Tide clocks

Our tide clocks, developed on request over the past year,  are 100% accurate no matter where you live. And they are beautiful!

Most tide clocks guess.

They rely on basic lunar cycles, which can be off by 30–90 minutes thanks to wind, pressure, and tricky coastal geography.

Our tide clocks don’t guess. They connect to NOAA—the official U.S. tide authority—and show the real high and low times for your exact beach, updated daily.

The display shows your whole day at a glance. High and low tides appear as bars (blue for high, green for low) along an LED strip, gently rising and falling in brightness, with the peak marking the exact moment of each tide. A small pulsing dot shows the current time.

At night, the display dims automatically so you can still see it without lighting up the room.  (Full user guide here.)
