Yesterday and today, we had a "King Tide," the highest tide of the year. We took a photo today, and another nine days ago — as part of a nationwide program.
At today's high tide at River Barge Park, 16 treads on the launch ramp were exposed. At the high tide 10 days ago, 27 treads were exposed.
The New York-New Jersey Harbor Estuary Program writes: "As part of an effort across the country to raise awareness about sea level rise, the Harbor Estuary will be coordinating photo documentation of the King Tide.
"The King Tide is not caused by sea level rise, but gives us an idea of what average high tide levels are likely to be in 20-30 years."
