SUBJECT: 2023Fall King Tide Season Update
Southeast Florida may experience higher than normal tides this week. Often referred toasKing Tide
season, King Tides are considered the highest tides of the year. In Miami Beach, fall high tides usually
occur during certain days during the months of September, October, and November. TheCity reviews
NOAA predictions to anticipate which days may reach thresholds that may result in ponding or flooding
in |uw�|yinQareas.
When King Tides rise to an elevation higher than the adjacent land, minor flooding is often exhibited.
Since Miami Beach is low-lying and near sea level, lower areas of the city arc, particularly vulnerable to
high tide flooding. Note that flooding can occur at other times during the year, and king tides may be
exacerbated bystorms, wind, and rainfall.
King Tide Season Preparations

City staff monitors the tidal elevations and responds to complaints in areas of flooding. The City deploys
emergency ternporary pump stations in the lowest lying neighborhoods where neighborhood
improvement projects and stormwater system upgrades have yet to been completed, Stormwater
Pumps are inspected, adjusted, and cleaned. The City also offers parking toresidents who are

King Tide Season Dates
Tidal levels are predicted by the National Oceanic and Atmospheric Administration (NOAA). The NOAA
Tides and Currents station map can be used to locate stations that provide water levels, meteorological
observations and current observations. The Virginia Key station is the closest NOAA Monitoring Site.
While these dates reflect the Current prediction for seasonal higher tides, greater than average tides can
occur anytime of the year under varying conditions such as wind and weather patterns. The relative
distances and positions of the sun, moon, and Earth all affect the size and magnitude of the tides.
