Sioux Falls hail storm history
Minnehaha County·NOAA NCEI Storm Events Database·~75-day publication lag
Sioux Falls, located in Minnehaha County in eastern South Dakota, sits in a corridor where Gulf moisture, elevated terrain to the west, and the low-level jet converge to produce frequent hail storms. This geographic position makes the region one of South Dakota's more active hail zones, with documented hail events occurring regularly throughout the warm season.
Check if your roof was damaged by recent hail
Hail season in Sioux Falls peaks during June and July, with secondary activity in May and August. The peak arrives later in the season compared to the Southern Plains due to the higher latitude, as atmospheric conditions require more time to develop the instability and wind shear needed for severe hail production. Storms during these months can produce hail capable of causing functional damage to roofing and siding.
