How a Tide Indicator Works
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.
Tide clocks can only be accurate in the red areas
