How does it work ?
The moon is primarily responsible for the tides. The time from
one moonrise to the next is 24 hours and 48.7 minutes. This is why the time
of the next high tide keeps changing.
The sun also affects the tides, but has less than half the influence of the
moon. So when the sun, moon and earth are all lined up, as they are at times
of new moon and full moon, their gravitational influences co-incide making the
high tide, higher, and the low tide, lower. When the sun and the moon are at
right angles, during the first and last quarters of the moon, the sun cancels
some of the moon's effect and the range of tide is smaller than normal. Also,
at these times the sun's gravitational pull makes the tides come earlier or
later than usual, which is why the tide clock can be up to half an hour out.
This is why it is so IMPORTANT to first set your Tide Clock at the high tide on the day of a full moon, as the moon has the dominating effect with the tides. Have a look at our links page for more information about tides.
Will it work in my area?
Because tides all over the world rely on the cycle of the moon, it doesn't really matter where you are. The time-tide clock will work anywhere in the world as long as the tides are regular. If you are able, at present, to use a tide chart to check when the next high tide is due, then you will be able to use our tide clock. Most places have two high tides and two low tides each day. But local currents and landforms can change that. You should check your local area. If you do not have regular tides, the tide clock may not work. Known areas for this are Shark Bay in Western Australia and Portland in Victoria, where occasionally only one change of tide occurs. And some parts of the west coast of the USA
What about Daylight Saving?
The tide clock tells you how long until the next tide, not what time it will occur. Therefore it is not affected by daylight saving.
