How this service works
Upcoming high and low tides at a NOAA tide station: UTC and local times, heights in feet above MLLW, next tide and tidal range.
Output
Returns a JSON object with the station ID, name, state, time zone, datum (MLLW), and an array of upcoming tide events each containing type (High/Low), UTC time, local time, and height in feet. Also includes tidal range, next tide summary, data source URL, degraded-data flag, and any disclaimer or reasons for data quality issues.
Example use cases
Boater planning departure window
“I'm taking my boat out of Annapolis harbor — can you pull the tide predictions for NOAA station 8575512 for the next 2 days so I know when the tide is high enough to clear the shallows?”
Coastal photographer scouting low tide
“I want to photograph the tidal flats at low tide near San Francisco. Can you get me the next 3 days of tide predictions for NOAA station 9414290, including the exact local times and heights?”
Beach event safety planning
“We're running a beach cleanup at The Battery NY this weekend. Can you show me the tide schedule for NOAA station 8518750 over the next 3 days so we can avoid working during high tide?”

Endpoint
GEThttps://marine-conditions.x402tookit.com/tide-predictions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, multi-day tide prediction tables (highs and lows with times and heights) for a specific NOAA CO-OPS tide station. It is ideal when you already know the 7-digit station ID or have resolved it via the nearby-stations endpoint. Prefer this over generic weather APIs when tidal precision (MLLW datum, local vs UTC times, tidal range) is required for navigation, event planning, or marine safety.
Side effects
- Invalid or non-existent station ID returns an error or null results
- Station does not support tide predictions (e.g. water-level-only stations)
- NOAA CO-OPS upstream service unavailable causing degraded or empty response
- Days parameter out of range (must be 1–7) may return an error
- Network timeout from upstream NOAA data source
