# New York City king tides and high water in 2021

> In 2021, NOAA's tide gauge at The Battery recorded water high enough for FloodRoute's model to put at least one New York City road at risk on 40 days. The highest was 7.79 ft on Monday, February 1, 2021, 3.22 ft above the tide tables, with 21 roads at risk, including Monroe Street, South Street and Madison Street.

**Estimates, not records of actual flooding.** Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions.
