Idalia isn’t hitting South Florida. But there may be flooding thanks to king tides
If you’ve been in South Florida for a while, you know that September doesn’t only mean hurricanes. It also marks the start of the annual cycle of high tides known as king tides.
And the convergence of Hurricane Idalia with king tide season has forecasters more concerned about flooding in soon-to-be impacted areas of Florida.
The National Hurricane Center predicts that the storm will hit somewhere along Florida’s Big Bend area early Wednesday as a Category 3 hurricane. Idalia will bring 115 mph sustained winds and up to 11 feet of storm surge. The heavily populated Tampa Bay area could see four to seven feet.

Here’s what you need to know about king tide and its effects on South Florida — even though Idalia won’t be hitting the region.
What is king tide?
King tide is when the tides are at the highest in the season. These high tides are a natural occurrence during new and full moons but are exacerbated by climate change. These tides can push sea levels a foot or two higher than normal, which causes flooding in low-lying spots along the east coast, like Miami.
During king tide season, streets in some residential areas of the Keys, including Florida Bay neighborhoods in Key Largo, are flooded to the point that residents can’t drive through them. One Keys neighborhood saw 90 straight days of flooded streets during 2019’s king tide season.
When will South Florida expect king tide?
King tides are expected in South Florida from Tuesday, Aug. 29 to Monday, Sept. 4. The tides are also predicted for Sept. 26-Oct. 3; Oct. 14-18; Oct. 25-Nov. 1; Nov. 13-15; and Nov. 25-28.
What should I know to stay safe during floods?
▪ Avoid walking through flood water because it can contain live electrical wires. It also contains pollutants that can be damaging to your health. If you need to, wash your hands and clothes after.
▪ Avoid driving through flooded areas. This can threaten your safety and damage your vehicle. Boaters should check the tide before leaving the dock. Bridges may have lower clearance.
▪ Check with your city government. They may have additional resources available.
▪ The city of Miami Beach offers free temporary parking during king tides if you live within the prescribed flood zone areas. Miami Beach residents can also report property and roadway flooding by calling 305-673-7625 or emailing flooding@miamibeachfl.gov.
▪ Anyone who notices standing water for more than 48 hours should call the Miami Beach control room at 305-673-7625. It is important to drain and cover standing water to avoid mosquito-borne disease.
