Vacaville, California, has experienced eight tornadoes within a 25-mile radius since 1950, according to the NOAA Storm Prediction Center. All eight events have been rated EF0, the weakest classification on the Enhanced Fujita scale, which measures tornado intensity based on damage to structures and vegetation. None of these tornadoes resulted in fatalities, reflecting both their limited strength and the relatively low frequency of severe tornado activity in this part of Northern California.
Tornado activity near Vacaville has been sporadic across the decades. A single tornado occurred in the 1980s, followed by two in the 1990s and one in the 2000s. The most active period came in the 2010s, when four tornadoes were recorded. April has been the peak month for tornado occurrence, with two events documented during that month. While spring tornadoes are common nationally due to the collision of warm, moist air with cooler systems, the modest number of events near Vacaville suggests that conditions favorable for tornado formation occur infrequently in this region.
The costliest tornado on record touched down on April 7, 2011, causing $26,000 in property damage along a 0.1-mile path with a maximum width of 10 yards. The widest tornado occurred on March 1, 2014, reaching 50 yards across during its 0.7-mile track, though it caused no reported damage. The longest-tracked tornado, and also the most recent, occurred on September 29, 2019, traveling 1.7 miles with a maximum width of just one yard and resulting in no damage or injuries.
The EF0 rating assigned to all tornadoes near Vacaville indicates wind speeds between 65 and 85 miles per hour—strong enough to damage roofs, break tree branches, and overturn lightweight structures, but far less destructive than the violent tornadoes that occur in other parts of the United States. The narrow path widths and short distances traveled by these storms further limited their impact on the community.
