How does a tide clock work?
Tides are caused by many factors, but by far the most influential is the moon's gravitational pull on the ocean. It takes the moon on average 24hrs, 50 minutes and 28 seconds to reappear at the same place in the sky, during this period most areas in the world have two high tides and two low tides.
The tide clock has been specially designed to rotate twice each period giving you a quick and easy indication of high and low water.
There are other influences on sea levels that affect exact tide times and the user should take these into account:
-Strong onshore and offshore winds-Changes in the volume of river flows-variations in atmospheric pressure-The sun's own gravitational pull, when lined up with the moon increases the tidal range, and can alter tide times by up to an hour.
Full instructions on how to set up your tide clock are included.
Diameter: 5x22cm
Please note that we do not recommend situating the clock in an area which receives prolonged exposure to strong, direct sunlight
