The '''1961 North Indian Ocean cyclone season''' had no bounds, but cyclones tend to form between April and December, with peaks in May and November. 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]] releases unofficial advisories. An average of four to six storms form in the North Indian Ocean every season with peaks in May and November.<ref name="IMD">{{cite web|url=http://www.imd.ernet.in/services/cyclone/tropical-cyclone.htm |title=IMD Cyclone Warning Services: Tropical Cyclones |publisher=[[India Meteorological Department]] |accessdate=May 10, 2013 |archiveurl=https://web.archive.org/web/20081104064430/http://www.imd.ernet.in/services/cyclone/tropical-cyclone.htm |archivedate=4 November 2008 |url-status=dead }}</ref> Cyclones occurring between the meridians [[45th meridian east|45°E]] and [[100th meridian east|100°E]] are included in the season by the IMD.<ref>{{cite web|publisher=India Meteorological Department |date=January 2009 |accessdate=May 10, 2013 |title=Report on Cyclonic Disturbances Over the North Indian During 2008 |url=http://www.imd.ernet.in/section/nhac/dynamic/rsmc.pdf |url-status=dead |archiveurl=https://web.archive.org/web/20090529004113/http://www.imd.ernet.in/services/cyclone/tropical-cyclone.htm |archivedate=May 29, 2009 }}</ref>
