Tide Tab

Use the Tide tab to view tide and current information. The Tide tab contains two

sub tabs: Tide and Current.

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 and the date. The bottom of the Tide sub tab shows the

distance and bearing from your location.
The bottom of the Tide chart shows a 24-hour block of local time for your

location. Daylight (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.

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). The numbers on

the top and bottom of the left side indicate the maximum and minimum levels.

The four data fields below the chart indicate event times and levels at which the

tide changes, starting in the upper-left field, going downward, then to the upper-

right, and down again. When comparing with other tide tables, verify that the

depth unit’s value is the same for both sources. The bottom of the chart shows the

amount of time (in hours and minutes) until the next low tide and high tide.
