The 1910s Pacific hurricane seasons all began on May 15 of their respective years in the eastern north Pacific Ocean and on June 1 in the central north Pacific. They ended on November 30 of each year. These dates conventionally delimit the time of year when most tropical cyclones form in northeast Pacific Ocean tropical cyclone basin, between the International Date Line and the west coast of North America. However, tropical cyclone formation is possible at any time of the year. Before the dawn of the satellite era in the 1960s, data on Pacific hurricanes is extremely unreliable. For a few years, there are no reported cyclones, although many systems likely formed and went undocumented.
