How extreme does Belford Roxo's weather get?

The hottest, coldest, wettest and snowiest days Belford Roxo 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 Campo Delio Jardim De Mattos station 12 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.

Belford Roxo's record heat sits well above even a hot day for the season — February's 108°F is about 14°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, Belford Roxo's warmest days reach the low 90s°F and its coldest nights drop to the low 60s°F. But across the record it has gone as high as 108°F and as low as 41°F. A single day has delivered over 20 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
