What is a Tide Chart?
Tides are defined as the regular rise and fall of ocean water above or below mean sea level. Depending on where a person is on Earth, and the position of the Earth, moon, and sun relative to each other, tides will vary. For this reason, most parts of the world publish tide charts, in the form of a small table which outlines the expected times for high and low tide through the day. Usually, a tide chart includes the estimated height of each tide, along with the times of sunrise and sunset, along with moonrise and moonset. By using the data in a tide chart, people who work with the ocean can have safer and more productive days. A proper tide chart is a vital navigational aid, especially when maneuvering large ships close to shore or into harbor. A miscalculation in the tides could result in a catastrophic accident such as a collision with a bridge or running aground. Sailors making day trips, such as fishermen who go out every day, have tide charts relevant to their local area to assist
