The 1951 Pacific typhoon season was a generally average season with multiple tropical cyclones striking the Philippines. With the exception of January, each month saw at least one tropical system develop; October was the most active month with four tropical cyclones forming. Overall, there were 31 tropical depressions, of which 25 became tropical storms; of those, there were 16 typhoons.
The season began with the formation of a short-lived unnamed tropical storm on February 19, well east of the Philippines; Typhoon Georgia became the season's first named storm and typhoon after first developing in the open Pacific on March 20. In April, Typhoon Iris developed before intensifying into a super typhoon the following month; Iris was the first recorded instance of a Category 5-equivalent typhoon in the western Pacific. The final typhoon and storm of the year was Typhoon Babs, which remained at sea before dissipating on December 17.
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 1951 Pacific hurricane season. At the time, tropical storms that formed within this region of the western Pacific were named and identified by the Fleet Weather Center in Guam. However, the Japan Meteorological Agency (JMA), which was established five years later, identified four additional tropical cyclones during the season not tracked by the Fleet Weather Center; these analyzed systems did not receive names.
