tidal charts
Tidal charts are graphical tools that display the timing and height of tides at specific locations over a given period, usually a month. Tides are caused by the gravitational pull of the moon and sun on Earth's oceans, resulting in regular rises and falls of sea levels. Tidal charts help fishermen, boaters, and coastal planners understand when high and low tides will occur, informing activities such as fishing, navigation, and beach access. Each chart typically shows a timeline with markings indicating the predicted tide levels, allowing users to anticipate changes in water levels effectively.
