The 2004 North Indian Ocean cyclone season was the first in which tropical cyclones were officially named in the basin. Cyclone Onil, which struck India and Pakistan, was named in late September. The final storm, Cyclone Agni, was also named, and crossed into the southern hemisphere shortly before dissipation. This storm became notable during its origins and became one of the storms closest to the equator. The season was fairly active, with ten depressions forming from May to November. The India Meteorological Department designated four of these as cyclonic storms, which have maximum sustained winds of at least 65 km/h (40 mph) averaged over three minutes. The Joint Typhoon Warning Center also issued warnings for five of the storms on an unofficial basis.
In early May, two tropical storms formed in the basin The first formed on May 5 and meandered while intensifying, dropping 1,840 mm (72 in) in Aminidivi in the Lakshadweep group offshore western India, which was the highest daily rainfall total in the basin. A week later, a cyclone – the strongest of the season – struck Myanmar, killing 236 people and leaving 25,000 people homeless. Depressions also formed on opposite sides of India in June. A depression in September killed 59 people after dropping torrential rainfall over Bangladesh and adjacent West Bengal. In October, another depression struck the region, killing 273 people. A short-lived cyclonic storm would form in the Arabian Sea in November.
