Broward County King Tide

King Tides

 

“Sunny Day Flooding” can also occur due to the highest tides of the year, which are also commonly refered to as King Tide events. Low-lying coastal areas of Broward County can be impacted by such flooding. These events often occur during the fall (August-November) with the peak tides usually occurring in October. Twice a day these tides will be so high that they can cause ocean water to back flow through drainage pipes, flow over sea walls, or even up through the ground due to the higher water pressure. These flooding conditions can last for several hours and can be very damaging to property, such as cars, due to corrosion from the saltwater. ​

King tides can be particularly dangerous and lead to significantly higher flooding if a high rainfall event occurs during the same time. An even higher threat of flooding can also occur during this time during a tropical storm or hurricane due to the associated wind and storm surge risks.

Calling all citizen scientists! Are you interested in helping document tidal flooding in our community? Both groups and individuals can help. If you are interested in "adopting" a site to monitor and report, please email resilience@broward.org.

 

 

The table below summarizes the predicted peak dates and heights for 2018, in feet above North American Vertical Datum (NAVD). As a reference, the average high tide for this location in 2018 is 0.32 feet NAVD.

​​Date​ Prediction (Ft)​ Date​  P​rediction (Ft. NAVD)​
​9/9/2018 ​1.3 ​10/9/2018 1.4
​9/10/2018 ​1.3 ​10/10/2018 1.4
​9/11/2018 ​1.3 ​10/11/2018 ​1.3
​10/8/2018 ​1.4 ​11/7/2018 ​1.3
These predictions are based on the South Port Everglades Tidal Station ​operated by NOAA. This is the closest station that will be fully monitored in 2018. This operational station gives up to date tidal information, wind speed/direction and temperature data.                                 
 

In addition, NOAA extrapolates predicted tides throughout various sites in Broward County. In the map below, please click on a station name to be redirected to that stations specific predictions that are offset for height and timing for that location. Note that these predictions are based on gravitational forces only and that offshore weather (winds, currents, and/or storms) often will magnify or diminish predicted tides.
