The 2005 Pacific hurricane season was a near-average season which produced fifteen named storms, only seven hurricanes formed and two major hurricanes. It was also the second consecutive season in which no tropical 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 2003 Pacific hurricane season was the first season to feature no major hurricanes – storms of Category 3 intensity or higher on the Saffir–Simpson hurricane wind scale (SSHWS) – since 1977. The dates conventionally delimiting the period when most tropical cyclones form in the Pacific Ocean are May 15 in the Eastern Pacific Ocean and June 1 in the Central Pacific, with both seasons ending on November 30. The 2003 season featured 16 tropical storms between May 19 and October 26; 7 of these became hurricanes, which was then considered an average season. Damage across the basin reached US$129 million, and 23 people were killed by the storms.
The 2001 Pacific hurricane season was a relatively near-average Pacific hurricane season which produced sixteen named storms, though most were rather weak and short-lived including one unnamed tropical storm which was operationally recognized as a tropical depression, the first such occurrence since 1996. Only eight hurricanes formed and two major hurricanes. 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 1998 Pacific hurricane season was a fairly average Pacific hurricane season. Despite this, it had nine hurricanes and six major hurricanes, which was well above average. 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 that region. The first tropical cyclone developed on June 11, about ten days later than the normal start of the season. The final storm of the year, Hurricane Madeline, dissipated on October 20. Storm activity in the Central Pacific Hurricane Center's warning zone was low, with just one tropical depression observed in the region. Two tropical cyclones from the eastern Pacific also entered the central Pacific; the former did so as a hurricane.
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 1992 Pacific hurricane season is the most active Pacific hurricane season on record, featuring 27 named storms, and the third-costliest Pacific hurricane season in history, behind the 2013 season. The season also produced the second-highest ACE value on record in the basin, only surpassed by the 2018 season. 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 most tropical cyclones form in the northeastern Pacific Ocean. However, these bounds were easily exceeded when Hurricane Ekeka formed on January 28 and again a couple months later with Tropical Storm Hali.
The 1991 Pacific hurricane season was a near-average Pacific hurricane season. The worst storm this year was Tropical Storm Ignacio, which killed 23 people in Mexico and injured 40 others. Elsewhere, Hurricane Fefa caused flooding in Hawaii. Hurricane Kevin was the strongest system of the season and became the then longest-lasting hurricane in the eastern north Pacific basin at the time, and Hurricane Nora was the strongest November storm to that point. The season officially started on May 15, 1991, in the eastern Pacific, and on June 1, 1991, in the central Pacific. It lasted until November 30, 1991, in both basins. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.
The 1989 Pacific hurricane season was a near normal season. It officially started on May 15, 1989, in the eastern Pacific, and on June 1, 1989, in the central Pacific, and lasted until November 30, 1989. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. A total of 18 storms and 9 hurricanes formed, which was near long-term averages. Four hurricanes reached major hurricane status on the Saffir–Simpson scale.
The 1988 Pacific hurricane season was the least active Pacific hurricane season since 1981. It officially began 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 northeastern Pacific Ocean. The first named storm, Tropical Storm Aletta, formed on June 16, and the last-named storm, Tropical Storm Miriam, was previously named Hurricane Joan in the Atlantic Ocean before crossing Central America and re-emerging in the eastern Pacific; Miriam continued westward and dissipated on November 2.
Hurricane Juliette was a long-lived Category 4 hurricane in the 2001 Pacific hurricane season. It caused 12 deaths and $400 million in damage when it hit Baja California in late September. Juliette developed from a tropical wave that had previously produced a tropical depression. The wave moved from the Atlantic to the Eastern Pacific, where it started to intensify. Soon, it became a tropical storm and was named Juliette. It then became a hurricane two days later, after struggling to do so. Rapidly intensifying due to favourable conditions, Juliette reached Category 4 status. However, an eyewall replacement cycle caused Juliette to significantly weaken down to a Category 2 hurricane. It eventually completed the cycle, and Juliette was able to reintensify to its peak intensity of 145 mph and 923 milibars. Another eyewall replacement cycle ensued however, resulting in Juliette having 3 eyewalls at once, which is an extremely rare occurrence. Eventually, Juliette weakened to a tropical storm, but Juliette's circulation was still well-defined. Warm waters allowed it to re-intensify to a hurricane, but this was short-lived as Juliette meandered near Baja California and its center became difficult to locate. It made landfall on Baja California as a tropical storm. Its circulation reached the Gulf of California, where it restrengthened slightly. Juliette made landfall on Baja California and dissipated on October 3.
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.
Tropical Storm Emilia was a rare tropical cyclone that affected the Baja California Peninsula in July 2006. The sixth tropical depression and fifth tropical storm of the 2006 Pacific hurricane season, it developed on July 21 about 400 miles (640 km) off the coast of Mexico. It moved northward toward the coast, reaching peak winds of 65 mph (105 km/h) before turning westward and encountering unfavorable conditions. Emilia later turned to the north, passing near Baja California as a strong tropical storm. Subsequently, the storm moved further away from the coast, and on July 27 it dissipated.
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. Only eleven hurricanes formed and six 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 at least one cyclone of 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 2009 Pacific hurricane season was the most active Pacific hurricane season since 1997. The 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 Eastern Pacific tropical cyclone basin; however, tropical cyclone formation is possible at any time of the year. The first system of the season, Tropical Depression One-E, developed on June 18, and the last, Hurricane Neki, dissipated on October 27, keeping activity well within the bounds of the season.
Hurricane Juliette was the strongest hurricane and final tropical cyclone of the inactive 1995 Pacific hurricane season. The tenth named storm of the season, Juliette formed on September 16 from a tropical wave off the southwest coast of Mexico. For the majority of its track, the storm moved toward the west-northwest, and Juliette quickly intensified to major hurricane status. On September 20, the hurricane reached peak winds of 150 mph (240 km/h). Later it turned toward the northeast, briefly threatening the Baja California Peninsula, although the hurricane never affected land.
The 2013 Pacific hurricane season was the first to see twenty named storms since 2009 but also had the ninth fewest ACE units on record, as many of the storms were weak and short-lived. The season officially began on May 15 in the Eastern Pacific and started on June 1 in the Central Pacific; both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form east of the International Dateline in the North Pacific basin. The first cyclone, Tropical Storm Alvin, formed on May 15, and the last, Tropical Storm Sonia, dissipated on November 4.
Hurricane Hilary was a Category 3 hurricane during the 1993 Pacific hurricane season that brought significant rainfall to the Sonoran Desert region of Mexico and the United States in August of that year. Additionally, its remnants in part caused significant flooding in the Midwestern United States. A westward moving tropical depression gradually developed on August 17 south of the Mexican coast, attaining hurricane status two days later. The storm further intensified into a Category 3 hurricane, attaining peak winds of 120 mph (195 km/h). By August 23, the hurricane nearly stalled while interacting with Tropical Storm Irwin. Executing a small counter-clockwise loop, Hilary degraded to tropical storm intensity and took a northerly track for the remainder of its existence. The storm made two landfalls in Mexico, one in Baja California Sur on August 25 and one in Sonora the following day. Tropical cyclone warnings and watches were issued for much of the southern Mexican coastline; however, they were later discontinued when the threat ended, but were issued again when the system posed a threat to the Baja California Peninsula. Hilary dropped in excess of 5 in (130 mm) rain along its path in some areas, and flash flooding in California and Iowa.
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 2019 Pacific hurricane season was a near average season which produced nineteen named storms, though most were rather weak and short-lived. Only seven hurricanes formed, the fewest since 2010. The season officially began 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. This season was one of the latest-starting Pacific hurricane seasons on record, with the first tropical cyclone, Hurricane Alvin, forming on June 25. The final system, Tropical Depression Twenty-One-E, dissipated on November 18.
