Current Sub Tab
The Current sub tab shows information for currents in a 24-hour span, starting
at midnight. You can choose from different dates and more than 3,000 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 For 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.
3. Select a Current Station from the list, and press ENTER. As you move
the highlight over each Current Station in the list, the station is highlighted
on the map window. The distance and bearing from your location to the
highlighted station are shown at the bottom of the list.
