You can choose from different dates and over 3000 tide stations around the USAcoastline, Alaska, Hawaii, western Canada and several of the Caribbean islands.The top of the page displays the tide station being referenced, and the date. The bottom of thechart shows a 24-hour block of local time for your position. Daylight (light bar or yellow on 172C) andnighttime (dark bar or blue on 172C) show across the time scale, with the time progressing from left toright.

The solid, lightvertical lines are in 4-hour increments, and the light, dotted vertical lines are in 1-hour increments. Asolid, vertical line (with the current time box at the top) will indicate the time of day when using cur-rent 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 172C) and lowertides shorter (red on 172C). The solid, horizontal line (with the current tide box on the left) indicatesthe current tide height. The figure to the left of the line will show the current tide level.
