Tide Sub Tab
The Tide sub tab contains a graphical chart that shows Tide Station
information in a 24-hour span starting at midnight. You can choose
from different dates and more than 3,000 Tide Stations around the
U.S.A. coastline, Alaska, Hawaii, western Canada, and several of
the Caribbean islands. The top of the Tide sub tab shows the Tide
Station, the date, and the distance and bearing to the Tide Station
from your location.
The bottom of the Tide chart shows a 24-hour block of local time
for your location. Daytime (yellow bar) and nighttime (blue bar)
at the Tide Station are shown across the time scale, with the time
progressing from left to right (sunrise and sunset information might
not be available for some Tide Stations). The solid, light vertical
lines are in 4-hour increments, and the light, dotted vertical lines
are in 1-hour increments. A solid, vertical line (with the local
time at the top) indicates the tide height corresponding to the time
shown in the local time box.

Low tide curve
The Tide curve is shown as a shaded area, where higher tides are
taller (blue) and lower tides are shorter (red). The solid, horizontal
line indicates the tide height. The figure to the left of the line shows
the present tide level. The Mean Lower Low Water (MLLW)
appears as a solid, horizontal line near the bottom of the chart
(this line appears only if the tide height range is zero or below).
