King Tides

What is a King Tide?

A King Tide is a higher-than-normal tide that typically lasts about 3 hours. King Tides occur annually and predictably; in September through November in Miami. King Tides may cause residents to experience "sunny day flooding" where a street or other areas will temporarily become flooded when it is not raining.

Where should I expect King Tide flooding?

High water levels caused by King Tides can cause flooding on streets or other areas near waterways and the coast. In addition, areas of the City at low elevation that are not coastal may also experience flooding during King Tides.
