High-tide flooding, often referred to as “king tides,” “nuisance,” or “sunny day” flooding, is becoming increasingly common due to years of sea level rise. High Tide Flooding (HTF) is defined as the overflow or excess accumulation of ocean water at high tide that covers low-lying areas, and typically occurs when tides reach anywhere from 1.75 to 2 feet above the daily average high tide and start spilling onto streets or bubbling up from storm drains. As sea level rise continues, damaging floods that happened decades ago only during a storm now happen more regularly, like during a full-moon or with a change in prevailing winds or currents.

High-tide flooding, sometimes called “nuisance” flooding, refers to relatively minor flooding of low-lying drainage systems, streets, and yards during regular high tide events (i.e., “king tides”).
