A King Tide is an astronomically high tide. A King Tide is a natural, predictable occurrence that happens a few times a year. This provides the opportunity to envision what our coastal areas may experience as sea levels continue to rise. These extra-high tides can help us spot areas that could be most vulnerable to sea level rise. King Tides are also known as perigean spring tides.
Casco Bay will experience a King Tide on Wednesday, February 20th, at 11:18 AM., which is estimated to reach 11.6 feet. A normal high tide in the Bay ranges from 8 to 10 feet.
We are mobilizing our volunteer Water Reporters to help us document the February King Tide to help our us visualize what sea level rise may mean for our region. Between 10:48 and 11:48 on February 20, our volunteers will don their rainboots and pull out their smartphones to capture this extreme tide using the Water Reporter app.
Water Reporter is an easy-to-use “Instagram-like” tool that enables our volunteers to document, catalogue, organize, and share observations of the Bay. This information is aiding our collaborations with other scientists, expand our community engagement by sharing observations on social media, and helping with our advocacy, to illustrate changes happening around the Bay to regulators, legislators, and other policy makers.
