Interpreting the Admiralty Tide Table 2013
Understanding Tide Predictions
Tide tables provide two primary pieces of information:
- Time of High and Low Waters: The predicted times when the tide reaches its maximum (high tide) and minimum (low tide) levels.
- Tidal Heights: The expected water level relative to a fixed datum, often in meters or feet.
Reading the Data
- Date and Time: Each entry is associated with a specific date and time, often in Coordinated Universal Time (UTC).
- Tide Heights: Usually given as a height relative to a chart datum, indicating the depth of water at that specific time.
- Tide Graphs: Many tide tables include graphical representations to visualize the rise and fall of tides over the day.
Key Concepts in Tide Prediction
- Mean High Water Spring (MHWS) and Mean Low Water Spring (MLWS): Indicators of average high and low tides during spring tide periods.
- Neap Tides: Periods when the difference between high and low tides is minimal.
- Tide Cycle: The regular pattern of tides caused by the gravitational pull of the moon and sun, which the tables aim to predict accurately.
Significance of the Admiralty Tide Table 2013
