Introduction

Reference

The top of the page will display the date with the tide station below. The top of the
chart will show 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 night (dark bar)
will 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, with the light, dotted vertical lined 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 will show 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) will indicate 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) will appear 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 top and bottom numbers to the left of the chart, ‘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.
