Tide Data
The symbol indicates tide height data is available for that position on the
chart. When you select the tide height option, a graph of predictions for
maximum and minimum tide heights is displayed, data for sunrise and sunset is
also provided as illustrated below.
Note: The predictions available are sufficiently accurate under moderate
weather conditions, for the coastal areas served by the reference station, to be
used for navigation planning. However, certain weather fronts and storms can
alter tidal patterns and influence predicted times and heights.
