1942–1948 Pacific hurricane seasons

The 1942–48 Pacific hurricane seasons all began during late spring in the northeast Pacific Ocean and the central Pacific. They ended in late fall.

Before the satellite age started in the 1960s, data on east Pacific hurricanes is extremely unreliable. In a few years, there are no reported cyclones although many systems certainly formed.
