How extreme does Park Ridge's weather get?

The hottest, coldest, wettest and snowiest days Park Ridge 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 Chicago Ohare Intl Ap station 9 km away. Updated through May 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 Park Ridge has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day

104°F Jun 20, 1988

That is about 24°F hotter than a normal June afternoon in Park Ridge (typical high near 80°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.

Park Ridge's record heat sits well above even a hot day for the season — June's 104°F is about 24°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, Park Ridge's warmest days reach the mid-80s°F and its coldest nights drop to the high 10s°F. But across the record it has gone as high as 104°F and as low as −27°F. A single day has delivered over 7 inches of rain or close to 19 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
