The 1910s Pacific hurricane seasons all began on May 15 of their respective years in the eastern north Pacific Ocean and on June 1 in the central north Pacific. They ended on November 30 of each year. These dates conventionally delimit the time of year when most tropical cyclones form in northeast Pacific Ocean tropical cyclone basin, between the International Date Line and the west coast of North America. However, tropical cyclone formation is possible at any time of the year. Before the dawn of the satellite era in the 1960s, data on Pacific hurricanes is extremely unreliable. For a few years, there are no reported cyclones, although many systems likely formed and went undocumented.

Three known tropical cyclones formed in 1910. The remnants of one of them entered southern California on September 15, bringing 2 inches (51 mm) of rain to Santa Barbara County.
Eleven known tropical cyclones formed in 1911 in the eastern Pacific proper.
On September 11, Hurricane 4 of this year's Atlantic season survived passage over Central America and emerged into the Pacific Ocean, where it dissipated on September 12.
On September 29, a ship reported strong winds and a pressure of 998 mbar inside a storm to the east of Hawaii. There were no other reports of this possible tropical cyclone.
A "tropical hurricane" formed southwest of Mexico on October 1. The system recurved, coming ashore on October 4 near Guaymas, accompanied by a devastating storm surge early on the morning of October 5, with some 500 reported dead. [1] It then crossed through western Mexico, before becoming an extratropical cyclone across the American southwest on October 5. The cyclone had a long life thereafter, moving east-northeast across the United States into the western Atlantic on October 7. Racing northeast, the cyclone moved over the Polar ice cap on October 11, arcing north of Europe, before dropping into northern Asia on October 13, then crossing through Siberia until October 21, when the low dissipated. [2]
A "tropical hurricane" formed south of Mexico on October 6. The system moved north-northwest, making landfall west of Acapulco on October 8, before dissipating inland on October 10. [2]
Four known tropical cyclones formed in 1912.
One of them, which stayed at sea, was tracked from August 10 to 11 of this year.
A "tropical hurricane" formed southwest of Mexico on October 23. The cyclone moved northwest, then northward, through western Mexico on October 26 before dissipating on October 27. [2]
There was only one known tropical cyclone in 1913.
There were no known tropical cyclones.
Four tropical cyclones formed in 1915.
On July 4, a system formed WNW of Cocos Island. It made landfall near Salina Cruz two days later.
A tropical cyclone hit northern Baja California in late August. Its remnants entered California on August 26, bringing light rains amounting to 1-inch (25 mm).
A "tropical hurricane" moved just offshore the coasts of southern and western Mexico between September 3 and 7. [3]
There were no known tropical cyclones.
Four tropical cyclones formed in 1917.
A "tropical hurricane" formed southwest of Mexico on August 29, moved northward into western Mexico on September 1. [3]
Three tropical cyclones formed in the eastern Pacific in 1918.
On September 13, a hurricane was discovered off the coast of Acapulco. It paralleled the coast and moved slightly inland. After reentering the Pacific Ocean, it made landfall in the Gulf of California side of the Baja California Peninsula. This hurricane's remnants continued north into California. This system was destructive. Several people in San José del Cabo were killed, and several houses and buildings were destroyed. In La Paz, every ship was either sunk, run aground, or damaged. Several vessels at sea were also sunk. This system's remnants produced light rains in Southern California. When they reached Northern California on September 17, they caused heavy precipitation amounting to 7 inches (180 mm). A total of twenty-five deaths were reported, mainly from drowning or falling trees. Damage was at least 200,000 pesos. [4] [5]
On September 29, a "tropical hurricane" moved by Johnston Island to the north-northeast, converting into an extratropical cyclone by October 1. The system raced east-northeast, moving through the Alaskan panhandle into western Canada on October 5. The cyclone then moved westward across Canada until October 10, when it dissipated. [3]
There were two known tropical cyclones.
The 1973 Atlantic hurricane season was a below average tropical cyclone season overall. Of the 24 tropical or subtropical cyclones which developed, only 8 became named storms, and of those, only 4 became hurricanes, with 1 reaching major hurricane status on the newly implemented Saffir–Simpson hurricane wind scale. This continued the pattern of storm activity from the previous season, as hostile El Niño–Southern Oscillation (ENSO) conditions again hindered tropical cyclogenesis and intensification in the tropical Atlantic Ocean and Caribbean Sea.
The 1975 Atlantic hurricane season was a near average hurricane season with nine named storms forming, of which six became hurricanes. Three of those six became major hurricanes, which are Category 3 or higher systems on the Saffir–Simpson scale. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic Ocean.
The 1977 Atlantic hurricane season was a very inactive Atlantic hurricane season, with only six named storms. The season officially began on Wednesday, June 1, 1977 and lasted until Wednesday, November 30, 1977. These dates conventionally delimit the period of each year when most tropical cyclogenesis occurs in the Atlantic basin. The first tropical cyclone of the season developed over the western Caribbean Sea on June 13, 12 days after the start of the season. Three more organized during July and early August. Then, on August 29, the first named storm, Hurricane Anita formed and rapidly intensified to a Category 5 hurricane on September 1, before weakening slightly and striking Mexico as a high-end Category 4 hurricane on the Saffir–Simpson hurricane wind scale, bringing strong winds and heavy rainfall, causing 11 fatalities, and leaving at least 25,000 people homeless. Damage from Anita exceeded $956 million USD.
The 1949 Atlantic hurricane season was the last season that tropical cyclones were not publicly labeled by the United States Weather Bureau. It officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first storm, a tropical depression, developed in the northern Gulf of Mexico on August 14. The final system, Tropical Storm Sixteen, dissipated in the southwestern Caribbean Sea on November 5. It was a fairly active season, featuring 16 tropical storms and seven hurricanes. Two of these strengthened into major hurricanes, which are Category 3 or higher on the Saffir–Simpson hurricane wind scale.
The 1936 Atlantic hurricane season was a fairly active season, with 20 tropical cyclones recorded, 17 of which became tropical storms. Seven storms became hurricanes, of which one became a major hurricane. In addition, the season was unusual in the fact that no storms moved across large portions of the Caribbean Sea. Seven storms, including three hurricanes, struck the United States.
The 1921 Atlantic hurricane season was an active hurricane season, with 12 tropical cyclones forming. Among them, seven became tropical storms, of which five strengthened into hurricanes. Furthermore, two of these strengthened into a major hurricane, Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale, the most since the 1917 season. The first system, a tropical depression, developed on June 1, while the last, a tropical storm, dissipated on November 25. Of note, three tropical cyclones co-existed with another during the season.
The 1997 Pacific hurricane season was a very active hurricane season. With hundreds of deaths and hundreds of millions of dollars in damage, this was one of the deadliest and costliest Pacific hurricane seasons on record. This was due to the exceptionally strong 1997–98 El Niño event. The season officially started on May 15, in the eastern Pacific, and on June 1, in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when almost all tropical cyclones form in the northeastern Pacific Ocean.
The 1981 Pacific hurricane season was a slightly below average Pacific hurricane season. The season officially started on May 15 in the eastern Pacific basin and June 1 in the central Pacific basin. Both basins' seasons ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone of the season was designated on May 30, and the final storm of the season, Hurricane Otis, dissipated on October 30. The season produced fifteen named storms and a total of eight hurricanes, which was near normal. However, the total of one major hurricane was below the average of three.
The 1974 Pacific hurricane season featured one of the most active periods of tropical cyclones on record with five storms existing simultaneously. The season officially started May 15 in the eastern Pacific, and June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean.
The 1975 Pacific hurricane season officially started May 15, 1975, in the eastern Pacific, and June 1, 1975, in the central Pacific, and lasted until November 30, 1975. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean.
The 1920-24 Pacific hurricane seasons all began on May 15 of their respective years in the eastern north Pacific Ocean and on June 1 in the central north Pacific. They ended on November 30, of each year. These dates conventionally delimit the time of year when most tropical cyclones form in northeast Pacific Ocean tropical cyclone basin, between the International Date Line and the west coast of North America. However, tropical cyclone formation is possible at any time of the year. Before the dawn of the satellite era in the 1960s, data on Pacific hurricanes is extremely unreliable. For a few years, there are no reported cyclones, although many systems likely formed and went undocumented.
The 1970 Pacific typhoon season has no official bounds; it ran year-round in 1970, 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 1957 Pacific typhoon season has no official bounds; it ran year-round in 1957, 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 1900s Pacific hurricane seasons all began on May 15 of their respective years in the Eastern North Pacific Ocean and on June 1 in the Central North Pacific. They all ended on November 30, of each year. These dates conventionally delimit the period when tropical cyclogenesis usually occurs in the Northern Pacific basin, east of the International Date Line. However, Tropical cyclogenesis is possible at any time of the year. Before the dawn of the satellite era in the 1960s, data on Pacific hurricanes is extremely unreliable. For a few years, there are no reported cyclones, although many systems likely formed and went undocumented.
The 1960 Pacific hurricane season was an event in the annual seasons of Tropical Cyclone development. It officially started on May 15, 1960, in the eastern Pacific and lasted until November 30, 1960. The 1960 season was the first season that Eastern Pacific hurricanes were named.
The 1957 Pacific hurricane season was a moderately active year in which 13 tropical cyclones formed. The hurricane season ran through the summer and fall months which conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone developed on July 15. The final storm dissipated on December 6, becoming one of the few Pacific storms to exist outside of the seasonal dates. Of the season's 13 storms, five of these formed or crossed into the central Pacific.
During 2022, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones were named by various weather agencies when they attained maximum sustained winds of 35 knots. During the year, 133 systems formed, of which 87 were named. The strongest storm to form was Typhoon Nanmadol, with minimum pressure of 910 hPa (26.87 inHg). The deadliest tropical cyclone was Tropical Storm Megi, which caused 214 fatalities in the Philippines, while the costliest was Hurricane Ian, which had an estimated damage total of at least $113.1 billion after affecting Trinidad and Tobago, Venezuela, Colombia, the western part of the Greater Antilles and Southeast United States.
During 2023, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. They were named by various weather agencies when they attained maximum sustained winds of 35 knots. Throughout the year, a total of 115 systems formed, with 79 of them being named. The most intense storm this year was Typhoon Mawar, which had a minimum pressure of 900 hPa (26.58 inHg). The deadliest tropical cyclone of the year was Storm Daniel, which killed at least 10,028 people in Libya, Greece, Turkey, and Bulgaria. Meanwhile, the costliest tropical cyclone was Typhoon Doksuri which caused at least US$28.4 billion worth of damage in China, the Philippines and Taiwan, becoming the costliest on record outside the Atlantic Ocean basin. Among this year's systems, thirty became major tropical cyclones, of which nine intensified into Category 5 tropical cyclones on the Saffir–Simpson scale (SSHWS). This year, for the first time on record, at least one such Category 5 system formed in each tropical cyclone basin: Typhoons Mawar and Bolaven in the western Pacific Ocean, Hurricanes Jova and Otis in the eastern Pacific, Hurricane Lee in the Atlantic, Cyclone Mocha in the North Indian Ocean, Cyclone Freddy in the southwest Indian Ocean, Cyclone Ilsa in the Australian region, and Cyclone Kevin in the South Pacific. The accumulated cyclone energy (ACE) index for the 2023, as calculated by Colorado State University (CSU) was 857.4 units, which was above the 1991-2020 mean of 770.2 units.
