Calling all citizen scientists! Are you interested in helping document tidal flooding in our community? Both groups and individuals can help. If you have a community group and want to "adopt" a site to monitor and report, download and read the King Tides Initiative Citizen Science Guidebook and then submit a Group Signup Form. Individuals do not need to sign up. You can participate by uploading photos of flooding you observe in your neighborhood or community. Use the web-mapping application to upload your photos directly from your smart phone.

Low-lying coastal areas of Broward County can be impacted by flooding from high tide events. These often time occur during the fall (August-November) with the peak usually occurring the King Tide (Highest tide of year) in October. The below table summarizes the peak dates and heights by month for 2017, in feet above mean lower low water (MLLW). As a reference, the average high tide for this location in 2017 is 2.18 ft.

 

​​Date​ Prediction (Ft)​ Date​  P​rediction (Ft)​
​9/19/2017 ​2.8 ​10/7/2017 ​2.9
​9/20/2017 ​2.8 ​10/8/2017 ​2.9
​9/21/2017 ​2.8 ​11/5/2017 ​3.0
​10/6/2017 ​2.9​ ​12/4/2017 ​2.8

These are based on the Virginia Key Tidal Station operated by NOAA, the closest station that is fully monitored.  For a complete summary of high tide predictions throughout the year see below links for Virginia Key and Andrews Ave:

In addition, NOAA extrapolates predicted tides throughout various sites in Broward County. 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.
