The 1980 Pacific typhoon season has no official bounds; it ran year-round in 1980, 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 which formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. 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.

A total of 28 tropical depressions formed this year in the Western Pacific, of which 24 became tropical storms. Beginning in March, tropical cyclones formed in each subsequent month through December. Of the 28, 15 storms reached typhoon intensity, of which 2 reached super typhoon strength. Seven tropical cyclones moved through the Philippines this season.

Tropical Depression Asiang

Tropical Depression 01W (Biring)

Severe Tropical Storm Carmen

Tropical storm (SSHWS)

Duration	April 5 (entered basin) – April 7 (exited basin)
Peak intensity	110 km/h (70 mph) (10-min); 985 hPa (mbar)

On April 4, a tropical depression formed just east of the International Date Line.^[1] At the time, the Joint Typhoon Warning Center (JTWC) designated it tropical depression 02W. As it moved generally northwestwards, it strengthened into a tropical storm just before crossing the dateline, but only received a name in the northwest Pacific, being dasignated Carmen.^[1] After peaking with maximum sustained winds of 70 mph (110 km/h) on April 6. Carmen recurved northeast and crossed the International Date Line, entering the central Pacific on April 7.^[1] The JTWC subsequently relinquished responsibility to the Central Pacific Hurricane Center. Carmen lost its initial motion and stalled in the area, ultimately weakening in to a tropical depression on April 8.^[1] The depression dissipated the following day and the remnant low returned to western Pacific.^[1]

Very strong typhoon (JMA)
Category 3 typhoon (SSHWS)

Duration	July 16 – July 23
Peak intensity	155 km/h (100 mph) (10-min); 940 hPa (mbar)

115 mph Typhoon Joe, which developed on July 16 from the near equatorial trough, hit eastern Luzon on the 20th. It weakened over island, but restrengthened in the South China Sea to a 100 mph typhoon before making landfall on Hainan Island on the 22nd. Joe made its final landfall that night on northern Vietnam before dissipating on the 23rd. Joe caused heavy damage and an estimated 19 deaths in the Philippines with many more in Vietnam. The exact numbers are unknown due to Typhoon Kim hitting just four days later.

Tropical Depression Maring

Tropical depression (PAGASA)

Peak intensity	55 km/h (35 mph) (10-min);

Super Typhoon Kim (Osang)

Very strong typhoon (JMA)

Duration	July 19 – July 27
Peak intensity	185 km/h (115 mph) (10-min); 910 hPa (mbar)

Like Joe, Kim formed from the near equatorial trough on July 19. It tracked quickly westward, reaching tropical storm strength on the 21st and typhoon strength on the 23rd. Kim rapidly intensified on the 24th to a 150 mph Super Typhoon, but its inflow was cut off by the Philippines to the southwest. The typhoon weakened to 115 mph winds just before hitting eastern Luzon on the 25th, just days after Joe and a tropical depression hit the same area. Kim continued northwestward, but with its disrupted circulation, it remained a tropical storm until hitting southern China on the 27th, 90 miles northeast of Hong Kong. The typhoon brought torrential rains and massive flooding, causing only 15 deaths, moderate to heavy damage, and leaving hundreds of thousands homeless. The exact totals are unknown, due to Joe and a Tropical Depression just days before.

Typhoon (JMA)
Category 2 typhoon (SSHWS)

Duration	September 1 – September 11
Peak intensity	130 km/h (80 mph) (10-min); 960 hPa (mbar)

The monsoon trough spawned a tropical depression on September 1. It tracked northwestward, remaining disorganized and dissipating on the 5th. Another tropical depression developed to the east of the old circulation, quickly becoming the primary circulation and intensifying to a tropical storm on the 6th. With generally weak steering currents, Orchid looped three times on its track, strengthening to a typhoon on the 9th and reaching a peak of 95 mph winds on the 10th. Early on the 11th the storm hit southwestern Japan, and became extratropical that day over the Japan Sea. Orchid caused considerable damage from high winds and rain, resulting in at least nine casualties with 112 missing. It was also responsible for the September 10th loss of the MV Derbyshire, a large 91,655 ton bulk carrier lost with all 44 hands on board.

Typhoon Percy (Undang)

Very strong typhoon (JMA)
Category 4 typhoon (SSHWS)

Duration	September 13 – September 19
Peak intensity	185 km/h (115 mph) (10-min); 915 hPa (mbar)

140 mph Typhoon Percy brushed southern Taiwan on September 18. A day later, with its circulation and low-level inflow greatly disrupted, 50 mph Tropical Storm Percy hit southeastern China, and dissipated later that night. 7 people died in the storm, with moderate damage on its path.

Severe Tropical Storm Ruth

Severe tropical storm (JMA)
Category 1 typhoon (SSHWS)

Duration	September 13 – September 16
Peak intensity	100 km/h (65 mph) (10-min); 980 hPa (mbar)

A monsoon depression transitioned into a tropical depression on September 13 in the South China Sea. It initially moved southward, then turned to the west-northwest, reaching tropical storm strength late on the 13th. Ruth crossed Hainan Island on the 14th and 15th, becoming a typhoon late on the 15th before hitting northern Vietnam on the 16th. The typhoon left nearly half a million homeless, with 106 known dead or missing in Vietnam.

Storm names

During the season 24 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list which started on 1979.

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 1984 season. This is the same list used for the 1976 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.
