A “King Tide” is a phrase for very high tides. These occur when there is a new or full moon lined up with the Earth and sun and when the moon is closest to the Earth during its orbit. The fall season in the Northeast further intensifies the tides due to warmer, expanding ocean water and changes in weather patterns. The tides will be higher from October 26-31. Boston will expect to see its highest tide on Tuesday October 29th, 2019 at 12:35pm.
Help document King Tides and storm damage. To do this, go to SciStarter.org/NOAA and create an account. Next, click the MyCoast icon to get started. MyCoast allows citizen scientists to submit images, damage reports, and location about king tides and storm damage. These reports are then given to state coastal resource managers to aid them in making plans to clean up the damage or learn what areas need to be protected for future flooding events.
Sunny day flooding or nuisance flooding occurs at high tide without precipitation. This can be intensified by King Tides (extremely high tides). With 40% of the American population living by the coast, these flooding events cause major social, economic and environmental impacts by interrupting businesses, damaging transportation, buildings, and the coastal environment. High tide flooding has increased in the U.S. on average by about 50 percent since 20 years ago and 100 percent since 30 years ago. These events are becoming more common due to ea level rise, which increases the risk to coastal communities with regular tidal flooding, increased vulnerability from storm surges from hurricanes and increased coastal erosion.
