When to Visit Mexico City

Mexico City sits high in a valley, around 2,250 meters above sea level, and that altitude shapes everything about its climate. You get spring-like weather for much of the year, with warm days and cool nights. The city has two main seasons rather than the traditional four. The dry season, running roughly from November through April, brings clear blue skies, plenty of sun, and very little rain. The wet season, from May through October, delivers daily afternoon downpours, higher humidity, and a noticeable drop in ultraviolet intensity as clouds roll in each day. Interestingly, the hottest part of the year often comes right before the rains start in late April and May, while the rainy months themselves are a bit cooler. For a city of its size and latitude, Mexico City's temperatures are remarkably stable. You won't see the extreme heat found in coastal areas. But the sun at this elevation is intense, during the dry months. The shift into the wet season is distinct. Mornings are typically clear and bright. By mid-afternoon, you can almost set your watch to the building clouds and the subsequent heavy, though usually brief, rain shower. The humidity that defines the wetter months tends to linger in the air overnight and into the morning, giving the city a softer feel compared to the crisp, dry air of winter.
