Hurricane Iwa, taken from the Hawaiian language name for the frigatebird, was at the time the costliest hurricane to affect the state of Hawaiʻi. Iwa was the twenty-third tropical storm and the twelfth and final hurricane of the 1982 Pacific hurricane season. It developed from an active trough of low pressure near the equator on November 19. The storm moved erratically northward until becoming a hurricane on November 23 when it began accelerating to the northeast in response to strong upper-level flow from the north. Iwa passed within 25 miles of the island of Kauaʻi with peak winds of 90 mph (140 km/h) on November 23, and the next day it became extratropical to the northeast of the state.
Hurricane John, also known as Typhoon John, was the farthest-traveling tropical cyclone ever observed worldwide. It was also the longest-lasting tropical cyclone on record globally at the time, until it was surpassed by Cyclone Freddy in 2023. John formed during the 1994 Pacific hurricane season, which had above-average activity due to the El Niño of 1994–1995, and peaked as a Category 5 hurricane on the Saffir–Simpson scale, the highest categorization for hurricanes.
The 2000 Pacific hurricane season was an above-average Pacific hurricane season, although most of the storms were weak and short-lived. There were few notable storms this year. Tropical storms Miriam, Norman, and Rosa all made landfall in Mexico with minimal impact. Hurricane Daniel briefly threatened the U.S. state of Hawaii while weakening. Hurricane Carlotta was the strongest storm of the year and the second-strongest June hurricane in recorded history. Carlotta killed 18 people when it sank a freighter. Overall, the season was significantly more active than the previous season, with 19 tropical storms. In addition, six hurricanes developed. Furthermore, there were total of two major hurricanes.
The 1999 Pacific hurricane season was one of the least active Pacific hurricane seasons on record. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; in both basins, it 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, Hurricane Adrian, developed on June 18, while the final storm of the season, Tropical Storm Irwin, dissipated on October 11. No storms developed in the Central Pacific during the season. However, two storms from the Eastern Pacific, Dora and Eugene, entered the basin, with the former entering as a hurricane and becoming the second farthest travelling Pacific hurricane on record.
The 1995 Pacific hurricane season was the least active Pacific hurricane season since 1979, and marked the beginning of a multi-decade period of low activity in the basin. Of the eleven tropical cyclones that formed during the season, four affected land, with the most notable storm of the season being Hurricane Ismael, which killed at least 116 people in Mexico. The strongest hurricane in the season was Hurricane Juliette, which reached peak winds of 150 mph (240 km/h), but did not significantly affect land. Hurricane Adolph was an early-season Category 4 hurricane. Hurricane Henriette brushed the Baja California Peninsula in early September.
The 1985 Pacific hurricane season is the third-most active Pacific hurricane season on record. It officially started on May 15, 1985, in the eastern Pacific, and on June 1, 1985, in the central Pacific, and lasted until November 30, 1985. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. At the time, the 1985 season was the most active on record in the eastern north Pacific, with 28 tropical cyclones forming. Of those, 24 were named, 13 reached hurricane intensity, and 8 became major hurricanes by attaining Category 3 status or higher on the Saffir–Simpson scale. At that time, the 24 named storms was a record; however, this record was broken seven years later in 1992, and was therefore recognized as the second busiest season within the basin, until it was surpassed exactly thirty years later by the 2015 season.
The 1982 Pacific hurricane season was, at the time, the most active Pacific hurricane season on record, with 23 named storms. Of those, 12 became hurricanes, with 5 intensifying into major hurricanes. The season officially started on May 15 in the eastern Pacific basin and June 1 in the central Pacific basin. The season in both basins ended on November 30. These dates conventionally delimit the period during which most tropical cyclones form in these regions of the Pacific Ocean. The first tropical cyclone of the season, Tropical Storm Aletta, formed on May 20, and the final one of the season, Hurricane Iwa, dissipated on November 25. A strengthening El Niño that year fueled the season's above normal activity.
Hurricane Fefa was the only tropical cyclone during the 1991 Pacific hurricane season to directly impact the Hawaiian Islands. The sixth tropical storm, fourth hurricane, and second major hurricane of the season, the storm developed from a tropical wave on July 29 about 975 miles (1,569 km) south-southeast of Cabo San Lucas. It moved west-northwestward, and under generally favorable conditions it strengthened to attain peak winds of 120 mph (190 km/h) on August 2. Fefa turned to the west towards Hawaii, and slowly weakened until dissipating near the island of Hawaii.
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 1978 Pacific hurricane season was the first Pacific hurricane season to use both masculine and feminine names for tropical cyclones. It also began the modern practice of utilizing naming lists every six years. Despite lacking an El Niño, a common driver of enhanced activity in the East and Central Pacific basins, the 1978 season was active. It featured 19 named storms, 14 hurricanes, and 7 major hurricanes, the latter of which are Category 3 or stronger cyclones on the Saffir–Simpson scale. Within the confines of the Central Pacific basin, located between the International Date Line and 140°W, 13 tropical cyclones or their remnants were observed by forecasters at the Central Pacific Hurricane Center, a record number of occurrences at the time. Seasonal activity began on May 30 and ended on October 21, within the limits of a traditional hurricane season which begins on May 15 in the East Pacific and June 1 in the Central Pacific. The season ends on November 30 in both basins. These dates conventionally delimit the period during each year when most tropical cyclones form.
The 2007 Pacific hurricane season was a well below-average Pacific hurricane season, featuring only one major hurricane. The season officially started on May 15 in the eastern Pacific and on June 1 in the central Pacific, and ended on November 30; these dates conventionally delimit the period during which most tropical cyclones form in the region. The first tropical cyclone of the season, Alvin, developed on May 27, while the final system of the year, Kiko, dissipated on October 23. Due to unusually strong wind shear, activity fell short of the long-term average, with a total of 11 named storms, 4 hurricanes, and 1 major hurricane. At the time, 2007 featured the second-lowest value of the Accumulated cyclone energy (ACE) index since reliable records began in 1971. Two tropical cyclones – Cosme and Flossie – crossed into the central Pacific basin during the year, activity below the average of 4 to 5 systems.
Hurricane Dora was one of few tropical cyclones to track across all three north Pacific basins and the first since Hurricane John in 1994. The fourth named storm, third hurricane, and second major hurricane of the 1999 Pacific hurricane season, Dora developed on August 6 from a tropical wave to the south of Mexico. Forming as a tropical depression, the system gradually strengthened and was upgraded to Tropical Storm Dora later that day. Thereafter Dora began heading in a steadily westward direction, before becoming a hurricane on August 8. Amid warm sea surface temperatures and low wind shear, the storm continued to intensify, eventually peaking as a 140 mph (220 km/h) Category 4 hurricane on August 12.
Hurricane Daniel was the second strongest hurricane of the 2006 Pacific hurricane season. The storm affected Hawaii late in its lifetime, causing moderate rainfall and minor damage. The fourth named storm, third hurricane, and second major hurricane of the season, Daniel originated on July 16 from a tropical wave off the coast of Mexico. It tracked westward, intensifying steadily to reach peak winds of 150 mph (240 km/h) on July 22. At the time, the characteristics of the cyclone resembled those of an annular hurricane. Daniel gradually weakened as it entered an area of cooler water temperatures and increased wind shear, and after crossing into the Central Pacific Ocean, it quickly degenerated into a remnant low on July 26, before dissipating two days later.
Hurricane Emilia was, at the time, the strongest tropical cyclone on record in the Central Pacific Ocean, and the second of such to be classified as a Category 5 hurricane – the highest rating on the Saffir–Simpson hurricane wind scale. However, hurricanes Gilma later that year, Ioke in 2006, and Walaka in 2018 later reached lower barometric pressures in the Central Pacific. In addition, Emilia was the first Category 5 Pacific hurricane since Hurricane Ava in 1973. The fifth named storm and the first of three Category 5 hurricanes of the 1994 hurricane season, Emilia developed from an area of low pressure southeast of Hawaii on July 16. Tracking westward, the initial tropical depression intensified into a tropical storm several hours after tropical cyclogenesis. Subsequently, Emilia entered the Central Pacific Ocean and moved into the area of responsibility of the Central Pacific Hurricane Center (CPHC).
The 2006 Pacific hurricane season was the first above-average season since 1997 which produced twenty-five tropical cyclones, with nineteen named storms, though most were rather weak and short-lived. There were eleven hurricanes, of which six became major hurricanes. Following the inactivity of the previous seasons, forecasters predicted that season would be only slightly above active. It was also the first time since 2003 in which one cyclone of at least tropical storm intensity made landfall. The season officially began on May 15 in the East Pacific Ocean, and on June 1 in the Central Pacific; they ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year.
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.
Hurricane Fernanda was the first significant hurricane threat to Hawaii since Hurricane Iniki struck in September 1992. The sixth named storm and third major hurricane of the 1993 Pacific hurricane season, Fernanda developed on August 9 off the coast of Mexico from a tropical wave. Throughout its life, it was a large system, and the hurricane reached peak winds of 145 mph (233 km/h). After weakening slightly, Fernanda restrengthened and was expected to move across the Hawaiian Islands. Instead, the hurricane slowed its forward motion and turned away from the state, although it still produced high waves along the eastern shore of the islands. Several homes were damaged, and the surf damaged coastal roads. The storm also contributed to rainfall across the state, and minor flooding occurred in Kauai. Fernanda became extratropical on August 19, and after turning to the northeast became absorbed by a cold front.
Hurricane Estelle was a powerful tropical cyclone that caused minor damage and two deaths in Hawaii in July 1986. Estelle was the sixth tropical cyclone, fifth named storm, third hurricane, and first major hurricane of the above-average 1986 Pacific hurricane season. It formed as a tropical depression formed well southwest of the Baja California Peninsula on July 16, and strengthened into a tropical storm within 24 hours. Located within a favorable environment, Estelle intensified into a hurricane on July 18. It attained major hurricane status two days later. After peaking in intensity at Category 4 strength, Estelle slowly weakened. By July 24, Estelle was no longer a hurricane while passing south of Hawaii. It completely dissipated on July 26 after further deteriorating to a tropical depression. The arrival of the hurricane prompted a hurricane watch for Hawaii, and 200 people evacuated from their homes. Hurricane Estelle produced high waves offshore Hawaii, causing $2 million in damage and two deaths. The remnants of the storm also produced intermittent showers across the state, though there was no major damage.
Hurricane Ignacio was a Pacific hurricane that threatened Hawaii during July 1985, but ultimately had little impact on the island chain. Ignacio was the eleventh tropical cyclone, ninth named storm, and third hurricane and major hurricane of the very active 1985 Pacific hurricane season. A tropical depression formed on July 21 far from land. It became Tropical Storm Ignacio later that day. Ignacio then rapidly intensified and peaked with 130 mph (215 km/h) winds on July 24. Ignacio weakened quickly, though it briefly leveled off in intensity as a Category 2 hurricane. Ignacio was downgraded into a tropical storm on July 26 while passing south of Hawaii. Continuing to weaken, Ignacio dissipated on July 27. A hurricane watch was briefly issued for the Hawaiian Islands even though the watch was dropped when Ignacio weakened. However, Ignacio still brought high waves and light rainfall to the islands. A few roads were closed, but otherwise, damage was minimal.
