Streets turned into shallow rivers this week as the sea pushed well beyond its usual reach. For many residents, getting around meant wet shoes and a hard reminder of how close the water really sits.
How high did the king tide climb in South Florida?
Early signs point to this week’s king tide as the highest in South Florida’s history. Strong onshore winds pushed water toward the coast while full moon tides added even more lift, a combination that left low lying areas exposed. A king tide is an unusually high tide that happens when the sun and moon align with Earth, and it already tends to cause trouble on its own. This time, the wind turned a nuisance into something far bigger.
Wind matters more than many people realize. When it blows steadily toward shore, it stacks water against the coastline and slows its return to the sea. That is why a tide that is already high can feel so much bigger once the breeze joins in.
Seawater surged onto the coast, covering sections of Ocean Boulevard and other major roads between Miami and West Palm Beach. Both Fort Lauderdale and Miami peaked on Tuesday, Oct. 27, with water about 2.5 feet above the average high tide level, which is classified as major flooding. Major flooding is the most serious tier in the system used to rank coastal floods, and it signals widespread disruption.
What makes this flood so unusual?
Here is what makes the episode so striking. There is no hurricane and no nor’easter in the picture. A low pressure system sent winds onshore across South Florida just as a large fall tide arrived, and the two worked together. For perspective, Hurricane Irma pushed about 3.6 feet of water above high tide at Virginia Key. This week’s peak was lower, yet it came without any major storm to blame, which is exactly why the flooding feels so surprising.
What did residents face on the ground?
Along the coast, the water made itself at home. One resident had to cross the Las Olas Bridge in soaked socks to get back to the house, a scene that captured the mood of the day. Many of those who live in the hardest hit areas are worried that the problem will return year after year unless the city steps in with real solutions…
