The 1959 Pacific typhoon season was regarded as one of the most devastating years for Pacific typhoons on record, with China, Japan and South Korea sustaining catastrophic losses. It was an event in the annual cycle of tropical cyclone formation. The season had no official bounds, but tropical cyclones in the Western Pacific Ocean normally develop between May and October.
The 1966 Pacific typhoon season was an active season, with many tropical cyclones having severe impacts in China, Japan, and the Philippines. Overall, there were 49 tropical depressions declared officially or unofficially, of which 30 officially became named storms; of those, 20 reached typhoon status, while 3 further became super typhoons by having winds of at least 240 km/h (150 mph). Throughout the year, storms were responsible for at least 997 fatalities and $377.6 million in damage; however, a complete record of their effects is unavailable.
The 1953 Pacific typhoon season has no official bounds; it ran year-round in 1953, 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 1990–91 South-West Indian Ocean cyclone season was fairly quiet, although activity began early and the final named storm formed at a record late date. There were seven named storms classified by the Météo-France office (MFR) on Réunion, as well as three depressions; an additional depression was classified by the Joint Typhoon Warning Center (JTWC), an unofficial warning agency. The JTWC tracked storms in both September and October, although neither affected land. In late November, another short-lived depression formed in the northeastern portion of the basin. Activity remained minimal until January, when Tropical Storm Alison formed in the eastern portion of the basin. Later in the month, Cyclone Bella became the strongest storm of the season, reaching 10‑minute maximum sustained winds of 155 km/h (96 mph). It passed near the island of Rodrigues, becoming the worst cyclone there in 20 years and killing half of the population of one endangered species. Bella also likely caused a cargo ship to go missing with 36 people on board. Three storms developed in short succession in the second half of February. Cyclone Cynthia developed rapidly in the Mozambique Channel on February 16 and struck western Madagascar, killing 36 people and ruining local rice harvests. A residual trough after Cynthia dissipated spawned Tropical Storm Debra, which looped in the Mozambique Channel. Toward the end of the month, Tropical Storm Elma exited the basin into the adjacent Australian region, only to re-enter the south-west Indian Ocean and dissipate. Long-lived Cyclone Fatima originated in the Australian basin in late March and changed directions before becoming extratropical. On April 2, a tropical depression struck eastern Madagascar, killing 18 people. The final storm, Gritelle, was named on June 10, the latest on record.
The 1991–92 South-West Indian Ocean cyclone season was an average cyclone season in which most storms remained over open waters. At the time, the season's official bounds lasted from November 15, 1991, to April 30, 1992, although this season began early when three tropical depressions formed before the official start. The second, designated Tropical Depression A2 by the Météo-France office (MFR) on Réunion, passed north of Madagascar on October 16 before weakening.
The 1992–93 South-West Indian Ocean cyclone season lasted longer than normal, with the first storm Aviona forming on September 27 and the final storm Konita not dissipating until May 7. It was an above-average season, with four tropical cyclones – the equivalent of a minimal hurricane – along with six tropical storms, one subtropical depression, and several depressions including one that was named. The basin is defined as the area west of 90°E and south of the Equator in the Indian Ocean, which includes the waters around Madagascar westward to the east coast of Africa. Tropical cyclones in this basin are monitored by the Regional Specialised Meteorological Centre in Réunion (MFR), as well as by the Joint Typhoon Warning Center (JTWC).
The 1993–94 South-West Indian Ocean cyclone season was the most active season in the basin since the start of reliable satellite coverage in 1967, until the record was surpassed 25 years later in the 2018–19 South-West Indian Ocean cyclone season. Activity lasted from mid-November, when Moderate Tropical Storm Alexina formed, until mid-April, when Tropical Cyclone Odille became extratropical. Four tropical cyclones – Daisy, Geralda, Litanne, and Nadia – struck eastern Madagascar, of which Geralda was the costliest and deadliest. With gusts as strong as 350 km/h (215 mph) accompanied by heavy rainfall, Geralda destroyed more than 40,000 homes and left 356,000 people homeless. Geralda killed 231 people and caused more than $10 million in damage. Cyclone Nadia was the second deadliest cyclone, having killed 12 people in northern Madagascar and later severely damaging portions of northeastern Mozambique, killing about 240 people and leaving $20 million in damage in the latter country. In February, Cyclone Hollanda struck Mauritius near peak intensity, causing $135 million in damage and two deaths.
The 1994–95 South-West Indian Ocean cyclone season was fairly active, with storms forming regularly from October through April. It was much less damaging than its predecessor, and most of the storms in the season remained over water or only brushed land. The first system was Tropical Depression A1, which formed in October and passed north of Madagascar. The first named storm was Albertine, which formed on November 23 in the northeastern portion of the basin and became one of three intense tropical cyclones. The last storm was Marlene, which was also an intense tropical cyclone and dissipated on April 11.
The 1940 Pacific typhoon season marked an interruption in meteorological records in both the Philippines and Hong Kong due to the start of World War II. There were 43 reported tropical cyclones, including 27 that attained typhoon status. The first storm was observed in February, and the first typhoon formed two months later, killing three people along Mindanao. Several storms formed in June and July, including reports of a typhoon in the newspapers that killed 52 in South Korea, and another typhoon reported in newspapers that killed one person on Samar after dropping heavy rainfall. The strongest typhoon of the season originated in July and attained a minimum pressure of 927 mbar (27.4 inHg), as reported by a ship northeast of the Philippines.
In 1900, 23 tropical cyclones were observed in the western Pacific Ocean, north of the equator and west of the International Date Line. In that region of the world, cyclones that attain maximum sustained winds of at least 118 km/h (73 mph) are known as typhoons. Of the 23 storms, 13 were tracked by the Hong Kong Observatory. Activity occurred from January to December, although the majority of the storms formed from June to November.
In 1901, 21 tropical cyclones were observed in the western Pacific Ocean, north of the equator. In that region of the world, cyclones that attain maximum sustained winds of at least 118 km/h (73 mph) are known as typhoons. Out of the 21 storms, the Hong Kong Observatory tracked nine of them. The strongest storm, known as the De Witte typhoon, reached a minimum barometric pressure of 920 mbar (27 inHg), before striking eastern China.
In 1927, there were 27 tropical cyclones observed in the western Pacific Ocean, north of the equator and west of the 180th meridian. Many of these storms affected the Philippines, China, and Japan, collectively leaving 15,952 fatalities. The strongest storm of the year also had the lowest barometric pressure recorded in a tropical cyclone worldwide at the time. On August 18, the Dutch steamship Sapoeroea recorded a barometric pressure of 886.7 millibar about 740 kilometres (460 miles) east of Luzon. This typhoon later struck near Hong Kong, where it halted transportation, wrecked buildings, and killed 15 people.
The 1943 Pacific typhoon season has no official bounds; it ran year-round in 1943, 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 1943 Pacific hurricane season.
The 1944 Pacific typhoon season has no official bounds; it ran year-round in 1944, 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 1944 Pacific hurricane season.
There were 30 tropical cyclones in the western Pacific Ocean in 1931, including 19 typhoons, as well as one that developed in December of the previous year. The most significant typhoon was one that struck eastern China near Shanghai in the midst of the country's worst floods on record; heavy rainfall caused levees to collapse along the Grand Canal, killing an estimated 300,000 people, including about 2,000 people overnight in the city of Gaoyou.
The following is a list of Pacific typhoon seasons from 1920 to 1935. Data from these years was extremely unreliable, so there were many more typhoons that did not hit land and were not detected by ships. The average from these times was 23 tropical storms, which now would be considered a well-below-average season.
This article encompasses the 1890s Pacific typhoon seasons.
In 1935, there were 24 tropical cyclones across the western part of the Pacific Ocean.
