Weather extremes

How extreme does Salto del Guairá's weather get?

The hottest, coldest, wettest and snowiest days Salto del Guairá 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 Saltos Del Guaira station 5 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.

Salto del Guairá's record heat sits well above even a hot day for the season — September's 105°F is about 20°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, Salto del Guairá's warmest days reach the low 90s°F and its coldest nights drop to the low 50s°F. But across the record it has gone as high as 105°F and as low as 27°F. A single day has delivered over 8 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
