Aren't There Really Big Waves in Tahiti?

Tides come from gravitational pull of the moon and sun. If we did not have tides, then you wouldn't get a difference in ocean level. The tide ranges maximumly from about 12 meters to 15 metres. In six hours it goes up and down by two meters an hour. And at the other place in the world, you have tahiti, which has no tides.
