King Tide Coming Soon
King Tide Season starts in September and will continue through December. King Tides (formally known as perigean spring tides) are the highest high tides of the year which normally occur during the autumn months of the year in our area. These high tides can cause overtopping of seawalls and can even cause brackish or saltwater to bubble up through storm drains. If you want to learn more, watch this King Tide PSA. The Department of Public Works has installed many tidal check valves which stop the water from coming in through stormwater outfalls, but there are still areas in which this water can approach more inland areas through our stormwater system and over seawalls.
This year’s predicted King Tide dates (based on Port Everglades NOAA station) are:
- September 9 – 11
- October 5 – 11
- November 3 – 9
- December 2 – 7
- Since higher tides are possible on both the new and full moon, additional dates to watch for tidal impacts include September 18- 22 and November 18-19.
As usual, the peak of King Tide is expected during the October dates.
Please know that the City has a number of flood related resources on our website and that you can direct residents who have questions about flood insurance, flood zones, etc. to this resource. Staff uses flooding reports made via the MyHB app as data to inform vulnerability assessments and flood mitigation projects. Additionally, you can document the flooding location at the Broward County Document the Floods Crowdsourcing Map.
Recurring floods like King Tides provide a likely test-run for our City for sea-level rise scenarios. As sea level rises, the frequency of King Tides are expected to increase in our area to nearly 50 times per year by 2030 and over 200 times per year by 2045.
