Visitors who are accustomed to the heat of Mexico’s beaches may be surprised by the temperate climate of Mexico City. At this altitude it rarely gets too hot, and even in the summer months you may need a sweater. The warmest months are April and May, before the rains start. From late May or early June through September warm, sunny days often change rapidly to cool, wet evenings. The chilliest time is between November and February, when thermal inversion is also likely to occur. This is also when air pollution tends to be at its worst.
