The 1963 Pacific typhoon season has no official bounds; it ran year-round in 1963, 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 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 1963 Pacific hurricane season. 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. This was the first season in which PAGASA assigned local names to typhoons. Systems 36 tropical depressions formed this year in the Western Pacific, of which 25 became tropical storms. 19 storms reached typhoon intensity, of which 8 reached super typhoon strength. Tropical Depression 03W A brief tropical depression developed north of Papua New Guinea at 00:00 UTC on March 25, and tracked west-northwest before it dissipated later that day. Although the Joint Typhoon Warning Center does not list any maximum sustained wind values in its tracking data, the Mariners Weather Log notes that Tropical Depression 03W briefly attained winds of at its peak before dissipating. CMA Tropical Depression 1 The China Meteorological Administration (CMA) analyzed the formation of a disturbance near Micronesia on March 30, though no other agencies monitored the system. Tracking westward, the low-pressure area developed further into a tropical depression the following day. The storm turned towards the north on April 1, reaching peak intensity two days later with winds of 55 km/h and a minimum pressure of 1001 mbar (hPa; ) before slowly weakening. On April 6, the depression degenerated into a remnant area of low pressure; these remnants tracked westward before dissipating early the next day. Typhoon Olive The low-pressure area that eventually developed into Typhoon Olive first formed approximately southeast of Truk on April 21, embedded within the larger context of a trough. In its nascent stages, the disturbance tracked slowly
