List of California hurricanes

Since 1854, at least 100 tropical cyclones affected the U.S. state of California, including a hurricane in 1858 that produced hurricane-force winds near San Diego.

Tropical Storm Nora in 1997 entered the state, producing gale-force winds and heavy rainfall that led to four traffic deaths.

The remnants of Hurricane Kay in 2022 produced flooding and 100 mph (160 km/h) wind gusts across southern California, killing one person.

As a result, the temperatures in the summer rarely rise above 24 °C (75 °F) in southern California, too cold to sustain intense tropical cyclones, and much cooler than the same latitude along the United States Atlantic coastline.

[3][4] Although tropical cyclones have affected the state between June and October, September is the month with the most events, which is when storms can be drawn northward by strong upper-level troughs.

After the unexpected 1939 Long Beach tropical storm, the weather bureau set up a forecast office for southern California in February 1940.

The NHC can issue these advisories at one of seven locations along the Pacific coast, known as breakpoints, beginning at the Mexico–United States border, and continuing northward to Point Piedras Blancas.
