Brihanmumbai Municipal Corporation (BMC) issues a 2026 high-tide calendar for Mumbai and advises residents to stay away from the sea during periods of major tidal activity, particularly during bad weather and the monsoon season. The BMC warns that higher tides can increase flooding and waterlogging risks in low-lying coastal areas. The city is expected to see multiple high tides above 4.5 metres between June and September. The highest tide of the season is forecast for July 16, when sea levels are expected to reach about 4.89 metres. Several major high-tide periods are also projected for June 14–19 (around 4.64–4.87 metres), July 13–18 (up to about 4.89 metres), and August 12–16 (around 4.50–4.83 metres), with additional high-tide activity above 4.5 metres in September. The BMC asks citizens to follow advisories issued by the BMC, Mumbai Police and disaster-management agencies during the monsoon and to avoid unnecessary travel to seafront areas during rough conditions. Emergency and disaster response units are kept on alert during these periods.
