What US cities will be flooded by 2050?

Written by Editorial Team | Last Updated: August 2026

Climate change projections and rising sea-level modeling indicate that numerous coastal United States cities face severe flooding risks by the year 2050. Low-lying coastal metropolitan areas, particularly along the Atlantic and Gulf coasts, are especially vulnerable due to land subsidence, stronger storm surges, and regular tidal flooding events commonly known as sunny-day or nuisance flooding. Prominent cities frequently highlighted in scientific assessments include Miami and Miami Beach in Florida, New Orleans in Louisiana, Norfolk and Virginia Beach in Virginia, Charleston in South Carolina, and Galveston in Texas. Additionally, certain Pacific coastal regions and low-lying parts of major urban hubs like New York City, Boston, and San Francisco anticipate increasingly frequent inundation events that threaten critical infrastructure, residential zones, and local economic stability unless extensive coastal defenses and mitigation strategies are aggressively implemented over the coming decades.
