The highest tides occur when the Moon is new or full. High tides sometimes occur either before or after the Moon is straight overhead. Twice a month, the difference between high tide and low tide is at its smallest. These tides are called neap tides.

Where are tides the highest?

The highest tides in the world can be found in Canada at the Bay of Fundy, which separates New Brunswick from Nova Scotia. The highest tides in the United States can be found near Anchorage, Alaska, with tidal ranges up to 40 feet .

Are tides higher at night?

It does not rise only at night. Actually the moon is in the sky during the day just as long as it is in the sky during the night, it's only that it's very difficult to see it during the day because the Sun is too bright in comparison. And thus, tidal waves rise as much during the night as they do during the day.
