Mobile Bay Tide Table

The Mobile Bay, located in the Gulf of Mexico, is a vital estuary with a rich ecosystem that supports a wide variety of marine life. One of the key factors that influence the bay's ecosystem is the tide, which is the periodic rising and falling of the sea level caused by the gravitational pull of the moon and the sun. Understanding the Mobile Bay tide table is essential for various activities such as fishing, boating, and coastal engineering. In this article, we will delve into the details of the Mobile Bay tide table, its importance, and how it affects the local ecosystem.

- The bay's ecosystem is affected by the tide, with varying water levels impacting marine life and coastal erosion.
- Understanding the tide table is crucial for predicting tidal currents, water levels, and wave patterns.
- The National Oceanic and Atmospheric Administration (NOAA) provides accurate and reliable tide predictions for the Mobile Bay.
Understanding the Mobile Bay Tide Table

The Mobile Bay tide table is a complex system that is influenced by various factors, including the moon’s gravitational pull, the sun’s gravitational pull, and the shape of the bay. The tide table is typically divided into two main categories: high tide and low tide. High tide occurs when the water level is at its highest point, while low tide occurs when the water level is at its lowest point. The difference between high and low tide is known as the tidal range.
The tidal range in the Mobile Bay is relatively small, with an average range of around 1.5 feet. However, the tidal range can vary significantly depending on the time of year, with the highest tidal ranges occurring during the spring and fall equinoxes. The tide table is also influenced by the wind, which can cause the water level to rise or fall, and by the shape of the bay, which can affect the tidal currents.
Tidal Cycles and Patterns
The Mobile Bay tide table follows a predictable pattern, with two high tides and two low tides occurring every 24 hours. The tidal cycle is influenced by the moon’s gravitational pull, which causes the water level to rise and fall in a periodic manner. The tidal cycle is also influenced by the sun’s gravitational pull, which has a smaller effect on the tide than the moon’s pull. However, when the sun and moon are aligned, their gravitational pulls work together to create an even higher high tide and an even lower low tide, known as a spring tide.
The tidal patterns in the Mobile Bay are also influenced by the shape of the bay and the surrounding coastline. The bay’s narrow entrance and shallow waters cause the tidal currents to be stronger and more turbulent than in other areas. This can lead to a phenomenon known as a “ tidal bore,” where the incoming tide creates a wave that travels up the bay, causing the water level to rise rapidly.
Tidal Component | Amplitude (feet) |
---|---|
M2 (Principal Lunar) | 0.83 |
S2 (Principal Solar) | 0.23 |
N2 (Lunar Elliptical) | 0.14 |
K2 (Lunisolar) | 0.08 |

Importance of the Mobile Bay Tide Table

The Mobile Bay tide table is essential for various activities, including fishing, boating, and coastal engineering. Fishermen and boaters need to understand the tide table to navigate the bay safely and to avoid getting stranded in shallow waters. Coastal engineers need to understand the tide table to design and build structures that can withstand the forces of the tide and to predict the impact of tidal currents on coastal erosion.
The tide table is also important for predicting tidal currents, water levels, and wave patterns. Tidal currents can be strong in the Mobile Bay, particularly during the spring and fall equinoxes, and can pose a hazard to boaters and swimmers. Understanding the tide table can help predict when and where these strong currents will occur, allowing for safer navigation and recreation.
NOAA Tide Predictions
The National Oceanic and Atmospheric Administration (NOAA) provides accurate and reliable tide predictions for the Mobile Bay. NOAA uses a complex system of tidal gauges and computer models to predict the tide table, taking into account various factors such as the moon’s gravitational pull, the sun’s gravitational pull, and the shape of the bay. The predictions are available online and can be accessed by the public, providing essential information for fishermen, boaters, and coastal engineers.
