Tide Tab
Tide Tab— shows a graphical chart which 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 bar or yellow on 182C) and nighttime (dark bar or blue on
182C) 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 (blue on 182C) and lower tides
shorter (red on 182C). The solid, horizontal line (with the current tide box on the left) indicates the cur-
rent 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.
