Typhoon Ora first developed as an weak circulation on August 9th. The influence of a nearby upper-level trough allowed it to intensify from a depression to a Category 1 typhoon in 30 hours.

It moved along the entire length of Japan, weakening to a depression. Rita strengthened back into a tropical storm over the Kuril Islands— an unusually northerly location— before dissipating on August 24. At least 26 deaths can be attributed to this typhoon from the heavy flooding— the worst in 10 years.

Western North Pacific tropical cyclones were named by the Joint Typhoon Warning Center. The first storm of 1975 was named Lola and the final one was named June.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 6 of which are published each year before the season starts. Names not retired from this list will be used again in the 1979 season. This is the same list used for the 1971 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in gray.
