There is great variability with depth to the point that some current tables will give data for current speeds at depths below the surface. This is very similar to the wave created by sloshing water in a bathtub. [See example here (jpg)] The exact relationship between the times of high and low tides and the maximum current or slack water is unique to each location and cannot be determined from a generic "rule of thumb". When survey leveled from these markers to the tide station, the relationship calculations for these marks must match within 9 millimeters. Simply navigate to the station you would like predictions for and click Annual Prediction Tables at the top of the page (see figure 3). NOAA 2020 tide tables are now available.

Current Charts refer to a series of maps that show the currents speed and direction throughout a bay or estuary at a particular point in time. "Current Tables" refer to tidal current predictions tables, which provide a listing of the times and speeds of the daily flood, ebb, and slack currents, or hourly interval currents speeds, for a particular location. If high winds are steady for a long period (e.g. The current then begins to slow again, heading toward the next slack, and this deceleration also takes about three hours. Slack water occurs when the incoming current due to the tide change cancells the outgoing current coming from the rivers and streams.

When the tide is about to reach its highest or lowest point and the tidal current ceases we call it slack water or slack tide.
