Indiana Climate – June 2026 Update
Top 5 Cities: Indianapolis, Fort Wayne, Evansville, South Bend, and Carmel
This month in numbers
Indiana experienced its 8th warmest April–June period on record, with an average temperature of 17.41°C, a significant 1.4°C above the 1961–1990 baseline. This spring also saw the 8th wettest April–June on record, with 141.9 mm of precipitation, an increase of 41.6 mm compared to the baseline. Globally, June 2026 was the 3rd warmest June on record for land temperatures, and the April–June period ranked as the 2nd warmest for global land temperatures.
What changed
The past three months in Indiana have been notably warmer and wetter than average. While June's average temperature was only slightly above the baseline, the preceding months of April and May contributed to the significantly warmer seasonal trend. This regional warming aligns with the broader national and global picture, as global land temperatures also show a strong warming trend, with the past three months ranking as the 2nd warmest on record globally. Indiana's 1-month anomaly of +0.10°C places it 217th out of 234 regions globally for the latest month, indicating that while it was warmer than average, many other regions experienced far more significant warming.
What’s driving change?
The warmer temperatures in Indiana are part of a broader trend of seasonal shifts, with winters warming faster than summers at high latitudes. The region also experienced significant extreme weather events in June. There were four wildfire events between June 27 and July 13, representing 100% of the annual total for Indiana, which is an unusual concentration. Additionally, one flood event occurred between May 19 and July 12, also accounting for 100% of the annual total for the state. Multiple rounds of heavy rainfall in June led to considerable flash flooding across west-central and southern Indiana, with some areas receiving 4 to 8 inches of rain, and isolated amounts up to 10 to 12 inches, in a 72-hour period. This amount of rain has a return interval of about 200 years for some locations. You can track active extreme weather events at Extreme Weather tracker.
Looking ahead
The NOAA Climate Prediction Center's 3-month outlook for July-August-September 2026 suggests an increased likelihood of above-normal temperatures for Indiana.
