Timeline of the 2013 Pacific hurricane season

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 season produced twenty-one tropical depressions. All but one further intensified into tropical storms and nine further intensified to become hurricanes. Despite this level of activity, only one hurricane – Raymond – strengthened into a major hurricane. The most significant storm, in terms of loss of life and damage, was Hurricane Manuel. Forming in mid-September, Manuel attained its peak as a minimal Category 1 hurricane before moving ashore on the coastline of Mexico. In total, the storm contributed to 123 confirmed fatalities and $4.2 billion (2013 USD) in damage. Throughout the duration of the season, four other named storms – Hurricane Barbara and tropical storms Juliette, Octave, and Sonia – made landfall in Mexico, causing minor damage and loss of life.

This timeline includes information that was not released in real time, but derived from post-season analyzes by the National Hurricane Center and Central Pacific Hurricane Center; as a result, it may include storms that were not operationally warned upon. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
