The 1964 Pacific typhoon season was the most active tropical cyclone season recorded globally, with a total of 39 tropical storms forming. It had no official bounds; it ran year-round in 1964, 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.
Tropical Storms formed in the entire West Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
Notable storms include Typhoon Joan, which killed 7,000 people in Vietnam, mostly from catastrophic flooding; Typhoon Louise, which killed 570 people in the Philippines, Typhoons Sally and Opal, which both peaked at 1-minute sustained speeds of 195 mph, Typhoons Flossie and Betty, which both struck the city of Shanghai, China, and Typhoon Ruby, which hit Hong Kong as a powerful Category 4 storm, killing over 700 and becoming the second worst typhoon to affect Hong Kong.
