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.
Systems
The rest of the storms, such as unnumbered and unnamed tropical depressions and storms, are only classified by the CMA while the JMA is sometimes rare before the 1960s - 1970s.

However, it weakened again on April 22 but again re-intensified to a category 1 and even a category 2 typhoon later. Anita reached its peak intensity as a category 3 typhoon. Anita encountered a strong wind shear and because of this, Anita rapidly weakened to a tropical storm. Anita weakened to a tropical depression on April 25. Later, Anita loses its identity and dissipated.

Super Typhoon Louise
WPac Louise 1955 path.png September 20 September 30 typhoon 150 930 Typhoon Louise at Kokura.JPG
Louise formed on September 20 as a weak tropical depression. It intensified into a tropical storm and even a typhoon later. Wind shear quickly decreased and sea surface temperatures began to rise and Louise rapidly intensified into a category 5 super typhoon. However, the process of eyewall replacement cycle caused Louise to weaken. Louise weakened to a category 2 typhoon and it started to affect the Kyūshū island of Japan and even weakened to a category 1 typhoon and affected Japan. Louise dissipated on September 30. On Kyūshū island, 31 people were killed, 41 went missing, 241 injured and 197,429 persons affected either through loss of homes or flooding. Total property damage was estimated as approaching $30,000,000.
A disastrous by-product of the storm was the fire that swept through the business district of the Honshu seaport city of Niigata on the morning of October 2. More than 1,100 buildings were burned when strong winds whipped what would have been a minor fire across the city. There was no loss of life, however. United States Air Force personnel from their base outside the city joined in aiding victims of the fire.1955-10-02 TYPHOON LOUISE DIES IN NORTHERN JAPAN https://www.nytimes.com/1955/10/02/archives/typhoon-louise-dies-in-northern-japan.html 2025-07-15 The New York Times en-US 0362-4331

Super Typhoon Ruth
WPac Ruth 1955 track.png December 12 December 18 typhoon 180 888
Typhoon Ruth was one of the strongest storms on record reaching 180 kts (205 mph) sustained winds measured by a reconnaissance aircraft.Joint Typhoon Warning Center (JTWC) https://www.metoc.navy.mil/jtwc/jtwc.html?western-pacific 2025-07-15 www.metoc.navy.mil 2019-10-02 https://web.archive.org/web/20191002131144/https://www.metoc.navy.mil/jtwc/jtwc.html?western-pacific dead However, it was later determined that measurements and estimates from the 1940s to 1960s were erroneous. Thus, Ruth's measurement may likely be lower than the official best-track values.
Storm names
The names came from a series of four rotating lists. Names were used one after the other without regard to year, and when the bottom of one list was reached, the next named storm received the name at the top of the next list. The names Violet, Wilda, Dot, and Patsy were used for the first time this season.
