two distinct seasons. A dry season from the second part of October till the second part of May and a wet period from the second part of May or the beginning of June till the second part of October. Large amounts of rain are not uncommon during this period. However, these showers clear the skies. Because of this it may feel muggy caused by high humidity figures instead of the polluted air. Because of its geographical situation the southern part of the city is wetter than the northern part.

There are only few differences in temperature between summer and winter. Maximum temperatures are 20-30 degrees Celsius all year round. During the night temperatures drop to 4-14 degrees Celsius. The highest temperatures can be recorded during spring. When the rainy season begins temperatures are tempered during the day and temperatures of 23-25 degrees Celsius can be recorded. Within 24 hours the difference between maximum and minimum temperatures is quite large. The difference between daytime and night time temperatures is 12-20 degrees Celsius on average. During the winter subzero temperatures may occur during the night because of a cold current coming from the north. Snowfall may occur on the Mexican high plains. However, snowfall hardly ever occurs in Mexico City.

During the hurricane season from June till November there is a small risk of a hurricane reaching Mexico City. Most hurricanes that make landfall in Mexico weaken as soon as they reach the mainland; when they have reached Central Mexico they will often have weakened to a tropical depression causing high precipitation figures. Apart from flooded sewer systems and failed crops because of floods damage because of fierce winds is uncommon.

More climate information
Climate figures are very useful but don’t present a general impression of the climate and the eventual weather circumstances within a certain period. The figures don’t always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we offer useful extra climate information for each month of the year:
