The 2005 North Indian Ocean cyclone season has 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 scope of this basin is limited to north of the Equator and west of the Malay peninsula. The IMD and JTWC monitor this basin. The Arabian Sea and Bay of Bengal make up this basin, abbreviated ARB and BOB, respectively.
In 2005, a total of twelve cyclonic disturbances were identified in North Indian Ocean, against a normal of fifteen. However, it was highest after 1992. Four of them became cyclonic storm in Bay of Bengal and were named, against a normal of five to six.[1]

In the second week of January, an area of convection persisted southeast of Sri Lanka. It organized into a tropical depression on January 8, but dissipated on the 10th due to vertical shear.

Just behind the previous storm, a trough of low pressure developed into a tropical depression on January 13. Located a few hundred miles east-southeast of Sri Lanka, it meandered to the west, becoming a Cyclonic Storm on the 15th. Like its predecessor, Hibaru dissipated southeast of Sri Lanka on the 17th. This is the first season with two systems forming in January. The formation of a cyclonic storm in the month of January over low latitude is very rare; the last such occurrence was in the year 1987 (30 Jan. – 4 Feb, over the Bay of Bengal).

An area of convection developed in the South China Sea on September 12. It moved west-northwestward, moving inland over Thailand on the 13th. It reached the Bay of Bengal on the 15th, and slowly developed. On September 17 it was upgraded to a tropical depression by the Indian Meteorological Department (but not by the JTWC), and on September 18 it became Cyclonic Storm Pyarr. The next day Pyarr made landfall, and on September 22 it dissipated over northwestern India.

Heavy rains from the storm caused significant flooding in India. At least 100 people were killed, 50,000 were evacuated, and over 100,000 others were affected.[4]

The Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert early on November 27 on a low pressure system with persistent convection around its center not far from the Andaman Islands in the Bay of Bengal. At 2100Z that same day, about 100 n mi west of Port Blair, the JTWC upgraded the low pressure to a tropical depression, with the Indian Meteorological Department following suit the next day. It was upgraded into a tropical storm on the JTWC's following advisory at 0900Z on November 28. On November 28, the official RSMC in New Delhi upgraded the tropical storm to Baaz. The storm eventually dissipated as a significant tropical cyclone over sea near or north of Chennai. Baaz refers to the Saker Falcon in Arabic.

Tropical Storm 06B formed 550 nautical miles (1,020 km) east of Chennai on December 6, west of the Andaman Islands. It became Cyclonic Storm Fanoos on December 7. However, Fanoos weakened into a deep depression prior to crossing north Tamil Nadu coast near Vedaranyam at 0530 UTC (1100 IST) December 10. Fanoos weakened further into a low pressure area over south Tamil Nadu coast next day. Its remnants entered Arabian Sea but regeneration did not occur. Fanoos means chandelier in Urdu.
Severe damage was reported in Sri Lanka where thousands of homes were either damaged or destroyed. Due to the quick weakening prior to landfall, only minor damage occurred in Tamil Nadu. However, heavy rains forced the evacuation of 30,000 residents in the area. No fatalities were reported from Fanoos.[5]
