South Florida is experiencing a series of king tides that are flooding streets, sidewalks and low‑lying neighborhoods. The tides, driven by a full moon and the Earth’s closest approach to the moon, are expected to persist through Thursday, Oct. 1.
What is a king tide?
A king tide is an exceptionally high tide that typically lasts about three hours. These tides occur during the full and new moons, when the lunar orbit brings the moon closest to Earth. The resulting surge can raise water levels enough to inundate areas that are normally dry.
Current impacts in South Florida
In Hollywood, residents were forced to walk through several inches of water along the Hollywood Broadwalk on Sunday. Video from local outlet Only in Dade captured the rising water as it lapped the promenade, turning a popular walking path into a temporary stream.
Other coastal and inland communities are seeing similar conditions. The porous limestone that underlies much of the region allows water to rise through the ground as the water table climbs, leading to street flooding even away from the shoreline.
Why the flooding is worsening
Sea‑level rise over the past decade has amplified the impact of king tides. Higher baseline water levels mean that each tidal surge starts from a higher point, increasing the likelihood of overflow onto roads and sidewalks. Residents have reported standing water in areas that have not seen rain, underscoring how the elevated water table alone can cause flooding.
What to expect
The current series of king tides will continue through early October, with the highest tides coinciding with the full moon. Water levels typically recede after the peak, but the lingering high water table can keep streets wet for hours after the tide has gone out.
Authorities advise residents to avoid low‑lying routes during peak tide times, watch local forecasts, and be prepared for temporary disruptions. Community groups are sharing real‑time updates on social media to help neighbors navigate the conditions safely.
Looking ahead
Experts note that as climate change drives further sea‑level rise, king tide events will become more frequent and more severe. While the current flooding is a seasonal phenomenon, it serves as a reminder of the long‑term challenges facing South Florida’s coastal communities.
For now, residents are urged to stay informed, exercise caution when traveling near water, and support local efforts to monitor and respond to the rising tides.
