This week, southern Florida is bracing for potential flooding as the year’s largest full moon approaches, a phenomenon popularly known as king tides.
The National Weather Service (NWS) has issued a coastal flood advisory for areas including Broward, Miami-Dade, and Palm Beach counties, with the supermoon expected to illuminate the Northern Hemisphere beginning Wednesday night.
From Wednesday night through Friday evening, southeastern Florida faces a “moderate” risk of flooding. Similar coastal flood advisories have been issued for the Jacksonville area, the Texas Gulf Coast, and parts of North Carolina’s coastline. Additionally, there’s a notable rip current risk for southeastern Florida lasting through Sunday evening.
The NWS highlights the possibility of exceptionally high tides due to the alignment of the sun, moon, and Earth, which enhances gravitational forces and elevates ocean levels significantly.

The Florida Keys are also under a coastal flooding statement, with the most severe flooding conditions anticipated from Wednesday into early next week, according to the NWS’s recent social media updates.
The NWS advises that “flooding may impact low-lying parking lots, coastal roads, and parks around high tide.” They caution against parking in these vulnerable areas as saltwater can seriously damage vehicles.

For those living in flood advisory zones in southwestern Florida, travel precautions are advisable. The NWS urges residents to “allow extra time” for commutes and to avoid driving around barricades or through unfamiliar waters. It’s also recommended to take proactive measures to protect flood-prone property.
During these times of heightened rip current risks, the public is urged to swim near lifeguards. If caught in a rip current, the NWS provides helpful tips: relax and float, don’t swim against the current, and if possible, swim parallel to the shore. If escape proves difficult, facing the shore and signaling for help is advised.
As meteorologist Garcia puts it, “The moon influences the tides, and with a northeasterly wind pushing water toward the coast, it’s akin to being in a bathtub where water is continually being shoved in one direction.” The result? Increased water levels along the coast.
