In 2020 NOAA ceased publication of the printed Tide Tables in 2020. Another watershed in the move toward a totally digital world of navigational information. Working the Tide Tables was once an important part of any coastal navigation course (even if actually using the Tide Tables was less widely used in practice!). The agency’s tide info isn’t going away, however. It is still available in digital form. It’s all laid out in this recent NOAA press release:

“All NOAA tide and tidal current predictions for locations around the nation are available in electronic form online. NOAA eliminated paper publications of the annual Tide Tables and Tidal Current Tables in 2020.

“The change from print to online tables allows us to modernize this long-standing product by bringing it into the digital age. Online predictions are more accurate and up-to-date than what is provided in the annual printed tables. NOAA tide predictions are used by both commercial and recreational mariners for safe navigation. NOAA’s Center for Operational Oceanographic Products and Services produce these tide tables on an annual basis.

“Member nations of the International Hydrographic Organization make their annual tide and tidal current predictions publically available. This allows each member country to produce annual predictions for locations around the world, in their native language, for use by mariners, shipping industry, and recreational users. NOAA’s annual tide and tidal current tables include predictions for more than 10,000 international locations.

“You can get tide predictions and tidal current predictions online for U.S. coastal stations and some islands in the Pacific and Caribbean, for a time period of up to two years.”
