Daily, weekly or yearly predictions can be downloaded in text, CSV, XML and PDF formats. Users also have the option to highlight currents above or below a given speed threshold to provide approximate time periods of maximum or slack current, which is useful for boaters and divers alike.

Tides.If you live near the coast or have ever visited the beach, you are probably aware of tides. But did you know that tides are really big waves that move through the ocean in response to the forces exerted by the Moon and the Sun? Tides start in the ocean and move towards the coast, where they appear as the regular rise and fall of the sea surfa...
We need accurate tide and current data to aid in navigation, but these measurements also play an important role in keeping people and the environment safe. A change in water level (due to tides) can leave someone stranded (or flooded). And knowing how fast water is moving—and in what direction—is important for anyone involved in water-related activ...
NOS has been measuring and predicting tides since the early 1800s. We've come a long way since the days of sticking a rod into the water to determine water level. Today, we use engineered air acoustic and pressure systems to automatically detect and record changes in water levels. All data are recorded electronically, transmitted via satellite ever...
The two main components of currents are speed and direction. To measure a current, toss an object into the water and time how long it takes to get to a certain point a known distance away. Granted, technology allows us to be a little more accurate and sophisticated in our measurements. For example, the object in the water might be a buoy that is eq...
Want to know the high and low tides for locations around the United States? Visit the Center for Operational Oceanographic Products and Services Web site. You'll find tidal predictions for more than 3,000 water-level stations around the United States. Some of the stations (called "reference stations") include full daily predictions while others (ca...
If the level of water is constantly changing, how do we know how much water levels have risen or fallen from "normal?" To define "normal," scientists use a reference, or datum, as a starting point from which all measurements are made. The numbers that appear on a nautical chart represent water depths measured relative to such a datum. Mean lower lo...
When a ship passes under a bridge, it is best if the ship doesn't hit the bridge…right? Might sound like a no brainer, but ships are getting bigger, and the space underneath bridges is staying the same, making for a potentially tight squeeze. Knowing how much space is available under a bridge requires knowing what level the water is at any given ti...
What's going on in a busy port is much like what's going on at a busy airport. Just as aircraft flying in and around an airport need current weather and ground conditions, ships coming into port need to know exactly what's going on in the water and in the air in real time. Enter the Physical Oceanographic Real-Time System, or PORTS®. PORTS provides...
Climate change has certainly generated a lot of buzz. A shift in climate doesn't just mean changes to air temperatures or weather patterns…it could also impact the ocean. A warmer climate could mean higher sea levels, from both melting sea ice and expansion of seawater. The Center for Operational Oceanographic Products and Services maintains a reco...
When someone is lost at sea, time is of the essence. Knowing the speed and direction of currents can help the U.S. Coast Guard conduct search and rescue operations with greater accuracy. The Integrated Ocean Observing System uses high frequency radar systems to develop maps of surface currents for the Coast Guard to use in their operations. These m...
Tide Predictions. Generate a graphical display or a tabular listing of daily high and low tide predictions for more than 3,000 locations around the nation. Predictions may be generated up to two years in advance. Real-Time Tide Data. Access current water levels from approximately 200 active water level stations. Historic Tide Data. For a given ...
NOAA produces predictions for tides and tidal currents, both of which are useful for navigating U.S. coastal waters. NOAA (NOS) Tide Predictions Tide predictions are a calculation of what the water level will be based on tidal harmonic constituents - driven by lunar cycles.
