Answer:
Technically, there is no such thing at what tides are the highest because they are formed by water in the ocean/sea and we have no names to them because they are not an organism and they are an abiotic factor. Though, I believe the highest tide(s) in the world are in Canada. As big/high tides are usually nicknamed or called: "King Tide", "Solar Tides", "Spring Tides", etc. to decribe the highest tides.
Explanation:
Tides are created by the gravitational forces on Earth by the Moon and the Sun, together. Hope this helps! I tried my best to help you out :)
