What is a
Tide Clock: |
Tide Clocks tell the tide. It shows you how many hours there are until Low or High tide. It has a quartz movement that is set to the time it takes the moon to rotate around the earth.
The moon is the major cause of the tides. The lunar day, the time it takes for the moon to reappear at the same place in the sky, is 24 hours and 50 minutes. Most locations in Australia and around the world have 2 high tides and 2 low tides each lunar day.
These Tide Clocks rotate approx. once every 12 hours and 25 minutes, twice each lunar day. Once set correctly, the Tide Clock will always stay in exact step with the moon.................. |
Setting
Tide Clock: |
.................The best time to set your tide clock is at high tide on the highest tide of the month. This usually occurs around a full moon or a new moon. Please see your local tide charts, or go to:
http://tides.willyweather.com.au/ for this information, or purchase a tide chart.
The purpose of setting your tide clock at this time is to reduce the fluctuations that can occur due to other small factors that are not incorporated into the clock, but can also affect the tides. These are such things as the gravitational pull of the sun, atmospheric pressure, wind, and the contour of the sea bed..
It is also important to remember that high and low tide are states that exist over a period of time, not just for one minute of the day, as you may find your tide clock will fluctuate around the actual tide times. |
