How to understand the tidal current graph
• Vertical axis: Speed, Horizontal axis: Time
• The information is mostly accurate under moderate weather conditions. However,
storms and weather fronts can influence forecasted tidal current directions and
speeds.
• Drag the time scale at the bottom of the screen sideways then read the tidal current
speed at the selected time (drag to the left to display the future information, right for
the past information).
• To set the time scale to the current time, select the clock mark at the bottom left-
hand corner of the screen. The color of the clock mark turns gold.
