The 2026 North Indian Ocean cyclone season is the ongoing annual cycle of tropical cyclone formation in the North Indian Ocean basin. The season has no official bounds, but most cyclones tend to form between April and December, with the peak from May to 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 as BOB. The systems that form over land are abbreviated as LAND.

The official Regional Specialized Meteorological Centre in this basin is the IMD, while the Joint Typhoon Warning Center (JTWC) releases unofficial advisories. On average, three to four cyclonic storms form in this basin every season.^[1]

Season summary

Systems

Other systems

On 7 January 2026, a low-pressure area intensified into a depression over the Bay of Bengal.^[2] It then further intensified into a deep depression on the morning of 8 January while moving west-northwestwards.^[3] The system made landfall over Sri Lanka as a depression and crossed the country before weakening into a well marked low pressure area in the Gulf of Mannar on 10 January.

Storm names

Within this basin, a tropical cyclone is assigned a name when it is judged to have reached cyclonic storm intensity with winds of 65 km/h (40 mph). There is no retirement of tropical cyclone names in this basin as the list of names is only scheduled to be used once before a new list of names is drawn up. Should a named tropical cyclone move into the basin from the Western Pacific, then it will retain its original name. The next eight available names from the list of North Indian Ocean storm names are below.^[4]
