Upland sits at the foot of the San Gabriel Mountains in southwestern San Bernardino County, on the western edge of California's Inland Empire. Tornado activity in this corner of Southern California is tied to the cool season, when Pacific storm systems push cold, unstable air across the inland valleys, and Upland's history follows that pattern closely, with events clustering from December through March.
An F1 tornado struck the area on November 25, 1965, and another F1 was recorded on March 16, 1986. A burst of cool-season activity arrived between 1991 and 1993: F0 tornadoes touched down on March 20, 1991, an F1 followed on December 7, 1992, and another F1 hit on January 14, 1993, with an F0 close behind on February 8, 1993. Warm-season events are less common here, though an F0 was recorded on September 7, 1976, and another on August 14, 2004.
Recent activity has stayed true to the winter pattern: an EF0 tornado was recorded near the city on February 23, 2023, and another EF0 touched down on March 13, 2025, both cool-season events of the kind Upland has seen for decades.
