Tidal tables are essential for ports and harbours because they provide critical information about the timing and height of tides, which directly affects navigation, docking, and operations within these facilities. Accurate tidal predictions allow port operators to plan ship arrivals and departures, manage shipping schedules, and ensure safe maneuvering in and out of the harbours. Understanding tide levels is vital for avoiding grounding in shallow waters, determining when vessels can safely navigate under bridges, and synchronizing loading and unloading activities with the appropriate water heights.

While fishermen and coastal tourists may also benefit from tidal information for their activities, their needs are typically less complex than those of ports and harbours, where precise planning and safety measures are paramount. Everyday beachgoers might reference tidal information for recreational purposes, but the level of detail and accuracy required for port operations makes tidal tables absolutely indispensable for harbours.
