How Time & Tide Clocks Work Tides are the rise and fall of ocean waters caused by the gravitational forces mainly between the Earth and the Moon (the Sun also generates tidal forces, but they are much smaller). These forces cause the oceans to stretch towards and away from the moon, forming two tidal bulges. The Earth rotates through these two tidal bulges causing two HIGH tides and two LOW tides every Lunar day. A Lunar day is 24 hours and 50 minutes long. This is longer than a solar day (24 hours) because the Moon revolves around the Earth in the same direction as the Earth rotates. It takes a little longer until the Moon is over the same position. Since the Moon has the greatest effect on the tides, ALL tide clocks are synchronized to the Lunar day and will indicate a HIGH tide every 12 hours and 25 minutes (two times per Lunar day). Think of it this way: A standard clock, set for your location, displays 12:00 when the Sun is directly overhead (noon), OR on the direct opposite side of the Earth (midnight). A Tide clock, set for your location, displays HIGH TIDE when the Moon is directly overhead OR on the direct opposite side of the Earth. Many factors can influence if you will experience the brightest time of day at 12:00 noon on your standard clock. Similarly, many factors can influence if you will experience the highest water of the day at HIGH TIDE on your Tide clock. One of these factors is that the large continental land masses interfere with the Westward travel of the tidal bulge and this causes many complex tidal cycles,especially on the West coast of North America. Ocean floor topography, bays and narrow inlets can cause resonance effects and even weather conditions can alter the timing of the tidal cycle. For these reasons, Tide clocks will be more accurate in some areas than others. The red outlined areas on the map are where you can expect to receive accurate tide information.

Title: Easy to set up
Review: This tide table clock makes a nice appearance. The tides are simple to read. It took only seconds to set up. The directions are clearly written. I decided to wait a while before I wrote a review. I wanted to be certain that the clock functioned well. It does and it's a great buy made of US parts in Canada

Title: Time and tide is close.
Review: Nice looking on the wall. As for accuracy it’s been running about +1 min per day. Right now it’s +3 mins. I’ll adjust it. As for the Tide II is very close and just an approx. guide.I buy it again and the price was fair.

Title: Do you need to Know the tide ?????
Review: This is a very nice clock - the only problem is that I ordered it as a TIDE CLOCK.The red hand that indicates the position of the tide (high---low) is so small that you need to be righton top of the clock to see it. The tide hand is 1 1/4 inches long. This does not reach the numbers to be able to read the (high-low) position of the tide. This is a 14" clock that has nice decoration on the face but I need to stand right next to it to read the small red tide hand. I live in an area where it is important to follow when the high tides aresince our streets flood. Driving through salt water does wonderful things to the underside of your vehicle!!!!!

Title: Does not keep time even with brand new batteries.
Review: Returned clock. Installed two sets of brand new batteries just to be sure the batteries weren’t defective. Clock would not keep proper time. Don’t waist your time and money on this.
