King Tide: A Force of Nature

On Feb. 10, 2024, NepRWA staff and Greenway Council members gathered at Tenean Beach in Dorchester to observe the King Tide, one of the year’s highest tides, and get a glimpse into the future impacts of climate change. View event photos.

Even before high tide, water flooded the Greenway trail and much of the playground parking lot, reaching approximately 2 feet above the typical shoreline.

NepRWA is working to enhance Neponset Estuary resilience by collecting data on the salt marshes, developing better flood risk models, and developing a restoration plan to help stave off the worst impacts of coastal flooding. In addition, we are committed to collaborating with local community groups and neighborhood associations through our Community Advisory Council.

What is a King Tide? “A King Tide is a popular, non-scientific term people often use to describe exceptionally high tides.

Tides are long-period waves that roll around the planet as the ocean is “pulled” back and forth by the gravitational pull of the moon and the sun as these bodies interact with the Earth in their monthly and yearly orbits.

Higher than normal tides typically occur during a new or full moon and when the Moon is at its perigee, or during specific seasons around the country.” Excerpted from NOAA.
