High and low water
Tide charts by town
A tide chart is the predicted high and the predicted low at one station, in local time at that station. The high is the top of the rise. The low is the bottom of the fall. The height is the level of the water, not the depth under the boat.
In the United States the heights are feet above mean lower low water. In Australia and New Zealand they are metres above chart datum. A guide explains what nautical twilight means, and another explains what last light means.
Each town chart includes printable tide tables for the coming months.
Blue circles on the map are tide stations: a prediction of the rise and fall. Orange squares are flood gauges: a measurement of the water that is there. 4,201 tide charts, 152 coastal flood gauges.
