Top State & County by Flash Density: Oklahoma claimed the top position with 73 flashes per square mile, Kay County, Oklahoma, led the nation with 123.4 flashes per square mile. Florida is frequently the dominating state in this category, however the lack of landfalling tropical systems during 2025's hurricane season likely lessened that number. Louisiana and Kansas rounded out the top four.
Peak Lightning Day: June 15 saw the most of any day of the year with 929,016 flashes.
Tourist and Travel Impacts: Hartsfield-Jackson International Airport in Atlanta reported 10,000 lightning flashes. ATL, along with several other of the busiest airports in the county saw peak lightning numbers during the summer and the peak travel season. Millennium Park in downtown Chicago recorded more than 11,000 lightning flashes. Three SEC stadiums made up the greatest lightning exposure, Tiger Stadium, Kyle Field, and the Cotton Bowl.
Active Great Plains: 2025 signaled a shift to more frequent lightning in the heart of the country. While Oklahoma saw the highest flash density, Texas reported the most overall flashes at 13 million. That's 1.3 million more than average for the Lone Star State. About half of the top ten lightning states in 2025 were in the Great Plains. This is due in part to major severe weather outbreaks on the billion dollar disaster scale.
