The 1987 North Indian Ocean cyclone season was part of the annual cycle of tropical cyclone formation. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. There are two main seas in the North Indian Ocean—the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November.[1] Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.[2]

Prior to 1992, this season had the most tropical storms in North Indian recorded history, with 8 storms forming.
Tropical Storm One, which developed in the central Bay of Bengal on January 30, turned to the north and reached a peak of 65 mph winds on the 2nd. Vertical shear weakened it to a tropical depression before it hit northern Myanmar on the 4th.
On June 4 65 mph Tropical Storm Two hit Bangladesh, causing little damage or loss of life.

A monsoon depression became more tropical on October 14 in the Bay of Bengal. It traveled northwestward, becoming a tropical storm on the 15th and hitting southeastern India as a 50 mph storm that night. It rapidly dissipated over land.
65 mph Tropical Storm Five, which developed on October 30 in the Bay of Bengal, made landfall at Nellore on the 2nd, dissipating shortly thereafter. 50 people and 26,000 cattle were reported to be died and 700,000 people were affected by the storm.
The monsoon trough spawned a tropical depression on November 8 in the southeastern Bay of Bengal. It tracked northward, then turned westward, strengthening to a 60 mph tropical storm before hitting eastern India on the 12th.
Tropical Storm Seven, which developed in the western Bay of Bengal on December 2, strengthened in the eastern Arabian Sea to a 50 mph storm. It turned to the northeast, where upper-level winds weakened it to a tropical depression. The depression hit western India, 90 miles south of Bombay, on the 12th, and dissipated the next day without causing any damage.
The eighth and final storm of the season formed on December 17 northeast of Sri Lanka. It moved westward, and executed an elongated loop lasting 4 days. It briefly reached tropical storm strength before vertical shear weakened it again, and the system hit eastern India on the 23rd.
During the season, the JTWC monitored two systems which were not recognized as tropical cyclones by the IMD.
