The 1987 Pacific hurricane season was the last year in which the Eastern Pacific Hurricane Center was the primary warning center for tropical cyclones in the eastern Pacific Ocean. The season officially started May 15, 1987 in the eastern Pacific, and June 1, 1987 in the central Pacific, and lasted until November 30, 1987. These dates conventionally delimit the period of each year when the vast majority tropical cyclones form in the northeastern Pacific Ocean.
