The 2024 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation. [1] The season has no official bounds, but 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, 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 releases unofficial advisories. On average, three to four cyclonic storms form in this basin every season. [2]
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). The names were selected by a new list from the Regional Specialized Meteorological Center in New Delhi by mid-2020. [3] 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 other basins, then it will retain its original name. The next eight available names from the List of North Indian Ocean storm names are below.

This is a table of all storms in the 2024 North Indian Ocean cyclone season. It mentions all of the season's storms and their names, duration, peak intensities according to the IMD storm scale, damage, and death totals. Damage and death totals include the damage and deaths caused when that storm was a precursor wave or extratropical low. All of the damage figures are in 2024 USD.
Tropical cyclones and subtropical cyclones are named by various warning centers to simplify communication between forecasters and the general public regarding forecasts, watches and warnings. The names are intended to reduce confusion in the event of concurrent storms in the same basin. Once storms develop sustained wind speeds of more than 33 knots, names are generally assigned to them from predetermined lists, depending on the basin in which they originate. Some tropical depressions are named in the Western Pacific, while tropical cyclones must contain a significant amount of gale-force winds before they are named in the Southern Hemisphere.
In the Indian Ocean north of the equator, tropical cyclones can form throughout the year on either side of the Indian subcontinent, although most frequently between April and June, and between October and December.
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.
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index.

The 2012 North Indian Ocean cyclone season was a very inactive season. The season had a very late start, with the first system forming in October. During the season, only five systems formed, of which only two became cyclonic storms. Both the storms made landfall, and they, along with the deep depressions, were responsible for 128 deaths and economic losses worth at least $56.7 million.

The 2019 North Indian Ocean cyclone season was the second most active North Indian Ocean cyclone season on record in terms of cyclonic storms, 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 also became 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 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.
The 2022 North Indian Ocean cyclone season was an event in the annual cycle of tropical cyclone formation. It was an above-average season in terms of depressions and average in terms of deep depressions, but slightly below average in terms of cyclonic storms. It was also the least deadly North Indian Ocean cyclone season since 1988, according to official data. The season's strongest tropical cyclone was Cyclone Asani, with maximum wind speeds of 100 km/h and a minimum barometric pressure of 982 hPa.

The 2023 North Indian Ocean cyclone season was an above-average and deadly season, becoming the deadliest season since 2017, mainly due to Cyclone Mocha. With nine depressions and six cyclonic storms forming, it became the most active season, featuring the second-highest accumulated cyclone energy (ACE) on record only behind 2019. It also had the most extremely severe cyclonic storms on record, tieing with 1999 and 2019. The North Indian Ocean cyclone season has no official bounds, but 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. However, a cyclone can form at any time during the year shown by an unnamed depression that affected Sri Lanka in January-February.
This timeline documents all of the events of the 2024 North Indian Ocean cyclone season. The scope of this article is limited to the North Indian basin. During the season, systems will be designated as tropical depressions by the India Meteorological Department (IMD). Since they run the Regional Specialized Meteorological Centre (RSMC) for the basin, they will assign names to tropical depressions which developed into tropical storms in the basin. The Joint Typhoon Warning Center (JTWC) also monitors the basin, issuing unofficial bulletins for tropical cyclones which form in the basin for military interests.
