Chronic Tidal Flooding

Climate change is causing greater chronic tidal flooding in New York City’s low-lying coastal communities.

Climate change is causing greater chronic tidal flooding (also called sunny day flooding), which occurs when water from regular tides breach the land, even without storms. This impacts New York City’s low-lying coastal communities, and greater impacts are expected in the future due to increases in sea level. Sea level in New York City has already risen at least 18 inches since the 1850s and could rise as much as another 5.4 feet by 2100. Sections of the city’s coastline will be subject to daily tidal flooding by the 2050s. Some low-lying neighborhoods are already experiencing chronic tidal flooding due to astronomical high tides.
