The 2025 King Tide season has begun, and the South Florida Water Management District (District) will publish a weekly Tidal Outlook to keep you informed this season. These outlooks begin today, September 1, and will continue to be shared every Monday throughout the season. The updates are intended to inform interested stakeholders and the public.
King Tides are driven by the variations in the strength and direction of the moon's gravitational pull, especially during new and full moon phases in the fall. The King Tide outlooks provide information on conditions – such as wind strength and direction, ocean currents – that can cause tides to rise or fall beyond predicted levels. The District continues its efforts to monitor, respond to, and document these events.
With approximately 700 miles of shoreline and more than 40 gravity coastal structures upstream of tidally influenced canals, the District's water management mission is influenced by sea levels. Alongside rainfall and storm surge, high tide events also contribute to flood risks in South Florida.
The National Oceanographic and Atmospheric Administration predicts high tides will peak along South Florida's coast during the following days(peaks vary by location). During these periods, high tides will approach the National Weather Service (NWS) "Minor Flooding" threshold.
- September 6-12 (Full Moon)
- September 19-25 (New Moon)
- October 3-25 (Full and New Moon)
- November 1-10 ((Full Moon)
- November 18-20 (New Moon)
- December 2-7 (Full Moon)
Enhanced Tidal Forecast in Partnership with University of Miami
In 2022, SFWMD partnered with the University of Miami (UM) Rosenstiel School of Marine, Atmospheric, and Earth Science partnered in 2022 to improve tide predictions from the NOAA. These enhanced predictions, featured in the Weekly Tidal Outlook Forecast, incorporate dynamic model inputs that account for sea level rise, meteorological conditions, and oceanic factors such as wind, wind direction, sea surface temperature, and swell energy.
Automated king tide forecasts are now accessible through SFWMD’s Resilience Metrics Hub for the following seven tidal stations along South Florida’s east and west coasts:
- Virginia Key
- Port Everglades
- Lake Worth
- Key West
- Vaca Key
- Naples/Naples Bay North
- Fort Myers
