Best time to visit Mexico City: month-by-month weather (2026)

The best months to visit, based on visit scores, are January, February, March, and April. During this stretch, daytime highs run from about 23 degrees Celsius in January up to roughly 28 degrees in April, overnight lows stay mild between about 8 and 13 degrees, rainfall stays low at 4 to 11 millimeters a month, and sunshine climbs from about 10 hours a day toward more than 12 hours a day by April.

This window overlaps with part of the wider peak season, which also includes July and August, so travelers chasing the top-rated months should expect more visitors and higher demand than in the quieter middle of the year. The trade-off for skipping January through April is heavier rain: July receives about 262 millimeters and August about 249 millimeters, well above the 4 to 11 millimeters typical of the best months, while May and June also see rain climb quickly to 83 and 184 millimeters respectively as the wet season builds.
