Lucknow sits on the banks of the Gomti River in central Uttar Pradesh, where the June-to-September southwest monsoon delivers most of its annual rainfall after a long, hot, dry spring. Rapid urban growth has outpaced drainage infrastructure in many neighborhoods, so intense early-monsoon downpours often produce localized waterlogging on major roads before the city’s stormwater system catches up for the rest of the season.
