List of Pacific Hurricanes - Duration Records

Duration Records

This lists all Pacific hurricanes that existed as tropical cyclones while in the Pacific Ocean east of the dateline for more than two weeks continuously. Hurricanes John and Dora spent some time in the west Pacific before dissipating. John spent eleven days west of the dateline; if that time was included John would have existed for a total of 30 days and 18 hours, a world record, while including Dora's time in the west Pacific would mean that it existed for 18 days. One Atlantic hurricane, Hurricane Joan, crossed into this basin and was renamed Miriam, giving it a total lifespan of 22 days, but not all of that was in the Pacific. 1993's Greg formed from the remnants of 1993's Tropical Storm Bret. Its time as an Atlantic system is excluded.

All of these systems except Trudy, Olaf, and Connie existed in both the east and central Pacific, and all except Olaf were hurricanes. Hurricane Trudy of 1990 is thus the longest lived eastern Pacific hurricane to stay in the eastern Pacific. Tropical Storm Olaf of 1997 is hence the longest-lived eastern Pacific tropical cyclone not to reach hurricane intensity.

No known tropical cyclone forming in the central north Pacific lasted for longer than 14 days without crossing into another basin. The tropical cyclone forming in the central Pacific that spent the most time there was 1988's Hurricane Uleki at 11.5 days from formation to crossing the dateline.

Before the weather satellite era began, the lifespans of many Pacific hurricanes may be underestimated.
