A beginners Guide to Tide Clocks
What is a tide clock?
A tide clock that shows tide times for many locations around the world. Tides are a powerful phenomenon that occurs twice a day, every day of the year.
The water at high tide will be the same height as the previous low tide and the same height as the next high tide.
The art of tide prediction
Tide prediction is an important aspect of our world and it's getting more so as we rely more and more on marine transportation.
The last thing we want to do is get a cargo ship stuck in the harbor or risk an oil spill. Hence the importance of tide clocks.
Who uses Tide Clocks
Tides are water movements caused by the gravitational pull of the sun and moon, but they also affect the earth's rotation.
These gravitational effects are measurable using tide gauges installed throughout harbors around the world, which are used for things like predicting tide levels, knowing when to harvest crops, calculating wave heights for beach safety, detecting tsunamis, detecting river or wetland erosion, dredging ports, determining shipping schedules, observing rising sea levels, and many more uses.
QUESTIONS ABOUT TIDE CLOCKS ; TIME AND TIDE
Can you predict when the next tide will occur?
The tide clock allows you to view the times of day when high tides occur. The tide clock uses a color-coded chart at your location for up to eight days into the future.
It can be mounted on any flat surface, indoors or outside, and provides accurate tidal information within 1/2 foot either way
Do tide clocks really work everywhere ?
They are very easy to use. Just set it next to you wherever you are, turn it on, and the tide times are displayed right on your clock.
Most tide clocks available on the market show tide times for large seas, even if this clock never was intended to work in most oceans and seas.
The best place for tide clocks
In fact , it works best in seas or oceans with a significant tidal range, such as the North Sea.
No matter where you are, whatever the tides of your favorite beach, the tide cycle clock shows you at a glance tide information.
Are tide clocks really effective?
Yes ! Generally you can easily adjust to your location. It allows you to find out the exact time of high and low tides for a given day.
Where do tide clocks work?
Tide clocks are set, or adjusted, for your local area to ensure reliable tide information.
Tide clocks are best used in areas of the world where there is a semidiurnal tidal pattern, which occurs near coastlines closest to the equator.
Tide clocks are a handy tool to track tide cycle changes in conjunction with a nautical chart. They feature a large easy-to-read dial which enables you to keep track of the time from your local high and low tides.
Tide clock displays
The tide clock displays times in 12 hour format, from high to low, so additional time must be added when calculating the amount of water that will be covering a particular spot on the chart.
When should I set my tide clock?
The tide indicator hand on your clock should be moved at high tide. Due to the change in daily tides, the times you set it to rise and fall will vary according to your location.
Do you need Batteries for a tide clock?
Most tide clock brand has different style and its battery operated. It usually requires one or two aa battery.
What are tides anyway?
Tides result from the gravitational pull of the moon and the sun on the rotating Earth.
They are an integral part of a larger system of movements termed the water cycle, through which water is transferred from one body to another on, above, and below Earth.
At its simplest, a tide is the rise and fall of the sea level due to gravitational forces exerted on our oceans by the moon and sun. The moon is the major influence on the world's tides.
The sun's gravity
The sun's gravity also influences tides, but not as much.
Sun and moon act in concert to produce two high and low tides every 24 hours, are predictable, though close inspection will reveal that they always follow a pattern.
What time of year are tides the highest?
The highest tides of the year are at the new and full moons.
These are called spring tides, since they tend to come in the spring months, right after the winter solstice.
High tides are actually lowest at the summer solstice. This is because of how the gravitational pull of the Sun and Moon work on Earth.
The Sun pulls more strongly on the side of Earth facing it, while the Moon pulls on Earth more evenly all around its surface.
What time of day does high tide occur?
This tide occurs every 12 hours and 25 minutes, or approximately 2 hours after the Moon has reached maximum height in the sky.
During the time of day with the highest tide, it is called noon tide, and during the time with the second highest tide it is called mid-tide.
The times for exact high and low tide vary according to whether that geographic location is in the Northern or Southern Hemisphere (due to the arrangement of the land masses distributed on the Earth’s surface), and whether they are in an intertidal zone (where tidal waters cover part of their land area).
These are so important to the oceans' ecosystem.
Where does the water go?
Where do you think all that extra water goes when it leaves the beach?
While the water molecules at the beach move away from the shore a short distance, they're replaced by new molecules from further out in the ocean.
This process happens with all of the water in the sea, so it's difficult to tell whether a certain molecule is from a nearby river or an ocean hundreds of kilometers away.
TYPES OF TIME AND TIDE CLOCKS
Now you can display the time and tide right in your home or boat with these modern nautical inspired clocks. These attractive wooden clocks feature large, easy to read faces with brass finished hands.
The top section of this time and tide clock displays the current time while the bottom section shows lunar phase (new moon, half moon, full moon) time of day (AM or PM), current tide level (high or low) and tide prediction for next day.
This clock with its large display allows you to easily read out the exact time remaining before low tide and hi tide.
This large tide clock is for people with a good taste and an eye for design: it is not only useful but also stylish and is a great addition to any house.
This large tide clock will tell you the time remaining until low tide or hi tide.
There are different types of tide clocks, from traditional, watch type, solar-powered, down to different dial face, here are a few:
The Wall Tide Clock is a large wall facing tide clock, sometimes referred to as a tidal dial.
It displays the time from the tides at your location and has a descriptive metal plaque.
The Wall Tide Clock is a decorative clock that is ideal for any beach home or office.
Wall Tide Clocks make it easy to know the time and tides. All you need to do is look at your Wall Tide Clock.

Maximum Instruments Marconi Weather Station
The Merlin, Rainwatch, and Cronus clock are the most popular of our weather instruments. You can get them all in one package.
The Merlin is an analog weather station that records wind speed, wind direction, rainfall, barometric pressure, and temperature.
The large mahogany panel displays readings for wind speed, wind direction, rainfall, barometric pressure with change over time, outside temperature with high and low memory, and tide level with high and low memory.
The Merlin clocks also gives you full control of two additional displays. You can set it to display either the average wind speed or the highest gust during the current hour.
You can also set it up the display of this clocks to display either the predicted high or low temperatures for the next day.
Chrome-plated brass dials
The clocks large chrome-plated brass dials are easy to read from a distance. And if you need more detail about what's happening right now,
- There are digital readouts for wind speed,
- Wind direction,
- Barometric pressure,
- Wind chill (with low memory),
- High temperature (with high memory),
- Low temperature (with low memory),
- Rate of change of temperature (with high and low memory),
- Predicted temperature change (for tomorrow).
