The tide at Provincetown
At the curled tip of Cape Cod the flats run out for what looks like a mile at low water, then quietly fill in behind you.

What the water does here
Provincetown runs two highs and two lows a day, near enough evenly spaced. Between low and high the water moves about 9.7 feet, averaged across a week of predictions.
A Wavepane on the wall shows that as a picture rather than a table: the water sits where the water sits, and the wave on top grows or flattens with the swell outside. It wakes every half hour, redraws, and goes back to sleep. Nothing to open, nothing to check.
