What Weather to Expect in Mexico City

At a tropical latitude but cool altitude of over 7220ft (2200m), Mexico City’s temperate year-round climate is more separated into rainy and dry seasons than cold and hot, although the temperature does fluctuate somewhat.

October or November through about February see highs in the lower 70°Fs (21°C) with nightly lows of around 43°F (7°C). From March through September or October, enjoy highs of mid to upper 70°Fs (26°C), and lows of around 53°F (12°C), with the warmest months being April and May.

The rain vaguely coincides with the temperatures, but the contrast between rainy and dry seasons is more pronounced, to be sure. Expect afternoon/evening rains, often heavy and not infrequently with hail, from June to September or October. Rains are normally heaviest in July and August. And then you might not see another drop from the end of October through May! (Okay, it does rain from time to time, but very infrequently during that period.)

Built on Lake Texcoco in the Valley of Mexico, Mexico City traps its pollution right in its crater, which also lacks slightly in oxygen because of its altitude too. So air quality isn’t the city’s highlight, although it is improving with government programs to limit driving and other polluting factors. If you suffer from asthma, note that the air quality tends to be better in the summer. It is most common, however, that you won’t notice it much, if at all, while you’re engrossed in your Spanish classes.

So even in the summer, you might well want a jacket or sweater to cover your tee-shirt for the evenings. Definitely bring long sleeves for the winter, as well as a jacket and something even heavier (like a winter coat) for winter nights. Always have raingear and sunscreen too, since even though it’s often not hot nor quite sunny, you’re definitely closer to the sun!
