HIGH TIDE - LOW TIDE

 So first let's talk about tides.

Tides are the rise and fall of sea levels due to the gravitational pull of the moon and the sun on the earth.

The moon has a stronger effect than the sun because it's closer to us. When the moon is directly above or below a point on the earth, it creates a high tide there.

When it's at a right angle to that point, it creates a low tide there.

This happens twice a day, every day.

As we know, earth is not a perfect sphere, and neither is the moon. They have bulges and bumps that affect how they pull on each other.

Also, the earth rotates faster than the moon orbits, so the high and low tides shift slightly every day.

And then there's the sun, which also pulls on the earth, but in different ways depending on its position and the seasons.

Sometimes the sun and the moon work together to create extra high or low tides, called spring tides.

Other times they work against each other to create less extreme tides, called neap tides.

So you see, tides are not just a simple cycle of high and low. They are influenced by many factors that vary from place to place and time to time.

That's why you need a tide table to know when and how high or low the tide will be at a specific location.

But let's get back to your question.

If it's high tide where you are, will it be low tide on the other side of the world?

Well, not necessarily.

It depends on where you are and where the other side of the world is.

If you are on the same latitude as the other side of the world, then yes, it will be low tide there when it's high tide where you are.

But if you are on different latitudes, then no, it won't be low tide there when it's high tide where you are. It might be high tide there too, or somewhere in between.

Let's say you are in New York City (40°N) and it's high tide there at noon. The other side of the world from New York City is somewhere in the Indian Ocean (40°S).

It will be low tide there at noon too.

But if you are in Seattle (47°N) and it's high tide there at noon, the other side of the world from Seattle is somewhere in Antarctica (47°S).

It won't be low tide there at noon. It might be high tide there too, or somewhere in between.

Bottom line:

You can't just assume that if it's high tide where you are, it will be low tide on the other side of the world. You need to check a tide table for both locations to know for sure.
