This is a typical currents station. The graph shows the two days' of currents. Values above zero are flooding currents, values below are ebbing currents. If you scroll down the table, then sun and moon times are listed (we couldn't show them here).

This view is crammed with data. You can see the direction of the current, the depth of the station, the times when the next flood or ebb is occurring, the time of the slack, the times of astronomical events, and more!

Remember the rule! Red, right, returning, in the direction of the flood.
