Tide tables are typically organized by geographic region or country and provide information for a particular time period, usually a month or a year. They list the predicted times of high and low tides for each day, along with the corresponding tide heights.
The main components of a tide table include:
1. Location: The name and geographic coordinates of the specific location for which the tide information is provided.
2. Date and Time: The table displays the dates and times for the predicted tides. The times are usually listed in either local time or Coordinated Universal Time (UTC).
3. High Tide: The times and heights of the high tides are listed for each day. The heights are typically measured in meters or feet above a specified reference level, such as mean sea level (MSL).
4. Low Tide: Similarly, the times and heights of the low tides are listed for each day.
5. Tide Differences: Some tide tables also include information on the differences between the predicted high and low tide heights. This provides an indication of the range of the tide over a specific period.
Tide tables are created using various methods, including astronomical calculations and observations. They take into account factors such as the gravitational influence of the moon and the sun, as well as local geographic conditions like the shape of the coastline and underwater topography.
It's important to note that tide predictions may vary from actual tide observations due to changes in weather conditions, atmospheric pressure, and other environmental factors. Therefore, it's always advisable to consult the latest tide tables and consider local knowledge when making decisions based on tide information.
