Alaska
The tide at Anchorage
Cook Inlet has the biggest tides in the United States. The water moves so far, and so fast, that the mud it leaves behind is genuinely dangerous.

What the water does here
Anchorage runs two highs and two lows a day, and rarely the same size twice. Between low and high the water moves about 25.5 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.
