Before the satellite age started in the 1960s, data on east Pacific hurricanes was extremely unreliable. Most east Pacific storms were of no threat to land. However, 1939 saw a large number of storms threaten California. Systems Hurricane One On June 12, a hurricane was detected. The lowest pressure reported by a ship was 985 mbar inHg on.

Tropical Cyclone Eight On September 5, a tropical cyclone formed off the coast of Costa Rica. It also headed northwest and dissipated over the southern part of Baja California on September 15. The lowest reported pressure was 1004 mbar inHg on. From September 19 to 21, remnants of this tropical cyclone caused rain measuring up to 3 in mm in Southern California. Hurricane Nine 1939 California tropical storm thumb|Map showing effects of Hurricane Nine on California On September 14, a tropical cyclone formed off the coast of Central America. This tropical storm tracked northwestward and intensified into a hurricane. The sea-level pressure dropped to 975 mbar inHg on or lower. The hurricane recurved gradually to the northeast and weakened over cool seas. On September 25, this tropical storm made landfall near Long Beach, California, and dissipated inland. The tropical storm caught Southern Californians unprepared. It brought heavy rain and flooding to the area, which killed 45 people. At sea, 48 were killed. The storm caused heavy property damage amounting to $2 million (1939 USD) in total, mostly to crops and coastal infrastructure. Hurricane Ten thumb|Surface analysis of Hurricane Ten making landfall on October 25 On October 23, a tropical cyclone formed south of Cabo Corrientes, Jalisco. It intensified and headed roughly due north. A steamer, the Nevadan, caught in the eye of this extremely intense hurricane, recording a corrected central pressure of 930 mbar (hPa; 27.46 inHg).Monthly Weather Review Willis Hurd Additional Note on the Mexican West Coast Cyclone of October 23–25, 1939 1940 68 1 29 10.1175/1520-0493(1940)068<0029:ANOTMW>2.0.CO;2 1940MWRv...68Q..29H http://docs.lib.noaa.gov/rescue/mwr/068/mwr-068-01-0029b.pdf 2011-01-18 2012-06-12 https://web.archive.org/web/20120612113540/http://docs.lib.noaa.gov/rescue/mwr/068/mwr-068-01-0029b.pdf live Even with modern tropical cyclone observation techniques available, this reading still qualifies this cyclone as one of the most intense on record and would likely have made it a Category 4 or 5 hurricane. The steep pressure gradient between the Nevadan and the external hurricane conditions off of Manzanillo, Colima caused several tarpaulins to burst. Other shipping was disrupted off the Mexican coast by the intense tropical cyclone. The hurricane made landfall near Cabo Corrientes on October 25 and dissipated shortly thereafter.North Pacific Ocean, October 1939 Monthly Weather Review 2011-01-18 Willis Hurd June 1939 67 10 406 10.1175/1520-0493(1939)67<406:NPOO>2.0.CO;2 1939MWRv...67..406H http://docs.lib.noaa.gov/rescue/mwr/067/mwr-067-10-0406b.pdf 2012-02-05 https://web.archive.org/web/20120205130653/http://docs.lib.noaa.gov/rescue/mwr/067/mwr-067-10-0406b.pdf live Onshore, the storm caused an extensive swath of damage.
