Weather extremes

How extreme does Fray Bentos's weather get?

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

Based on 50+ years of daily weather observations (1971–present), from the Mercedes station 27 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.

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Fray Bentos's record heat sits well above even a hot day for the season — January's 109°F is about 19°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, Fray Bentos's warmest days reach the low 90s°F and its coldest nights drop to the low 40s°F. But across the record it has gone as high as 109°F and as low as 17°F. A single day has delivered over 7 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
