    Been trying to learn about the tides around here so I can tell what I’m seeing on the water. Imagine my joy when I found a Casio, which I collect, with tide and moon phase indicators!

    And that’s when I learned the Gulf Coast is strange, has diurnal tides (twice a day) the watch can’t predict. Took me an hour and a half to figure out it would never function. The moon phase works!

      Diurnal tides are once a day (semidiurnal is twice a day). By the Gulf Coast, I guess you must mean the Gulf of Mexico. I’m living on the other side of the world in the other diurnal region, so I assume our tides are synchronised!
