# Charleston king tides and high water in 2023

> In 2023, NOAA's Charleston tide gauge recorded water high enough for FloodRoute's model to put at least one Charleston road at risk on 64 days. The highest was 9.64 ft on Sunday, December 17, 2023, 3.86 ft above the tide tables, with 311 roads at risk, including Cherry Street, Courtenay Drive and Colonial 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.
