An average Atlantic hurricane season features 12 tropical storms, 6 hurricanes, and 3 major hurricanes, and features an Accumulated Cyclone Energy (ACE) count of 106. The 1999 Atlantic hurricane season had five
An average Pacific hurricane season features 15 tropical storms, 9 hurricanes, and 4 major hurricanes, and features an Accumulated Cyclone Energy (ACE) count of 132. The season produced fourteen tropical cyclones and nine
The average typhoon season lasts year-round, with the majority of the storms forming between May and October. An average Pacific typhoon season features 26 tropical storms, 16 typhoons, and 9 super typhoons (unofficial category). It also features an average Accumulated Cyclone Energy (ACE) count of approximately 294; the basin is typically the most active basin for tropical cyclone formation. However, it was a very inactive season, featuring the lowest number of typhoons on record, five.
The 1999 Pacific typhoon season was the last Pacific typhoon season to use English names as storm names. In the season, there were 45 tropical depressions, in which 20 strengthened to tropical storms, of 5 further strengthening into a typhoon. Typhoon Bart was the only
The season produced an average number of storms but there was an above average number of intense cyclones. In May, a Category 3 cyclone struck Pakistan, leaving at 700 people dead or missing. In October, two very intense cyclones struck eastern India within two weeks of each other, leaving over 10,000 people dead and causing more than $4.5 billion (1999 USD) in damages.
A total of ten tropical cyclones were observed. The

, especially in North Carolina. Damage from the storm totaled approximately $6.5 billion (1999 USD) and there were at least 77 fatalities, making it the deadliest hurricane in the United States since Hurricane Agnes in 1972. Flooding from Floyd in North Carolina followed Hurricane Dennis, a slow and erratic–moving storm that dropped heavy rainfall in the eastern portion of the state. Tropical Depression Eleven in October contributed to extreme flooding in Mexico, which left 636 people dead and caused $491.3 million in damage, though impact could not be distinguished from the storm itself. Hurricane Irene caused extensive flooding in Cuba and Florida, with lesser effects in the Bahamas and North Carolina. Irene was the second–costliest storm of the season, with about $800 million in damage. Hurricane Lenny was an unusual eastward–moving storm in the Caribbean Sea and a strong late–season storm. It caused extensive damage in the Lesser Antilles in the month of November.
Eastern and Central Pacific Ocean
An average Pacific hurricane season features 15 tropical storms, 9 hurricanes, and 4 major hurricanes, and features an Accumulated Cyclone Energy (ACE) count of 132. The season produced fourteen tropical cyclones and nine named storm

s, which was well below the average of sixteen named storms per season; this was largely due to a strong La Niña taking over much of the Pacific.
However, the total of six hurricanes and two major hurricanes during the season was near the averages of eight and three, respectively. Although it remained offshore, Hurricane Adrian caused 6 deaths from flooding and rough surf in Mexico. Hurricane Dora was a long-lived and intense cyclone, which had the second-longest track of a Pacific hurricane on record. The storm brought minor impacts to the island of Hawaii; however, no deaths or damage was reported. The deadliest tropical cyclone, Hurricane Greg, killed 10 people from flooding in Mexico.
Western Pacific Ocean
The average typhoon season lasts year-round, with the majority of the storms forming between May and October. An average Pacific typhoon season features 26 tropical storms, 16 typhoons, and 9 super typhoons (unofficial category). It also features an average Accumulated Cyclone Energy (ACE) count of approximately 294; the basin is typically the most active basin for tropical cyclone formation. However, it was a very inactive season, featuring the lowest number of typhoons on record, five.
The 1999 Pacific typhoon season was the last Pacific typhoon season to use English names as storm names. In the season, there were 45 tropical depressions, in which 20 strengthened to tropical storms, of 5 further strengthening into a typhoon. Typhoon Bart was the only super typhoon

The season produced an average number of storms but there was an above average number of intense cyclones. In May, a Category 3 cyclone struck Pakistan, leaving at 700 people dead or missing. In October, two very intense cyclones struck eastern India within two weeks of each other, leaving over 10,000 people dead and causing more than $4.5 billion (1999 USD) in damages.

January–June
Activity began late, with the first tropical storm – Alda – forming on January 16, the third latest ever recorded at the time. Alda formed in the Mozambique Channel, which was one of few favorable areas for tropical cyclogenesis in the season. It brought rainfall to southwestern Madagascar that alleviated previously dry conditions. The next five tropical storms either originated or crossed into the adjacent Australian basin, where storms were monitored by the Bureau of Meteorology (BoM). Both Tropical Storm Chikita and Tropical Cyclone Davina brought beneficial rainfall to the Mascarene Islands. The latter storm caused two drowning deaths on Réunion and caused some crop damage. The strongest storm – Evrina – peaked as a strong cyclone in the Australian but weakened upon crossing 90°E, with 10-minute maximum sustained winds of in the basin. The final storm was unnamed, crossing from the Australian basin on April 21 as a minimal tropical storm before quickly dissipating. There were also several tropical disturbances or depressions, many short-lived. The first of these formed on September 3 in the northeastern portion of the basin, and there was a tropical depression in February in the Mozambique Channel that approached tropical storm status.July–December
Despite the destructive nature of the season, it began later than usual. Cyclone Astride originated toward the end of December, bringing rainfall and gusty winds to northern Madagascar while in the region.Australian Region

During the season the most intense tropical cyclone was Severe Tropical Cyclone Cora, which had a minimum pressure of . After the season had ended the names Cora and Dani were retired from the naming lists, after they had caused significant impacts to South Pacific islands.
