The 2019 North Indian Ocean cyclone season was the most active season in the basin, beating 1992, with eleven depressions and eight cyclones. It was also the most destructive on record, one of the deadliest on record, and the only one on record to have two Category 5 landfalls. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and December, with the two peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean.
The scope of this article is limited to the Indian Ocean in the Northern Hemisphere, east of the Horn of Africa and west of the Malay Peninsula. There are two main seas in the North Indian Ocean — the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD.
The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center (JTWC) and the National Meteorological Center of CMA (NMC) unofficially release full advisories. On average, three to four cyclonic storms form in this basin every season.
