The South Florida Water Management District's Tidal Outlook for the forecast period of September 28 through October 4, 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:
- Heightened Tidal Levels: The SFWMD’s weekly king tide forecast indicates that enhanced tidal conditions are expected through Wednesday next week. Initially, astronomical factors related to the full moon will enhance the tidal levels through the weekend. Early next week, swells generated by strong winds around an area of low pressure over the northwest Atlantic will arrive along the east coast of the SFWMD, further enhancing water levels through the middle part of next week.
- Coastal Flooding Risk: As a result of these factors, there is an increased likelihood of minor to moderate coastal flooding in the low-lying areas of coastal Martin, St. Lucie, Palm Beach, Broward, Miami-Dade and Monroe counties within the SFWMD region.
- Prolonged Coastal Flooding Threat: The combination of these meteorological, oceanographic, and astronomical factors will extend the threat of coastal flooding through the following week, up until Wednesday, October 4.

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)

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.
