Weather extremes

How extreme does Potsdam's weather get?

The hottest, coldest, wettest and snowiest days Potsdam 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 (1971–present), from the Potsdam station 2 km away. Updated through February 2026 — 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 Potsdam has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
102°F Jul 20, 2022

That is about 25°F hotter than a normal July afternoon in Potsdam (typical high near 77°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.

Potsdam's record heat sits well above even a hot day for the season — July's 102°F is about 25°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, Potsdam's warmest days reach the high 70s°F and its coldest nights drop to the high 20s°F. But across the record it has gone as high as 102°F and as low as −5°F. A single day has delivered over 4 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 30 years of daily observations at Potsdam, a weather station, about 2 km from the city centre. The underlying daily records come from NOAA's global station network.
