Best time to visit San Luis Potosí

December is the best month in San Luis Potosí, scoring 98 out of 100, with June the weakest at 66. The 32-point spread means timing is worth planning around without being decisive. 6 of the twelve months sit within ten points of the best, so there is more than one right answer.

May is the warmest month at 30.6 °C and January the coolest at 21.3 °C — a 9.3 °C spread across the year. Around 53 days a year top 30 °C, concentrated in May and the months either side.

There is a real wet season here. June to September carry the rain — up to 17 wet days in a month — while January, February, March, April, November and December drop as low as 1. That 16-day gap is the biggest single difference between a good month and a bad one in San Luis Potosí, and it moves further than the temperature does.

Daylight runs from 10.8 hours in winter to 13.5 in summer, enough to notice on a sightseeing itinerary.

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