The 1975 North Indian Ocean cyclone season was at the time, the most active cyclone season on record until it was beaten out 12 years later. 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.{{cite web|publisher=India Meteorological Department |year=2012 |accessdate=June 8, 2012 |title=Frequently Asked Questions: What is the annual frequency of Cyclones over the Indian Seas?
