How do tides work at the North and South Poles?

Tides are only started by the moon, as you can see by tides being much smaller the more isolated a body of warer is - e.g. the Mediterranean Sea has less tides than the oceans, and the Baltic Sea even less, and lakes barely any. read more

In regard to ocean tides in particular: the South Pole is on land so there are no ocean tides; and the North Pole is frozen so it is hard to see the 0cean tides! It is true that tides tend to reduce with increasing latitude, but there are many other factors including the shape of the coastline. read more

Tides aren't observed at the poles because at the North Pole, it is all ice and (so far) doesn't melt, and at the South Pole it is snow-covered land, and land isn't observably affected by tides. You need to be somewhere where there is large amounts of liquid water for tides to be apparent. read more

Both poles are slightly different, however; the region around the North Pole—the Arctic—is simply a large sheet of ice covering ocean underneath, whereas the South Pole—the Antarctic—is actually a continent covered by ice that also extends part of the way into the surrounding water. read more
