# Boston king tides and high water in 2024

> In 2024, NOAA's Boston tide gauge recorded water high enough for FloodRoute's model to put at least one Boston road at risk on 64 days. The highest was 14.41 ft on Saturday, January 13, 2024, 2.99 ft above the tide tables, with 112 roads at risk, including Chelsea Street, William T. Morrissey Boulevard and Marginal 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.
