How extreme does Palu's weather get?

The hottest, coldest, wettest and snowiest days Palu 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 (1974–present), from the Mutiara 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.

The four kinds of extreme

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

🔥 Hottest day

101°F Mar 3, 1998

That is about 9°F hotter than a normal March afternoon in Palu (typical high near 92°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.

Palu's record heat sits well above even a hot day for the season — March's 101°F is about 9°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, Palu's warmest days reach the low 90s°F and its coldest nights drop to the low 70s°F. But across the record it has gone as high as 101°F and as low as 54°F. A single day has delivered over 12 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.

Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 23 years of daily observations at Mutiara, a weather station, about 5 km from the city centre. The underlying daily records come from NOAA's global station network.
