Below is a timeline of the 2008 North Indian Ocean cyclone season, documenting major events with regards to tropical cyclone formation, strengthening, weakening, landfall, extratropical transition, as well as dissipation. The 2008 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation.

For convenience and clarity, in the timeline below, all landfalls are bolded. Where the exact time of an event is unclear, "c." is used to denote the approximate time.

The India Meteorological Department (IMD) is the official Regional Specialized Meteorological Centre in this basin, while the Joint Typhoon Warning Center releases unofficial advisories.

Storms tracked by the JTWC are referred to numerically to avoid confusion, as the JTWC sometimes recognises a storm at a different intensity compared to the IMD.

The graphical bar above gives a brief overview of storm activity during the season, and a storm's maximum intensity category in terms of wind speed is included as a colour bar. This is given by the IMD's values of maximum 10-minute sustained winds. The colour scheme is detailed to the right.
