Best time to visit San Miguel de Tucumán

San Miguel de Tucumán is a city of two halves. July scores 98 and December scores 43 — a 55-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. The good window runs May to August — 4 months within ten points of the best.

November is the warmest month at 34 °C and June the coolest at 21.9 °C — a 12.1 °C spread across the year. 163 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season.

There is a real wet season here. January, February, March and December carry the rain — up to 13 wet days in a month — while May to September drop as low as 1. That 12-day gap is the biggest single difference between a good month and a bad one in San Miguel de Tucumán, and it moves further than the temperature does.

Daylight runs from 10.5 hours in winter to 13.8 in summer, enough to notice on a sightseeing itinerary.

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