There’s one winter day that still lives rent-free in local memory. It wasn’t just cold, it was the kind of cold that shut everything down, made schools close, and turned stepping outside into a bad decision almost instantly.

That day wouldn’t just be uncomfortable. It would end up rewriting Rockford’s weather record books.

When the Thermometer Bottomed Out

On January 31, 2019, temperatures in Rockford plunged to -31°F, the coldest day ever recorded in the city. The previous record, set back in 1982 at -27°F, stood for decades before finally being broken. During that 2019 Polar Vortex, wind chills dipped close to -57°F, making even short trips outside dangerous.

This Wasn’t a One-Time Fluke

Rockford has a long history of extreme cold. Multiple mornings in the 1980s saw temperatures in the mid-20s below zero. Even earlier, January 1912 holds the record for the city’s coldest average month, barely cracking 5°F.
