Hawaii
The tide at Honolulu
A small, gentle tide by mainland standards — but on a reef coast a foot of water is the difference between paddling out and walking on coral.

What the water does here
Honolulu runs two highs and two lows a day, near enough evenly spaced. Between low and high the water moves about 1.3 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.
