Once set this region specific tide clock acts as a tide chart displaying the High Tide times and Tidal time differences between the major ports and waterways of Massachussetts (periodic adjustment needed).

During the 90’s, Ocean Clocks had an idea that would enhance the standard tide clock currently produced today by offering a tide clock that would display High Water at the major and minor ports of local regions. If you have checked your local tide time tables you will see that the high tide times will differ from port to port. There is a time difference from one port to another as the tide makes its way around the coastline. In some regions the tide difference between one port to another can be as much as 6 hours stretching over the length of the State or regional coast. This could be due to many factors such as local land masses, estuaries, currents and ocean basins. The calculation of these time differences will generally not change except under the influence of bad weather. Over the many years that Ocean Clocks have been developing their clocks, they have collected and plotted data from around the world. This data aids in calculating the correct time difference of the high tide related to the port angles situated on the face.

The blue tide hand on the Ocean Clocks Tide Time Clock is designed to track the moon's orbit to approximately predict the tides. The tide time differences between all of the ports have been calculated to predict the high tides before and after the major port in your region.
