Rain season
Monsoon June–September; Patna's flooding risk goes beyond its own rainfall because the Ganga and Koshi rivers carry massive Himalayan runoff downstream from Nepal. August is the highest-risk month for serious inundation. Annual local rainfall is around 1,000mm, but above-average years can bring severe flooding from upstream.
