How this service works
Observed tide water level from a NOAA CO-OPS station - latest level in metres and feet, rising or falling trend, and high and low over the window
Output
A JSON object containing the station ID, station name, latitude and longitude, the most recent observed water level (in metres and feet), the vertical datum used, the trend direction (rising or falling), the highest and lowest readings within the window, the number of 6-minute readings included, the window size in hours, the change in water level over the last 30 minutes, and a note providing context for interpreting the result.
Example use cases
Check tide before coastal kayak launch
“I'm heading out kayaking near The Battery in NYC — can you check the current tide level at NOAA station 8518750 and tell me if it's rising or falling and what the high and low have been in the last 6 hours?”
Monitor storm surge at harbor station
“Pull the observed water level for NOAA station 8723214 in Miami over the last 24 hours — I want to see the latest reading, trend, and how much the level has changed in the past 30 minutes.”
Tidal planning for marine construction crew
“What's the current tide height in metres at NOAA station 9410230 in Los Angeles, and what are the high and low values for the last 12 hours? We need to know if it's safe to work at the dock right now.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/tides/water-level?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time observed tidal water levels from a specific NOAA CO-OPS monitoring station along US coasts, rivers, or harbors. It is ideal for maritime planning, coastal safety checks, storm surge monitoring, and any application requiring current tide conditions with trend information. Prefer this over general weather APIs when tidal precision and NOAA gauge data are required.
Side effects
- Invalid or non-existent station ID returns an error or empty result
- Station temporarily offline or missing recent data may return incomplete readings
- Hours parameter out of range (not 1–48) may cause a bad request error
- NOAA CO-OPS API upstream outage may cause timeout or degraded data
- Station in non-US territory or non-CO-OPS network not supported
