Top 5 Cities: Louisville, Lexington, Bowling Green, Owensboro, and Covington
This month in numbers
Kentucky experienced its 4th warmest April–June period on record, with an average temperature of 19.37°C, a significant 1.8°C above the 1961–1990 baseline. Maximum temperatures for the same three-month period also ranked 4th highest on record, at 25.91°C, which is 1.7°C above average. June 2026 itself saw above-average precipitation, ranking as the 8th wettest June on record with 157.73 mm, an anomaly of +57.6 mm. Globally, June 2026 was the 3rd warmest June on record for land temperatures, and the April–June period was the 2nd warmest on record for global land temperatures.
What changed
The past three months in Kentucky have been notably warmer than average, placing the region among the warmest on record for this period. This trend aligns with the broader national picture, as the contiguous United States also experienced above-average temperatures in June 2026. Kentucky's 3-month anomaly of +1.81°C places it 68th warmest out of 234 regions globally. The Ohio Valley US climate region, which includes Kentucky, also saw above-average temperatures, with Kentucky's June anomaly being 0.10°C warmer than the group average.
What’s driving change?
Kentucky experienced significant extreme weather events in June. Multiple rounds of storms between June 17th and 18th brought severe winds, tornadoes, and flash flooding to the region. Later in the month, from June 26th to 28th, additional severe storms resulted in widespread flash flooding across southern Indiana and central Kentucky, including an EF-0 tornado. These events led to fatalities and prompted Kentucky Governor Andy Beshear to declare a statewide state of emergency on June 27, 2026. The increased frequency and intensity of these rainfall events, coupled with warmer temperatures, are consistent with seasonal shifts and a warming climate.
Looking ahead
The ongoing warming trend suggests that Kentucky could continue to experience above-average temperatures in the coming months, with potential for further extreme weather events.

Shifting Seasons
Warm / cold seasonsKöppen Cfa · TemperateHow spring and autumn have shifted in Kentucky. Spring is defined as the date monthly temperatures first rise above the long-term annual mean (12.8°C, from 1950–1979); autumn is the date they fall back below it. Temperature swings 24.0°C peak-to-peak across the year - a classic four-seasons rhythm.
