This high tide is royalty! Here’s your chance to see the king….tide that is. Join us for a hike to learn about extreme high tides, known as king tides, which are happening more often due to environmental change. These extreme tides have a variety of impacts on coastal infrastructure, including restricted access on low lying roads, flooded buildings, and impacts of erosion, debris, and salt-water intrusion/damage. The king tide also provides us with a window to the future, illustrating what an average high tide might look like in a few decades due to sea level rise. On this hike you will learn what causes king tides, see the tidal impacts first-hand, and learn what The Trustees are doing to increase the coastal resilience of our treasured coastal environments.
