The 1968 Pacific hurricane season ties the record for having the most active August in terms of tropical storms. It officially started on May 15, 1968, in the eastern Pacific and June 1 in the central Pacific and lasted until November 30, 1968. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.
Several notable systems formed during the season. Five named storms—Hyacinth, Iva, Liza, Naomi, and Pauline—had effects in the United States. Two others—Annette and Tropical Depression Two—affected Mexico, and Tropical Storm Simone made a rare landfall on Guatemala. Tropical Storm Virginia, which formed in the West Pacific, crossed into the basin at a high latitude.
Timeline of tropical activity in the 1968 Pacific hurricane season
Twenty-five tropical cyclones formed this season, resulting in 501 advisories being issued in the East Pacific, and 30 being issued for the Central Pacific, both records at the time. Of these, six remained depressions, thirteen peaked as tropical storms, and six reached hurricane strength. There were no major hurricanes this season. Many of the tropical cyclones this season – including all six hurricanes – formed from Intertropical Convergence Zone (ITCZ) disturbances. Eight tropical storms formed in August this year, a record for the most active August in the East Pacific, excluding Virginia. The eight named storms forming in August this year also made it the most tropical storms to ever form in a month in the East Pacific since 1966. However, this record was tied during the 2009 Pacific hurricane season. Because of a lack of Hurricane Hunter data, a majority of the intensity readings from this season were later removed from the best track file. Only one pressure reading from this season – a 1,008 millibars (29.8 inHg) reading taken from Hurricane Pauline on October 29 when it was a tropical depression – was left on the best track data, although a pressure of 1,005 millibars (29.7 inHg) taken from Tropical Storm Simone was used to set its peak intensity.
