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.
Below is a timeline of the 2007 North Indian Ocean cyclone season, documenting major events with regards to tropical cyclone formation, strengthening, weakening, landfall, extratropical transition, as well as dissipation. The 2007 North Indian Ocean cyclone season was an ongoing event in the annual cycle of tropical cyclone formation.
Deep Depression BOB 03 and Cyclonic Storm Yemyin were a pair of deadly tropical cyclones that made landfalls on India and Pakistan in June 2007. The Pakistan Meteorological Department referred to both as Tropical Cyclone 03B, naming it "Tropical Cyclone Yemyin". At the time, the official WMO body responsible for tropical cyclones in the Arabian Sea, the India Meteorological Department (IMD), did not name them. However, the IMD reassessed the second system to have reached cyclonic storm strength, and retroactively named it Yemyin.
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 2000 North Indian Ocean cyclone season was fairly quiet compared to the year before, 1999 North Indian Ocean cyclone season, with all of the activity originating in the Bay of Bengal. The basin comprises the Indian Ocean north of the equator, with warnings issued by the India Meteorological Department (IMD) in New Delhi. There were six depressions throughout the year, of which five intensified into cyclonic storms – tropical cyclones with winds of 65 mph (105 km/h) sustained over 3 minutes. Two of the storms strengthened into a Very Severe Cyclonic Storm, which has winds of at least 120 km/h (75 mph), equivalent to a minimal hurricane. The Joint Typhoon Warning Center (JTWC) also tracked storms in the basin on an unofficial basis, estimating winds sustained over 1 minute.
The 1998 North Indian Ocean cyclone season was an active season in annual cycle of tropical cyclone formation. The season has no official bounds but cyclones tend to form between April and December.

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 2008 North Indian Ocean cyclone season officially ran throughout the year during 2008, with the first depression forming on April 27. The timeline includes information that was not operationally released, meaning that information from post-storm reviews by the Joint Typhoon Warning Center (JTWC), and the India Meteorological Department (IMD), such as information on a storm that was not operationally warned on. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation's during the 2008 North Indian Ocean cyclone season.
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 1985 North Indian Ocean cyclone season was part of the annual cycle of tropical cyclone formation. The season has no official bounds but cyclones tend to form between April and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. 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 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 season was an average one, seeing four named storms, with one further intensifying into a very severe cyclonic storm. The first named storm, Roanu, developed on 19 May while the season's last named storm, Vardah, dissipated on 18 December.

These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began on April 2, when a depression designated as BOB 01 was formed in the north Andaman Sea and quickly made landfall in Myanmar. The basin remained quiet for over a month before Cyclone Tauktae formed. It rapidly intensified into an extremely severe cyclonic storm before making landfall in Gujarat, become the strongest storm ever to strike that state since the 1998 Gujarat cyclone. Later that month, BOB 02 formed and later strengthened into Cyclone Yaas. Yaas rapidly intensified into a very severe cyclonic storm before making landfall in northwestern Odisha. The season's strongest tropical cyclone was Cyclone Tauktae, with maximum wind speeds of 185 km/h (115 mph) and a minimum barometric pressure of 950 hPa (28.05 inHg).
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 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.
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.
