tidsposters

A tidposter is a type of poster that displays information related to tides. These posters are typically used in coastal areas, maritime facilities, and for educational purposes to inform individuals about tidal patterns. They often include data such as high tide and low tide times, tidal ranges, and sometimes information about moon phases which influence tides.

Tidposters can vary in their complexity and the specific information they provide. Simple versions might show daily tide predictions for a particular location, while more elaborate ones could cover seasonal variations or provide detailed explanations of the factors that cause tides. The visual design of tidposters is also diverse, ranging from functional charts and graphs to more illustrative displays. They are a practical tool for fishermen, boaters, surfers, and anyone who needs to be aware of the changing water levels at the coast. Educational institutions may use tidposters to teach about oceanography and celestial mechanics. The term itself, "tidposter," is a portmanteau combining "tide" and "poster," directly describing its function.
