The 2015 North Indian Ocean cyclone season was a below-average tropical cyclone season which featured the highest number of deaths since the 2010 season. Despite inactivity in the Bay of Bengal caused by the ongoing El Niño, the season produced an above-average number of tropical cyclones in the Arabian Sea. The first storm of the season, Ashobaa, formed on 7 June, while the final storm of the season, Megh, ultimately dissipated on 10 November.
