Current Sub Tab
The Current sub tab contains graphical charts showing information
for currents in a 24-hour span starting at midnight. You can choose
from different dates and Current Stations around the U.S.A.
coastline, Alaska, Hawaii, western Canada, and several of the
Caribbean islands. The top of the Current sub tab shows the current
station, and the date. The bottom of the tab shows the distance and
bearing from your location.
The Current sub tab contains two charts—one for speed and one
for direction.
The top chart is the speed chart, which shows the speed of a given
current at any point during the day. The shaded area is blue (Flood
Current) when the current is heading toward shore; the shaded area
is red (Ebb Current) when the current is heading away from shore.
The bottom chart is the direction chart, which shows the direction
of the current at any given point during the day (based on the north
reference, not true north.)
The bottom of each chart shows a 24-hour block of local time for
your location. Day (yellow bar) and night (blue bar) at the Current
Station appear across the time scale, with the time progressing
from left to right (sunrise and sunset information may not be
available for some 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 local time at the top)
indicates the strength of the current that corresponds to the time
shown in the local time box.
To select the Current Station nearest to your location:
1. Highlight the At field, and press ENTER to open the Find
Currents Page.
2. Highlight Current Position , and press ENTER to open the
Find Near Current Position Page.
