List of off-season Pacific hurricanes

[nb 1] The National Oceanic and Atmospheric Administration (NOAA) currently defines the season as starting May 15 in the eastern Pacific and June 1 for the central Pacific and ending on November 30 for both regions in each calendar year.

Few off-season tropical cyclones in the east Pacific have affected land, and none of them have made landfall.

In 1997, after Tropical Storm Paka crossed the International Date Line, it intensified into a typhoon with winds equivalent to a Category 5 hurricane on the Saffir–Simpson hurricane wind scale, and caused $580 million (1997 USD) in damage in the Marshall Islands, Guam, and the Northern Mariana Islands.

Since then, thirteen storms have occurred[2][6] outside the official bounds of hurricane season in the eastern and central north Pacific, respectively.

[7][8] There have been documents published in the Monthly Weather Review reporting additional off-season storms within 2,000 mi (3,220 km) of the Mexican coastline, including one in December.
