Weather extremes
How extreme does Palmas's weather get?
The hottest, coldest, wettest and snowiest days Palmas has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
Based on 18 years of daily weather observations (2007–present), from the Tocantins / Brigadeiro Lysias Rodrigues station 14 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.
