The South Florida Water Management District's Tidal Outlook for the forecast period of October 27 through November 1, 2023 has been updated. We want to keep you informed about the latest developments regarding our king tide forecast. Here's what you need to know:
-
Coastal Flooding Risk: Minor to moderate coastal flooding at high tide is already occurring along the east coast of the SFWMD and the Florida Keys due to a combination of the upcoming Full Moon on Saturday, October 28, swells from Post-Tropical Cyclone Tammy, relatively strong northeasterly winds, and very warm ocean temperatures. These tidal conditions are expected to continue through the weekend.
-
Heightened Tidal Levels: Water levels could rise even higher during early-to-mid next week if an area of low pressure develops over the north-central Caribbean Sea or near the Bahamas. The development of this feature, especially if it becomes a tropical cyclone, would generate swells that would be directed south-southwestward along the east coast of the SFWMD's region, possibly resulting in the greatest high tides since Hurricane Nicole last November.

SFWMD is continuing efforts for the monitoring, operational response and documentation of these events. These weekly updates are intended to be informational for interested stakeholders and the public. If conditions warrant, additional updates may be issued throughout the forecast period.

High tides are predicted by the National Oceanographic and Atmospheric Administration (NOAA) to peak above 2.5-3 feet Mean Lower Low Water (MLLW) along the South Florida Coast during the following days in 2023 (peak varies by location):
- September 13-15 (New Moon)
- September 26 to October 4 (Full Moon)
- October 14-19 (New Moon)
- October 24 to November 2 (Full Moon)
- November 11-17 (New Moon)
- November 24-29 (Full Moon)
To help guide water management decisions, SFWMD has launched a weekly Tidal Outlook Forecast, published every Monday, to report conditions – such as wind strength and direction, ocean currents – that can cause tides to occur higher or lower than predicted at certain locations.
