The 2005 North Indian Ocean cyclone season caused much devastation and many deaths in Southern India despite the storms’ weakness. The basin covers the Indian Ocean north of the equator as well as inland areas, sub-divided by the Arabian Sea and the Bay of Bengal. Although the season began early with two systems in January, the bulk of activity was confined from September to December. The official India Meteorological Department tracked 12 depressions in the basin, and the unofficial Joint Typhoon Warning Center (JTWC) monitored two additional storms. Three systems intensified into a cyclonic storm, which have sustained winds of at least 63 km/h (39 mph), at which point the IMD named them.
The 1992 North Indian Ocean cyclone season was unofficially the most active year on record for the basin, with 10 tropical storms developing, according to the Joint Typhoon Warning Center (JTWC). 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 JTWC releases unofficial advisories. An average of four to six storms form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.
The 2006 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.
The 2007 North Indian Ocean cyclone season was one of the most active North Indian Ocean cyclone seasons on record. The North Indian Ocean cyclone season has no official 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.
The 1970 North Indian Ocean cyclone season had no bounds, but tropical cyclones in the North Indian Ocean tend to form between April and December, with peaks in May and November. The 1970 season saw a total of seven cyclonic storms, of which three developed into severe cyclonic storms. The Bay of Bengal was more active than the Arabian Sea during 1970, with all of the three severe cyclonic storms in the season forming there. Unusually, none of the storms in the Arabian Sea made landfall this year. The most significant storm of the season was the Bhola cyclone, which formed in the Bay of Bengal and hit Bangladesh on November 12. The storm killed at least 500,000, making it the deadliest tropical cyclone in recorded history. The season was also the deadliest tropical cyclone season globally, with 500,805 fatalities, mostly due to the aforementioned Bhola cyclone.
The 2003 North Indian Ocean cyclone season was the last season that tropical cyclones were not publicly labeled by India Meteorological Department (IMD). Also was mostly focused in the Bay of Bengal, where six of the seven depressions developed. The remaining system was a tropical cyclone that developed in the Arabian Sea in November, which was also the only system that did not affect land. There were three cyclonic storms, which was below the average of 4–6. Only one storm formed before the start of the monsoon season in June, although it was also the most notable. On May 10, a depression formed in the central Bay of Bengal, and within a few days became a very severe cyclonic storm. After it stalled, it drew moisture from the southwest to produce severe flooding across Sri Lanka, killing 254 people and becoming the worst floods there since 1947. Damage on the island totaled $135 million (2003 USD). The storm eventually made landfall in Myanmar on May 19. It is possible that the storm contributed to a deadly heat wave in India due to shifting air currents.
The 2002 North Indian Ocean cyclone season was a below average season in terms of tropical cyclone formation. The season had no official bounds, but most storms formed in either May or after October. No depressions or storms formed during the monsoon season from July to September, the first such instance on record. 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 four to six storms form in the North Indian Ocean every season with peaks in May and November. Cyclones occurring between the meridians 45°E and 100°E are included in the season by the IMD.
The 1996 North Indian Ocean cyclone season featured several deadly tropical cyclones, with over 2,000 people killed during the year. The India Meteorological Department (IMD) – the Regional Specialized Meteorological Center for the northern Indian Ocean as recognized by the World Meteorological Organization – issued warnings for nine tropical cyclones in the region. Storms were also tracked on an unofficial basis by the American-based Joint Typhoon Warning Center, which observed one additional storm. The basin is split between the Bay of Bengal off the east coast of India and the Arabian Sea off the west coast. During the year, the activity was affected by the monsoon season, with most storms forming in June or after October.
The 1990 North Indian Ocean cyclone season featured a below average total of twelve cyclonic disturbances and one of the most intense tropical cyclones in the basin on record. During the season the systems were primarily monitored by the India Meteorological Department, while other warning centres such as the United States Joint Typhoon Warning Center also monitored the area. During the season, there were at least 1,577 deaths, while the systems caused over US$693 million in damages. The most significant system was the 1990 Andhra Pradesh cyclone, which was the most intense, damaging, and the deadliest system of the season.
The 1993 North Indian Ocean cyclone season was the least active on record in the basin, with only four tropical disturbances. 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. The India Meteorological Department (IMD) issued advisories for the systems in its official capacity as the local Regional Specialized Meteorological Center, while the Joint Typhoon Warning Center also issued advisories for two of the storms on an unofficial basis. Of the five disturbances tracked by the IMD, two intensified into cyclonic storms.
The 1994 North Indian Ocean cyclone season was a below-average year in which eight tropical cyclones affected seven countries bordering the North Indian Ocean. The India Meteorological Department tracks all tropical cyclones in the basin, north of the equator. The first system developed on March 21 in the Bay of Bengal, the first March storm in the basin since 1938. The second storm was the most powerful cyclone of the season, attaining maximum sustained winds of 215 km/h (135 mph) in the northern Bay of Bengal. Making landfall near the border of Bangladesh and Myanmar, the cyclone killed 350 people and left US$125 million in damage.
The 2011 North Indian Ocean cyclone season was the least active tropical cyclone season in the North Indian Ocean since 1993. Only two cyclonic storms formed, below the average of four to six. The North Indian Ocean cyclone season has no official 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. 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.
India is a country in the North Indian Ocean that is the most vulnerable to getting hit by tropical cyclones in the basin, from the east or from the west.On average, 2–3 tropical cyclones make landfall in India each year, with about one being a severe tropical cyclone or greater.
The 1960 North Indian Ocean cyclone season featured two deadly tropical cyclones that killed approximately 20,000 people collectively in East Pakistan. The Indian subcontinent divides the North Indian Ocean into two areas: the Bay of Bengal to the east and the Arabian Sea to the west. The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department (IMD), while the Joint Typhoon Warning Center releases unofficial advisories. On average, five storms form in the North Indian Ocean every season with dual peaks in activity during May and November. Cyclones that occurred between 45°E and 100°E were included in seasonal records by the IMD.

The 2019 North Indian Ocean cyclone season was the most active North Indian Ocean cyclone season on record, in terms of cyclonic storms, however the 1992 season was more active according to the Joint Typhoon Warning Center. The season featured 12 depressions, 11 deep depressions, 8 cyclonic storms, 6 severe cyclonic storms, 6 very severe cyclonic storms, 3 extremely severe cyclonic storms, and 1 super cyclonic storm, Kyarr, the first since Cyclone Gonu in 2007. Additionally, it was also the third-costliest season recorded in the North Indian Ocean, only behind the 2020 and 2008 seasons.
The 2020 North Indian Ocean cyclone season was the costliest North Indian Ocean cyclone season on record, mostly due to the devastating Cyclone Amphan. The North Indian Ocean cyclone season has no official bounds, but cyclones tend to form between April and November, with peaks in late April to May and October to November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on May 16 with the designation of Depression BOB 01 in the Bay of Bengal, which later became Amphan. Cyclone Amphan was the strongest storm in the Bay of Bengal in 21 years and would break Nargis of 2008's record as the costliest storm in the North Indian Ocean. The season concluded with the dissipation of Cyclone Burevi on December 5. Overall, the season was slightly above average, seeing the development of five cyclonic storms.
