Best time to visit Mexico City

December is the best month in Mexico City, scoring 98 out of 100, with September the weakest at 65. The 33-point spread means timing is worth planning around without being decisive. 5 of the twelve months sit within ten points of the best, so there is more than one right answer.

April is the warmest month at 28.4 °C and January the coolest at 21.6 °C — a 6.8 °C spread across the year.

There is a real wet season here. June to September carry the rain — up to 28 wet days in a month — while January, February, March, April, November and December drop as low as 1. That 27-day gap is the biggest single difference between a good month and a bad one in Mexico City, and it moves further than the temperature does.

Daylight runs from 11 hours in winter to 13.3 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are December, January, February. The one to think twice about is September. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
