Drivers and pedestrians in Coral Gables, South Miami and Pinecrest face flooded roads this week as king tides push high water onto low-lying streets through Aug. 14.
Mayor Daniella Levine Cava's administration warned residents Tuesday, Aug. 11, to watch for standing water and avoid driving through flooded intersections. The county directed residents to miamidade.gov/kingtides for updates and preparation tips.
The timing compounds an already hectic stretch for local families. Miami-Dade County Public Schools opens its 2026-27 school year Thursday, Aug. 13, the third day of the tidal event. Archdiocese of Miami Catholic schools, which include several campuses in the Coral Gables area, started classes Tuesday, Aug. 11, the same day the high water began.
What's Causing This Week's High Water
King tides are the highest predicted tides of the year, driven by the alignment of the sun and moon. This week's event coincides with a new moon phase, according to the South Florida Water Management District's 2026 forecast. Each high-water period typically lasts about three hours, though water levels can remain elevated 90 minutes to two hours before and after the peak.
The flooding can hit even on clear days. Known as "sunny day flooding," the phenomenon pushes water onto streets, sidewalks and parking areas near waterways and in low-elevation neighborhoods, even without rain. If king tides coincide with heavy rain or strong winds, flooding can worsen significantly.
Officials Warn: Never Drive Through Standing Water
County and municipal officials stress one rule above all: Do not drive through standing water. It takes less than 3 feet of water to float a car, and floodwater can hide debris or downed power lines. Six inches of fast-moving water is enough to knock a person off their feet.
More King Tides Expected Before Year's End
The Aug. 11-14 window is only the first of six king tide periods forecast for 2026. The next is Sept. 8-15, followed by events running through late December.
