NOAA CO-OPS

NOAA Center for Operational Oceanographic Products and Services (CO-OPS) provides REST APIs for tides and currents predictions, observed water levels, meteorological data (wind, barometric pressure, air and water temperature), and oceanographic products. The APIs serve real-time and historical data from NOAA observation stations across the United States coastline and Great Lakes.
