five seasons=1975, 1976, 1977, 1978, 1979The 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. This season was the most inactive in known history. Only eight tropical storms formed, and four hurricanes. Zero major hurricanes formed; the next time this happened would be the 2003 season. In addition, there was just one storm in each of May, June, July, August, and October, which is also low; the other three storms were in September. 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.

1977 Storm names

This is the same list used in the 1973 season. This is also the last time that this list was used, as modern naming began in 1978. This is therefore the final Pacific hurricane season to have lists with only female names.

The central Pacific used names and numbers from the western Pacific's typhoon list. No names were required.
