Weather extremes

How extreme does Puerto Maldonado's weather get?

The hottest, coldest, wettest and snowiest days Puerto Maldonado 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 Padre Aldamiz station 4 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.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Puerto Maldonado has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
102°F Jan 24, 1996

That is about 14°F hotter than a normal January afternoon in Puerto Maldonado (typical high near 88°F).

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.

Puerto Maldonado's record heat sits well above even a hot day for the season — January's 102°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, Puerto Maldonado's warmest days reach the low 90s°F and its coldest nights drop to the mid-60s°F. But across the record it has gone as high as 102°F and as low as 34°F. A single day has delivered over 10 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
