2013 WMHB Pacific hurricane season (Cooper)

The 2013 Pacific hurricane season was an active Pacific hurricane season, although most of the storms were weak and short-lived. The season officially started on May 15, 2018 in the eastern Pacific, and on June 1, 2018 in the central Pacific, while the season ended in both basins on November 30, 2018. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin.

Storm names
The following list of names was used for named storms that formed in the Northeastern Pacific in 2013. The names not retired from this list will be used again in the 2019 season. This was the same list used in the 2007 season, with the exceptions of Babs and Judy, which replaced Barbara and Janet, respectively.

For storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the area between 140 degrees west and the International Date Line, all names are used in a series of four rotating lists. The next four names slated for use are listed below.

Retirement
On April 10, 2014, at the 36th session of the RA IV hurricane committee, the World Meteorological Organizations retired the names Manuel and Sonia from its rotating name lists due to the amount of damage and deaths they caused, and they will not be used again for another Pacific hurricane. They were replaced with Mario and Sheila for the 2019 season.
