About Tornadoes in Windsor

This overview was written April 23, 2026. The tornado counts and notable-event figures elsewhere on this page reflect the latest data and may differ from this summary.

Windsor, Colorado and the surrounding 25-mile area have experienced 160 documented tornadoes since 1950, according to the NOAA Storm Prediction Center. This substantial tornado activity reflects the region's position along Colorado's Front Range, where colliding air masses from the mountains and plains create favorable conditions for severe thunderstorm development during spring and early summer months.

Tornado frequency in the Windsor area has varied considerably by decade. The 1990s saw the highest activity with 39 recorded tornadoes, followed by 34 in the 1980s and 21 in the 1970s. More recent decades have shown lower counts, with 19 tornadoes in the 2000s, 12 in the 2010s, and 9 thus far in the 2020s. May stands out as the peak month for tornado occurrence, accounting for 49 events—nearly one-third of the historical total. This seasonal pattern aligns with typical severe weather dynamics across the central United States, when warm, moist air from the Gulf of Mexico meets cooler, drier air aloft.

The vast majority of tornadoes near Windsor have been relatively weak on the Enhanced Fujita scale, which rates tornado intensity from EF0 to EF5 based on damage indicators. Of the 160 recorded events, 86 were rated EF0 and 59 were rated EF1, meaning they caused light to moderate damage. Only 10 tornadoes reached EF2 intensity, and just 3 achieved EF3 status. Two tornadoes remain unrated in the historical record.

The most significant tornado in the area's recorded history occurred on May 22, 2008, when an EF3 tornado carved a 38.7-mile path with a maximum width of 1,760 yards. This event caused one fatality and approximately $147 million in property damage, making it simultaneously the deadliest, costliest, widest, and longest-tracked tornado on record for the Windsor vicinity. The most recent tornado occurred on June 20, 2024—an unrated event with a brief 0.1-mile path, 20-yard width, and no reported damage or casualties.
