Main Menu: Tide Tab

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, below that the date. The top of

the chart shows a 24-hour block of local time (LCL) for your position, with the reported station time

(STA) appearing at the bottom. Daylight (light/yellow bar) and nighttime (dark/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) will indicate the time of day when using current date and will intersect the tide graph to show

their relation.

The tide curve shows as a shaded area, with higher tides being taller and lower tides shorter. The

solid, horizontal line (with the current tide box on the left) indicates the current tide height. The ﬁ gure

to the left of the line will show the current tide level in feet. The Mean Lower Low Water (MLLW)

appears as a solid, horizontal line near the bottom of the chart (This line will only appear if the tide

ranges to the zero value or below). The numbers directly below/above ‘LCL’ and ‘STA’ indicate the

maximum/minimum levels, respectively. The four data ﬁ elds below the chart, indicate event times and

levels at which the tide changes starting in the upper left ﬁ eld, going downward, then to the upper

right and down again.
