Weather extremes

How extreme does San Miguel de Tucumán's weather get?

The hottest, coldest, wettest and snowiest days San Miguel de Tucumán has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 34 years of daily weather observations (1991–present), from the Teniente Benjamin Matienzo station 11 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

San Miguel de Tucumán's record heat sits well above even a hot day for the season — November's 113°F is about 24°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, San Miguel de Tucumán's warmest days reach the low 90s°F and its coldest nights drop to the mid-40s°F. But across the record it has gone as high as 113°F and as low as 21°F. A single day has delivered over 19 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
