The 1955 Pacific typhoon season has no official bounds; it ran year-round in 1955, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The season produced a large number of tropical storms but most of them were weak, and sources from American typhoon warning agencies often grossly overestimated the maximum wind speed of many systems which could not properly match with their respective central pressure observations.
The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1955 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Fleet Weather Center on Guam.
