The 1977 Pacific hurricane season officially started May 15, 1977 in the eastern Pacific, and June 1, 1977 in the central Pacific, and lasted until November 30, 1977. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The season was very inactive.

This season had a record low level of activity. Only eight tropical storms formed, and four hurricanes. Zero major hurricanes formed. The next time this happened was during the 2003 season. In addition, there was just one cyclogenesis in each of May, June, July, August, and October, which is also low. Activity in the central Pacific was zero, as no storms formed there nor moved in from the east.

The low seasonal activity also occurred in the Atlantic hurricane season and in the typhoon season of the western Pacific. This was a worldwide trend; various factors inhibited tropical cyclone development throughout the northern hemisphere, resulting in a record low level of tropical cyclones worldwide.

It paralleled Mexico, moving north. It brushed the extreme west of Mexico and dissipated before reaching California on the August 18. The remnants of the hurricane did bring heavy rain to California, however. The highest amount reported was 7.45 inches at Mount San Jacinto in southern California.[1] In desert areas in the southwestern part of the state, rains destroyed 325 homes and businesses and caused the evacuation of several people. Parts of the recently-repaired Interstate 8 were destroyed again, and two of the lanes of Interstate 25 were washed out. In San Diego and Imperial County, the total damage to agricultural interests was $25 million (1977 USD).
