We know the question on your mind, Hoosiers — when’s it going to get cool again?
Thanks to the National Oceanic and Atmospheric Administration’s Climate Prediction Center, we know what temperatures and precipitation trends to expect for September, October, and November.
While exact weather conditions typically can’t be predicted more than a week in advance, here’s a seasonal outlook to help you prepare for what fall will bring.
Reminder: The first day of fall is on Sunday, Sept. 22.
🌡️ Temperature
Think above average. This fall, Indy has 40-50% chance of temperatures being higher than normal.
🌨️ Precipitation
Expect average precipitation. Indy has an equal chance of seeing above or below normal rainfall amounts this fall.
☀️ Drought
Drought conditions are likely to develop for much of central Indiana this season.
September
September typically brings a welcoming transition from the heat of summer to the cool of autumn in Indy. While temperatures historically remain high at about 75.9°F, there’s a decrease towards the end of the month — although we’ve felt an up and down jump in temperatures so far this month.
You’ll also notice the city gets darker earlier as the days shorten, bringing a clear change in pace from the lingering summer daylight — a good reminder to start cozying up indoors or gathering around a bonfire.
October
For some of us, October is the official start of fall because it typically carries the essence of autumn + you really start to see and feel the temperature change — an intermediate period between the warm summer and brisk winter. As temperatures moderate, falling to an average low of 47.3°F, we’ll get a refreshing chill after a very hot summer.
November
Make sure you dress in layers. Indy in November usually brings a significant drop in temperature, bracing for the upcoming winter. With the mercury dropping to an average low of 36.1°F, the city dons its winter attire + a sense of anticipation for the impending holiday season.
