The 2025 North Indian Ocean cyclone season featured several deadly tropical cyclones, including cyclones Senyar and Ditwah. The former, Senyar, was the first recorded cyclone to form in the Strait of Malacca, and it produced deadly floods across Indonesia, Thailand, and Malaysia, claiming over 1,501 lives. Also in November 2025, Cyclone Ditwah meandered near Sri Lanka for several days, killing 647 people in the country. The season itself saw an above-average number of depressions forming, and an average amount of cyclonic storms forming. Seasons have no official bounds, but cyclones tend to form between April and December, with the peak from May to November. However, this year, the first cyclone attained that strength on October 3rd. 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, four to five cyclonic storms form in this basin every season.
