Tide Tables

Charts or listings that provide the predicted times and heights of high and low tides for specific coastal locations over a given period.

Tide tables are essential tools for mariners, fishermen, and anyone involved in coastal activities, as they offer crucial information about the timing and magnitude of tidal changes. These tables are typically presented in a calendar format, showing the expected times for high and low tides and the corresponding tidal heights. The data is usually provided for specific locations, as tides can vary significantly depending on geographic features, such as bays, estuaries, or the open sea. Tide tables are based on astronomical calculations that consider the gravitational pull of the moon and the sun and the Earth’s rotation. However, local factors such as wind, atmospheric pressure, and ocean currents can influence actual tidal conditions, so real-time observations are sometimes necessary to complement the predictions.

Tide tables are indispensable for safe navigation. They help mariners avoid grounding in shallow waters and plan their routes through tidal channels. They are also crucial for activities like docking, launching boats, and crossing tidal bars. Moreover, they are used in environmental and scientific studies, such as monitoring coastal erosion or planning marine conservation efforts. While traditional tide tables were printed in booklets, digital versions are now widely available, often integrated into marine navigation systems or accessible via mobile apps.
