A new analysis of Indianapolis weather data over the past 30 years reveals that snowfall is common after the first 70-degree day of the year in the city. While 16 of those years saw no additional measurable snow, 10 years recorded at least an inch, and 4 years saw 8 inches or more of snow following the initial warm spell.

Why it matters

Indianapolis residents are often surprised when a warm start to spring is followed by a late-season snowfall. This data provides helpful context around how frequently this weather pattern occurs, allowing the public to be better prepared for potential winter weather even after the first signs of spring.

The details

The analysis looked at Indianapolis weather records dating back to the 1880s. On January 20, 1906, the city hit 70 degrees unusually early, and that year ended up seeing the most snowfall after the initial warm day, with 36.7 inches, the bulk of which fell in March. Overall, the average first 70-degree day in Indianapolis over the past 30 years has been March 12.

  • On January 20, 1906, Indianapolis hit 70 degrees.
  • In 2026, Indianapolis hit 70 degrees for the first time about a week ago.
