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) and nighttime (dark 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.
