The 2007 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, and dissipation. The timeline also includes information which was not operationally released, which is information from post-storm analysis by the National Hurricane Center.

The season officially started on May 15, 2007 in the eastern Pacific, designated as the area east of 140°W, and on June 1, 2007 in the central Pacific, which is between the International Date Line and 140°W, and lasted until November 30, 2007. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. The season began slowly; through the end of July, the seasonal Accumulated Cyclone Energy (ACE) was the third lowest since the geostationary satellite era began in the 1966 Pacific hurricane season.^[1] The inactivity continued through the next month, which was the third quietest August in terms of ACE since reliable records began in the basin during the 1971 Pacific hurricane season.^[2] In June, Tropical Storm Barbara caused $55 million (2007 USD) in crop damage to southeastern Mexico from heavy precipitation.^[3] In August, Hurricane Flossie formed in the eastern Pacific and crossed into the central Pacific; the hurricane threatened Hawaii but caused little damage. In early September, Hurricane Henriette dropped heavy rainfall in southwest Mexico, which caused nine fatalities and $25 million (2007 USD) in damage.^[4]
