The first average snowfall in Indiana

INDIANA — Indiana’s winters can be unpredictable, but historical weather data offers a clear picture of when residents typically see the first snowflakes of the season.

On average, the state’s first measurable snowfall occurs in late November, though the timing varies widely depending on location and year.

Northern Indiana, influenced by both colder air from the Great Lakes and lake-effect snow, generally sees snow earlier than the rest of the state.

Cities such as South Bend and Fort Wayne often record their first measurable snowfall in early to mid-November. In some years, snow has arrived as early as late October, especially when cold fronts sweep in from Canada.

Central Indiana, including Indianapolis, usually experiences its first measurable snow around the last week of November into early December.

Historical records from the National Weather Service show that Indianapolis’ average first measurable snowfall falls close to November 21, though it has occurred as early as October and as late as December in past decades.

Southern Indiana, where the Ohio River valley and warmer air masses delay wintry conditions, typically sees the first measurable snow later.

Cities such as Evansville and Bloomington average their first snowfall in early to mid-December, though November snow is not unheard of during colder years.

While these averages provide a general timeline, Indiana’s first snowfall is far from predictable. Some winters bring an early dusting that melts quickly, while others delay significant snow until well into December.

Still, the historical record shows that by Thanksgiving, much of the state has at least a chance of seeing its first measurable snowfall.
