The season lasted a total 171 days beginning with the formation of Adrian and early June and the dissipation of Tropical Depression Twenty on November 25. There was a total of 924 storms hours and 631 hurricane hours. By comparison, the long-term averages at that time were 161 season days, 875 tropical storm hours, and 664 hurricane hours. 397 advisories were issued, which was below the 1977–1987 average of 428. The Hurricane Hunters did not fly into any of the storms in 1987. This was also the first year where tropical storm watches and warnings were issued instead of gale watches and warnings for tropical cyclones. 1987 was the last season that the Eastern Pacific Hurricane Center in Redwood City was responsible for forecasting in this basin, a task it had performed since circa 1972. The EPHC was folded into the National Hurricane Center, which took responsibility for the basin starting in the spring of 1988.
