Programs Mapping and Charting Support. CO-OPS’ Mapping and Charting Services Program is based on NWLON and its primary purpose to accurately collect water level data to meet NOAA’s mission and goal requirements for water level information.
Tides & Currents Education. What are Tides? - Tides are one of the most reliable phenomena in the world. As the sun rises in the east and the stars come out at night, ocean waters regularly rise and fall along our shores. Read more about "What are Tides?"

Nowcast and forecast (out to 48-72 hours) model information on water levels, currents, wind, salinity, and water temperature.
What are Tides? Tides are the ‘heartbeat’ of our ocean. Much like the sun rises each morning, tides occur predictably around the world. Beaches and treacherous reefs are often visible for enjoyment or avoidance (respectively!), but other times are obscured under many feet of ocean water.
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.
JTides is an advanced, accurate, easy-to-use tide and current prediction program. JTides predicts tides and currents using a large database of US and worldwide locations. It graphs its predictions in many useful ways.
