Moraga, California has experienced 10 documented tornadoes within a 25-mile radius since 1950, according to NOAA Storm Prediction Center records. This relatively modest total reflects the region's location along the Pacific Coast, where tornadoes are far less common than in the central United States due to different atmospheric dynamics and moisture patterns.
All recorded tornadoes in the area have been rated EF0 or EF1 on the Enhanced Fujita scale, with seven EF0 events and three EF1 events. The Enhanced Fujita scale measures tornado intensity based on damage indicators, with EF0 representing wind speeds of 65–85 mph and EF1 representing 86–110 mph. Notably, none of the tornadoes on record resulted in any fatalities, and property damage has generally been minimal. The costliest event occurred on April 25, 1994, when an F0 tornado caused $27,500 in property damage along a 0.7-mile path with a maximum width of 30 yards.
Tornado activity in the Moraga area has been sporadic across the decades, with the 1990s seeing the most events at four tornadoes, followed by three in the 1980s. The 1950s, 2000s, and 2010s each recorded one tornado. March has been the peak month for tornado occurrence with two events, though tornadoes have touched down in various months including January, April, and December. The most recent tornado struck on January 23, 2010, rated EF1 with a 1.6-mile path length and causing $25,000 in damage.
The longest-tracked tornado on record traveled 3.0 miles on March 20, 2005, while the widest reached 150 yards across during a December 6, 1998 event that caused no property damage. These relatively short path lengths and narrow widths are characteristic of the weaker tornadoes that typically form in California's coastal regions, where conditions for sustained tornadic development are less favorable than in areas with greater atmospheric instability and wind shear.
