The 2012 Pacific hurricane season was a moderately active Pacific hurricane season that saw an unusually high number of tropical cyclones pass west of the Baja California Peninsula. The season officially began on May 15 in the eastern Pacific Ocean, and on June 1 in the central Pacific (from 140°W to the International Date Line, north of the equator; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in these regions of the Pacific Ocean. However, the formation of tropical cyclones is possible at any time of the year. This season's first system, Tropical Storm Aletta, formed on May 14, and the last, Tropical Storm Rosa, dissipated on November 3.
The 2009 Pacific hurricane season officially started on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. No tropical cyclones formed during the month of May, making 2009 the first time that no tropical cyclones formed during May since 1999. The first tropical cyclone of the year, Tropical Depression One-E, formed June 18, and dissipated the following day. The first named storm of the season, Hurricane Andres formed on June 21. The final storm of the season, Neki, dissipaed on October 27.
The 2000 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. There was above-normal activity during the season, with nearly all its activity occurring during a three-month period, August–October. The season officially began on June 1, 2000 and ended on November 30, 2000. These dates, adopted by convention, historically describe the period in each year when most tropical systems form. Although two tropical depressions formed in June, the first named storm, Alberto, did not arise until August 4. The season's final storm, an unnamed subtropical storm, became extratropical on October 29.
The 2010 Pacific hurricane season was one of the least active seasons on record, featuring the fewest named storms since 1977. The season officially started on May 15 in the eastern Pacific—east of 140°W—and on June 1 in the central Pacific—between the International Date Line and 140°W—and lasted until November 30. These dates typically cover the period of each year when most tropical cyclones form in the eastern Pacific basin. The season's first storm, Tropical Storm Agatha, developed on May 29; the season's final storm, Tropical Storm Omeka, degenerated on December 21.
The 2013 Pacific hurricane season was an above-average year in which twenty named storms developed. The hurricane season officially began on May 15 in the East Pacific, coinciding with the formation of Tropical Storm Alvin, and on June 1 in the Central Pacific; it ended on November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form. The final system of the year, Tropical Storm Sonia, dissipated on November 4.
The 2014 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation. It officially began on May 15 in the eastern Pacific—defined as the region east of 140°W—and began on June 1 in the central Pacific, defined as the region west of 140°W to the International Date Line; both ended on November 30.
The 2015 Atlantic hurricane season was an event in the annual hurricane season in the north Atlantic Ocean. It was the third consecutive year to feature below-average tropical cyclone activity, with eleven named storms. The season officially began on June 1, 2015 and ended on November 30, 2015. These dates, adopted by convention, historically describe the period in each year when most tropical systems form. However, systems can and do form outside these dates, as did the season's first storm, Tropical Storm Ana, which developed on May 8; the season's final storm, Hurricane Kate, lost its tropical characteristics on November 11.
The 2015 Pacific hurricane season was the second-most active Pacific hurricane season on record, and featured the strongest tropical cyclone ever observed in the Western Hemisphere: Hurricane Patricia. The season officially started on May 15 in the Eastern Pacific—east of 140°W—and on June 1 in the Central Pacific—between the International Date Line and 140°W—and ended on November 30. These dates typically cover the period of each year when most tropical cyclones form in the Northeastern Pacific tropical cyclone basin. The season's first storm, Hurricane Andres, developed on May 28; the season's final storm, Tropical Depression Nine-C, dissipated on December 31, well after the official end of the season.
The 2016 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the eastern Pacific Ocean. The season officially started on May 15 in the eastern Pacific–east of 140°W–and on June 1 in the central Pacific–between the International Date Line and 140°W–and ended on November 30. These dates typically cover the period of each year when most tropical cyclones form in the eastern Pacific basin. However the first storm, Pali, formed 5 months before the official start of the season on January 7, which broke the record for having the earliest forming storm within the basin.
The 2017 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. This Atlantic hurricane season saw above-normal activity; it was the seventh most active season on record and the most active since 2005. The season officially began on June 1, 2017 and ended on November 30, 2017. These dates, adopted by convention, historically describe the period in each year when most tropical systems form. However, storm formation is possible at any time of the year, as demonstrated in 2017 by the formation of the season's first named storm, Tropical Storm Arlene, on April 19. The final storm of the season, Tropical Storm Rina degenerated to a remnant area of low pressure on November 9.
The 2017 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the eastern Pacific Ocean. The season officially started on May 15 in the eastern Pacific—east of 140°W—and on June 1 in the central Pacific—between the International Date Line and 140°W—and ended on November 30. These dates typically cover the period of each year when most tropical cyclones form in the eastern Pacific basin. However, storm formation is possible at any time of the year, as illustrated in 2017 by the formation of the season's first named storm, Tropical Storm Adrian, on May 10. At the time, this was the earliest formation of a tropical storm on record in the basin.
The 2021 Pacific hurricane season was a moderately active Pacific hurricane season, with above-average activity in terms of number of named storms, but below-average activity in terms of major hurricanes, as 19 named storms, 8 hurricanes, and 2 major hurricanes formed in all. It also had a near-normal accumulated cyclone energy (ACE). The season officially began on May 15, 2021 in the Eastern Pacific Ocean, and on June 1, 2021, in the Central Pacific in the Northern Hemisphere. The season ended in both regions on November 30, 2021. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention. However, the formation of tropical cyclones is possible at any time of the year, as illustrated by the formation of Tropical Storm Andres on May 9, which was the earliest forming tropical storm on record in the Eastern Pacific. Conversely, 2021 was the second consecutive season in which no tropical cyclones formed in the Central Pacific.
The 2019 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was the fourth consecutive above-normal Atlantic hurricane season. The season officially began on June 1, 2019 and ended on November 30, 2019. These dates, adopted by convention, historically describe the period in each year when most tropical systems form. However, storm formation is possible at any time of the year, as demonstrated in 2019 by the formation of the season's first named storm, Subtropical Storm Andrea, on May 20. The final storm of the season, Tropical Storm Sebastien, transitioned to an extratropical cyclone on November 25.
The 2019 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the eastern Pacific Ocean. The season officially started on May 15 in the eastern Pacific—east of 140°W—and June 1 in the central Pacific—between the International Date Line and 140°W, and ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the eastern Pacific basin.
The 2020 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the Eastern Pacific Ocean. The season officially started on May 15 in the Eastern Pacific—east of 140°W—and began on June 1 in the Central Pacific—the region between the International Date Line and 140°W–and ended on November 30. These dates typically cover the period of each year when most tropical cyclones form in the Eastern Pacific basin according to the National Hurricane Center. However, tropical cyclones sometimes form outside the bounds of an official season, as was evidenced by the formation of Tropical Depression One-E on April 25. The season effectively ended with the dissipation of its final storm, Tropical Storm Polo, on November 19.
Hurricane Douglas was a strong tropical cyclone that became the closest passing Pacific hurricane to the island of Oahu on record, surpassing the previous record held by Hurricane Dot in 1959. The eighth tropical cyclone, fifth named storm, first hurricane, and first major hurricane of the slightly below-average 2020 Pacific hurricane season, Douglas originated from a tropical wave which entered the basin in mid-July. Located in favorable conditions, the wave began to organize on July 19. It became a tropical depression on July 20 and a tropical storm the following day. After leveling off as a strong tropical storm due to dry air, Douglas began rapid intensification on July 23, becoming the season's first major hurricane the following day and peaking as a Category 4 hurricane. After moving into the Central Pacific basin, Douglas slowly weakened as it approached Hawaii. The storm later passed north of the main islands as a Category 1 hurricane, passing dangerously close to Oahu and Kauai, causing minimal damage, and resulting in no deaths or injuries. Douglas weakened to tropical storm status on July 28, as it moved away from Hawaii, before degenerating into a remnant low on July 29 and dissipating on the next day.
Hurricane Genevieve was a strong tropical cyclone that almost made landfall on the Baja California Peninsula in August 2020. Genevieve was the twelfth tropical cyclone, eighth named storm, third hurricane, and second major hurricane of the 2020 Pacific hurricane season. The cyclone formed from a tropical wave that the National Hurricane Center (NHC) first started monitoring on August 10. The wave merged with a trough of low pressure on August 13, and favorable conditions allowed the wave to intensify into Tropical Depression Twelve-E at 15:00 UTC. Just six hours later, the depression became a tropical storm and was given the name Genevieve. Genevieve quickly became a hurricane by August 17, and Genevieve began explosive intensification the next day. By 12:00 UTC on August 18, Genevieve reached its peak intensity as a Category 4 hurricane, with maximum 1-minute sustained winds of 130 mph and a minimum central pressure of 950 millibars (28 inHg). Genevieve began to weaken on the next day, possibly due to cooler waters caused by Hurricane Elida earlier that month. Genevieve weakened below tropical storm status around 18:00 UTC on August 20, as it passed close to Baja California Sur. Soon afterward, Genevieve began to lose its deep convection and became a post-tropical cyclone by 21:00 UTC on August 21, eventually dissipating off the coast of Southern California late on August 24.
The 2022 Pacific hurricane season was a fairly active tropical cyclone season, with 19 named storm altogether. Ten of those became hurricanes, and four further intensified into major hurricanes. Two of this season's storms, Bonnie and Julia, survived the overland crossover from the Atlantic. The season officially started on May 15 in the eastern Pacific—east of 140°W—and June 1 in the central Pacific—between the International Date Line and 140°W, and ended in both regions on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the eastern Pacific basin. The season's first storm, Agatha, formed on May 28, and last, Roslyn, dissipated on October 23. Rosyln made landfall in Nayarit with 120 mph (195 km/h) winds, making it the strongest landfalling Pacific hurricane since Patricia in 2015. The season's first major hurricane, Bonnie, entered into the basin from the Atlantic basin on July 2, after crossing Nicaragua as a tropical storm, becoming the first storm to survive the crossover from the Atlantic to the Pacific since Otto in 2016. Three months later, Julia became the second to do so.
The 2023 Atlantic hurricane season is the current hurricane season, the annual period of tropical cyclogenesis in the Atlantic Ocean in the Northern Hemisphere. The season officially began on June 1, 2023, and will end on November 30, 2023. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclones form in the Atlantic. However, tropical cyclone formation is possible at any time of the year, as was the case this season, when an unnamed subtropical storm formed on January 16.
The 2023 Pacific hurricane season is the current tropical cyclone season in the Pacific Ocean east of the International Date Line (IDL) in the Northern Hemisphere. It officially began on May 15 in the eastern Pacific, and on June 1 in the central Pacific ; it will end in both on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclogenesis occurs in these regions of the Pacific. The season's first system, Tropical Storm Adrian, developed on June 27.
