The US Lightning Capital Is Now Oklahoma, Depending on Who's Counting

In 2025, Oklahoma took the title of US lightning capital in one major report. AEM, which runs the Earth Networks lightning network, measured about 73 flashes per square mile in Oklahoma against 72.9 in Florida (AEM). Vaisala’s 2025 report, from a different detection network, still ranks Florida first for density, with Oklahoma second. But it named Shady Grove, Oklahoma as the single most lightning-dense place in the country (Vaisala). Texas, meanwhile, recorded the most lightning in total in both reports.

So the honest answer to “which state has the most lightning strikes” depends on what you measure. Here’s how to read the numbers, and why they matter if you own a building in Oklahoma, Texas or Colorado.

Two reports, two answers

Both reports came out on January 5, 2026, and both are built on national lightning detection networks. They count different things.

	AEM (Earth Networks) 2025	Vaisala Xweather 2025
Unit	Lightning flashes	Lightning events
US total	88.4 million flashes (about 430 million pulses), up 9.8%	252 million events, up 20%
Top state for density	Oklahoma, about 73 flashes/sq mi	Florida, 305 events/sq mi
Florida / Oklahoma	Florida 72.9 flashes/sq mi	Oklahoma 253 events/sq mi
Hottest local spot	Kay County, OK: 123.4 flashes/sq mi	Shady Grove, OK: 3,005 events/sq mi
Texas	More than 13 million flashes, 1.3 million above its average	47 million events, most of any state

Sources: AEM report, AEM press release, Vaisala.

A flash is a whole lightning discharge, which can contain several strokes and pulses. That’s why Vaisala’s “event” counts run several times higher than AEM’s “flash” counts. Don’t compare a number from one report with a number from the other. Compare rankings within each report.

Read that way, both reports agree on the big picture. Oklahoma and Florida are neck and neck for density, and in AEM’s data the gap was a tenth of a flash per square mile. Oklahoma has the hottest single spot in both. Texas gets the most lightning overall because it’s so big. Vaisala notes that once you adjust for area, Texas drops out of the top five for density.

Why Oklahoma pulled even with Florida in 2025

AEM’s lightning scientist put it down to the weather pattern: Florida had a drier year, with most Atlantic hurricanes staying away from the US, while Oklahoma had an active severe-weather season (AEM press release). AEM also reported that the six core Great Plains states produced more than a third of all US lightning flashes in 2025, about 2.6 million above their four-year average (AEM).

Vaisala noted that the year’s busiest single day came early. On April 5, 2025, storms produced more than 3 million lightning events in the contiguous US, weeks ahead of the usual May-to-September season (Vaisala).

One year doesn’t make a trend. AEM itself describes Florida as the state that has traditionally dominated the ranking, and with a margin this thin it could easily be back on top in 2026.

Texas: the most lightning, and the most expensive

Texas leads on total volume. AEM also ranked it first for storm intensity, with 9,103 Dangerous Thunderstorm Alerts in 2025, more than twice as many as the next state (Oklahoma) (AEM). Dallas–Fort Worth International logged 17,754 flashes in 2025, more than Atlanta or Chicago O’Hare among the nation’s busiest airports.

The insurance numbers follow. Texas was third in homeowners lightning claims in 2025 with 4,188, but its average claim was $60,382, the highest of the top ten states, for total losses of about $252.9 million (III).

Colorado: fewer flashes, more deaths

Colorado doesn’t show up near the top of the density charts, and it’s a mistake to read that as low risk. NWS Pueblo’s figures (NWS Pueblo):

• Colorado ranks 19th in the nation for cloud-to-ground flashes and 32nd for flash density (2009–2018), averaging 4.8 flashes per square kilometer.
• About 500,000 lightning flashes strike the ground in Colorado in an average year.
• Colorado ranks 3rd in lightning deaths for 2006–2024. Only Texas and Florida had more.
• Since 1980, lightning has caused an average of 2 deaths and 12 injuries a year in Colorado, and El Paso County has the most casualties.

Our read of the gap between flash rank and death rank is exposure: much of Colorado is high, open country where people hike, ranch and work outdoors during summer storms. Denver International still logged 6,039 flashes in 2025 (AEM).

Density vs total vs deaths in one table

State	Density rank 2025	Total lightning	Lightning deaths	Lightning claims (2025)
Oklahoma	1st (AEM), 2nd (Vaisala)	Not a top-ten claims state	Not reported in these sources	Not in top 10
Florida	2nd (AEM), 1st (Vaisala)	Not reported in these sources	Most fatalities (III)	1st by count (5,167)
Texas	Outside Vaisala’s top 5	1st in both reports	Top two, 2006–2024 (NWS Pueblo)	3rd by count; highest average ($60,382)
Colorado	32nd (NWS, 2009–2018)	19th (NWS, 2009–2018)	3rd, 2006–2024 (NWS Pueblo)	Not in top 10

What about the lightning capital of the world?

Both companies also map global lightning, but the US title is what drives most searches. Vaisala’s network detected over 2 billion lightning events worldwide in 2025 (Vaisala). For the world’s top hot spots, see the global maps that come with each company’s report.

What the rankings mean for your building

State rankings are averages over huge areas. For any one building, local exposure matters more. The NWS says height, pointed shape and isolation decide where lightning strikes (NWS). A metal shop on open Oklahoma prairie, a tall warehouse in North Texas and a house on a Colorado ridgeline all stand out from their surroundings, whatever their state’s rank.

Some practical takeaways:

• Oklahoma and the southern Plains. Expect a long, active season. Ranches, barns and oil and gas sites are often the tallest thing for miles. Our article on tank battery lightning protection covers production sites.
• Texas. High volume and the highest average claim. Commercial buildings, churches, schools and warehouses carry a lot of value under one roof. See our commercial lightning protection page.
• Colorado. Don’t read a 32nd-place density rank as low risk. Elevation, open terrain and summer storms add up. Our post on commercial lightning protection for Colorado businesses goes further.
