Indianapolis, IN – December wrapped up colder and snowier than usual in Indianapolis, marking the city’s coldest December in seven years and delivering one of the highest snowfall totals the metro has seen in more than a decade.
According to the National Weather Service Indianapolis, the city’s average temperature for December settled at 32.1 degrees, which is 1.2 degrees below normal. That made December 2025 the coldest since 2017, when average temperatures dropped to 30.2 degrees.
Daytime highs averaged 39.8 degrees, running 0.6 degrees below normal, while overnight lows averaged 24.5 degrees, or 1.7 degrees colder than typical for the month. Residents across Marion County and the greater Indianapolis metro felt the extended cold through multiple freezing mornings and brisk afternoons.
Snowfall stood out even more. Indianapolis recorded 11.8 inches of snow in December, making it the snowiest December since 2012 and the 13th highest December snowfall on record for the city. The total came in 5.4 inches above normal, contributing to hazardous travel conditions on several days throughout central Indiana.
Precipitation overall was lighter than usual despite the snow, with December totaling 2.39 inches, or 0.53 inches below normal, according to weather officials.
The combination of colder temperatures and above-average snowfall led to increased salt use, slick road conditions, and higher heating demand across Indianapolis and surrounding communities.
With winter officially underway, forecasters remind residents to stay alert for changing conditions as January progresses, historically one of the coldest months of the year in Indiana.
