| Kansas Tornado Climatology & Statistics |
Most of the charts on this webpage were compiled with data from the Storm Prediction Center and the National Centers for Environmental Prediction.
| Annual State Tornadoes | Annual State Tornadoes Per 10K Square Miles |
 |
 |
| Average annual number of tornadoes per state between 1994 and 2023. Kansas averages 81 tornadoes per year, 2nd only to Texas who averages 135 per year. | Average annual number of tornadoes per 10,000 square miles per state between 2004 and 2023. Kansas averages 10 tornadoes per 10,000 square miles per year, which is tied for 3rd place with Iowa and Illinois. |
| Annual Kansas Tornadoes | Annual Kansas Tornadoes (F/EF 1-5) |
|
|
|
| Annual number of tornadoes across Kansas between 1950 and 2023. The apparent increase in annual tornadoes during the 1980s and 90s is likely due to the introduction of the WSR-88D radar, and thus better tornado detection, along with a denser spotter/chaser network, and more robust reporting. In recent years, atmospheric conditions supporting tornadoes have not been as prevalent across the state, hence the decreasing trend in the number of tornadoes since roughly the early 2010s. | Annual number of tornadoes (excluding F/EF0s) across Kansas between 1950 and 2023. Excluding EF0s gives a more accurate trend of tornadoes over time, since EF0s were not reported as vigorously in the distant past. The data indicates an overall decreasing trend in the number of EF1-5 tornadoes across the state since roughly the early 2010s. |
| Kansas Strong to Violent Tornadoes | Kansas Tornado Days |
|
|
|
| Annual number of strong to violent (F/EF 3-5) tornadoes across Kansas between 1950 and 2023. The data indicates an overall decreasing trend in the number of strong to violent tornadoes across the state since roughly the mid to late 2010s. In fact, since 2020 across Kansas, it has been one of the quietest periods with regard to strong-violent tornadoes on record. | Annual number of days that at least one tornado was reported across Kansas between 1950 and 2023. Since roughly the early 2010s, there has been a slight decreasing trend in the annual number of tornado days across the state. |
| Kansas Tornadoes by Intensity | Kansas Tornadoes Per County |
|
|
|
| Total number of tornadoes across Kansas between 1950 and 2023 separated by F/EF scale. Fortunately, over 90% of all tornadoes across the state have been F/EF 0-2, with around 5% considered strong-violent (F/EF 3-5). EFU tornadoes (unknown magnitude) have accounted for about 2% of all tornadoes across the state. | Total number of reported tornadoes per county between 1950 and 2023 across Kansas. The greatest is 113 tornadoes in Ford county, and the least is 11 tornadoes in Wyandotte county. |
| Kansas Monthly Tornadoes | Kansas Hourly Tornadoes |
|
|
|
| Average annual number of tornadoes per month across Kansas between 1950 and 2023. The peak months are typically April through June, which historically accounts for about 74% of annual tornadoes across the state. | Average annual number of tornadoes per time of day across Kansas between 1950 and 2023. The peak times are typically between 2-10 PM CST, and historically accounts for about 85% of annual tornadoes across the state. |
| Kansas Tornado Injuries | Kansas Tornado Fatalities |
|
|
|
| Total number of Kansas tornado injuries between 1950 and 2023 separated by F/EF scale. F/EF 3-5 tornadoes have been responsible for roughly 85% of all Kansas tornado injures, but account for only about 5% of all Kansas tornadoes. | Total number of Kansas tornado fatalities between 1950 and 2023 separated by F/EF scale. F/EF 3-5 tornadoes have been responsible for roughly 87% of all Kansas tornado fatalities, but account for only about 5% of all Kansas tornadoes. |
| Kansas Tornadoes Path Width | Kansas Tornadoes Path Length |
|
|
|
| Average path width (yards) of Kansas tornadoes between 1950 and 2023 separated by F/EF scale. While there are definitely exceptions, unfortunately the most violent tornadoes are often times the widest. | Average path length (miles) of Kansas tornadoes between 1950 and 2023 separated by F/EF scale. While there are definitely exceptions, unfortunately the most violent tornadoes often times have the longest tracks. |
