If you're at the same Shore every day, why is high tide always at a different time? Because a tidal day is more than 24 hours, the moon controls the tides. With its gravitational pull it creates high tide when it's far and close to us and low tide in the times in between, while a day on Earth is 24 hours, based on the sun. A day based on the moon is 24 hours and 50 minutes. That's because the moon revolves around the Earth, while Earth also spins in the same direction. For the same spots on the Earth and moon to line up, the moon would need to do a little more work, so a tidal day is a little more than 24 hours, meaning the tides are a little behind every day.
