The Moon is at the origin of tides on Earth. Every lunar day, our planet rotates through two tidal bulges. In coastal areas, two high tides and two low tides happen within 24 hours and 50 minutes. This delay alternating between a high tide and a low tide represents a tide cycle. Stay connected to the ocean from home with your tide clock. Know when is the right time to go to the beach and don't forget your surfboard!
