Understanding the ebb and flow of the Atlantic Ocean against the rugged shores of Portland not only enhances your visit but also connects you deeply with the rhythm of the natural world. Let's dive into the world of tide tables and discover how they can reveal the secrets of the Maine coastline. π

Maine's coastline, with its over 3,478 miles of craggy shores, islands, and tidal inlets, experiences some of the highest tides in the United States. This means that the difference between high and low tide can be as dramatic as 12 feet in some areas, like in the Bay of Fundy. Here's what makes tides in Portland so special:
-
Dynamic and Predictable: Tides are influenced by the gravitational forces exerted by the Moon, the Sun, and the Earth's rotation. While tides are predictable, their influence on Maine's waters is dynamic, offering a changing landscape daily.
-
Dual High Tides: Unlike many other coastal regions where tides come in and out once every day, Portland experiences two high tides and two low tides in roughly 24 hours, due to the declination of the Moon.
-
Ecological Impact: Tides bring in nutrients, which sustain rich marine life, making Portland a haven for seafood lovers and a vital part of the local economy.
Deciphering Tide Tables π§

Tide tables, often published by various government agencies or local marinas, are essential tools for anyone interacting with the sea. Here's how they work:
-
Tide Heights: The tables provide the height of the tide above or below the mean lower low water (MLLW), which is the average height of the lowest tide recorded each day over a specific period.
-
Times: Each tide table entry includes the times for high and low tides, allowing you to plan your day around these events.
-
Interpreting Graphs: Modern tide tables might come with graphs illustrating the tidal cycles, making it easier to visualize when tides will peak or ebb.
