BREAKING: A new report confirms that Oklahoma was the lightning capital of the U.S. in 2025 – not Florida! The data comes from AEM, an environmental monitoring/consulting group. Oklahoma averaged 73 flashes per square mile. Kay County was also the most lightning-prone county in the U.S., with 123.4 flashes per square mile. Oklahoma saw lots of MCSs, or mesoscale convective systems – large-scale sprawling thunderstorm complexes and squall lines. Because they're horizontally expansive, they have extensive electric fields that produce prolific lightning. After Oklahoma, Florida came in second place. Then Louisiana, and then Texas – in terms of density. Texas, meanwhile, had about 13 million strikes. That's the greatest *tally*, but not the greatest *density*.
