Marine Wave & Tide Forecast (Open-Meteo + NOAA)
x402
Marine Wave & Tide Forecast (Open-Meteo + NOAA) is a paid API for AI agents from api.fadeandco.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).
Returns current wave height and period for any ocean coordinate via Open-Meteo Marine, plus next 24-hour high/low tide predictions for a specified NOAA tide station.

How this service works
Current wave height and period at a coordinate (Open-Meteo Marine), and, when a US NOAA tide station id is given, the next high and low tide predictions for the next 24 hours. Tide predictions exist only for NOAA stations; no wind or pressure forecast is included.
Output
A JSON object containing: current wave height in metres and period in seconds with a timestamp; tide predictions for the next 24 hours listing each event's time (GMT), type (high or low), and height in metres; the source coordinate; station ID if provided; and a note clarifying that NOAA tide data is astronomical only (no storm surge).
Example use cases
Surf session planning at Monterey
“What are the wave height and swell period right now at 36.625 latitude, -121.875 longitude, and when are the next high and low tides at NOAA station 9413450?”
Coastal kayaking tide window check
“I'm kayaking near Santa Cruz tomorrow — can you get the current wave conditions at 36.96, -122.02 and tell me the next high and low tide times from NOAA station 9413450?”
Offshore fishing departure timing
“Before we head out fishing at 34.0, -120.5, can you check the wave height and period there, and pull the next high and low tides from NOAA station 9410230 so we can plan our launch window?”
Technical details
Endpoint
GEThttps://api.fadeandco.workers.dev/api/agent-intel/marine-weather-tide-forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both real-time wave conditions (height and period) and astronomical tide predictions at a coastal US location in a single call. It is ideal for surf planning, boating, fishing, kayaking, or any coastal activity requiring ocean swell data combined with tide timing. Prefer it over generic weather APIs when marine-specific data (swell period, wave height, tide highs/lows) is the primary need. Note that wind and pressure are not included, and tide predictions require a US NOAA station ID.
Side effects
- Missing latitude or longitude returns a 4xx error — both are required
- Invalid or out-of-range coordinate values may produce no marine model data
- Non-existent or malformed NOAA station ID returns no tide predictions (waves still returned)
- Tide predictions only available for valid 7-digit NOAA station IDs; non-US locations have no tide data
- Open-Meteo API outage may result in no wave data returned
- Coordinates far inland or outside ocean model coverage may return empty or null wave values
