Tide Tab—
shows a graphical chart that displays tide station information in a 24-hour span starting at
midnight station time. You can choose from different dates and over 3000 tide stations around the USA
coastline, Alaska, Hawaii, western Canada, and several of the Caribbean islands.
The top of the page displays the tide station being referenced, with the date below. The top of the chart
shows a 24-hour block of local time (LCL) for your position, with the reported station time (STA) appear-
ing at the bottom. Daylight (light or yellow bar) and nighttime (dark or blue bar) show across the time
scale, with the time progressing from left to right. (Local time scales and sunrise/sunset info may not be
available for a few 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 current time box at the top) indicates
the time of day when using current date and intersects the tide graph to show their relation.
The tide curve shows as a shaded area, with higher tides (blue) being taller and lower tides shorter. The
solid, horizontal line (with the current tide box on the left) indicates the current tide height. The figure to
the left of the line shows the current tide level in the depth units specified on the Units tab. The MLLW
appears as a solid, horizontal line near the bottom of the chart (This line only appears if the tide ranges to
the zero value or below). Tides curves below MLLW appear in red on color models. The numbers directly
below/above ‘LCL’ and ‘STA’ indicate the maximum/minimum levels, respectively. The 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.
