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 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) 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 (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 fi gure to 
the left of the line will show the current tide level in the depth units specifi ed on the Units tab. The 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). Tides curves below MLLW will appear in red on color models The numbers 
directly below/above ‘LCL’ and ‘STA’ indicate the maximum/minimum levels, respectively. The 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.
