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 dark, vertical line (with arrows at the ends of the line) 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 

dark, horizontal line (with arrows at the ends of the line) 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, vertical 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.
