It has NOTHING AT ALL TO DO WITH WHICH SIDE OF THE EQUATOR YOU ARE
It depends on how the water is moving when they plug is pulled, the shape of the sink/bath that it is running out of, and how the plug is removed.
You can make water spin either way by changing these things EITHER SIDE OF THE EQUATOR

The effect is named after a man named Corliosis. He reasoned that the farther you get from the poles, the greater the surface speed of the earth. At either pole it's zero and at the equator it's 25,000 miles per hour, therefore any stationary fluid has one side closer to the equator and the other is closer to the pole. As the earth turns the side of the sample that's closer to the equator is moving relatively slower so it will be left behind, the force that makes the fluid rotate. You will see the same thing if you are on a high bridge on a calm day and drop a stone. It won't go straight down? It will appear to curve to the east. It only appeared to curve but really did go straight down from where you released it, while you traveled farther west. The same effect happens when you look at a weather map. You will notice the air (a fluid) goes clockwise around the high pressure areas because the air at the highs center is rising as more air is coming in towards the center displacing other air up. So the southern edge (in northern hemisphere) of that high parcel is closer to the equator. The effect is clockwise rotation of the highs and because the air is going down in low pressure parcels the rotation is counter clockwise. By the way, at the equator the water in a bowl goes straight down I know, I've done it. Now you tell me why that is so. Bud

It is supposed to go clockwise north of the equator, and counter clockwise south of the equator. It has something to do with the magnetic poles.

Depends on if you live north or south of the equator

It's counterclockwise.
