How this service works
SYNTHORA marine-wave-forecast: sea state for any coast/port or chokepoint (Hormuz, Suez, Panama, Malacca, Gibraltar, Bab el-Mandeb, Dover presets) — wave height, period, swell, Douglas-scale verdict and navigability flag. Complements chokepoint-transits for shipping disruption markets. Source: open-meteo Marine (ECMWF/NOAA WaveWatch III, no key). $0.005 USDC x402 Base.
Output
A JSON object containing current and hourly marine forecast data for the queried coordinate, including wave height, wave direction, wave period, swell height, wind wave height, and ocean current speed and direction, sourced from Open-Meteo's marine model.
Example use cases
Offshore shipping route risk scoring
“I'm routing a cargo vessel through coordinates 48.5°N, 5.2°W — can you pull the hourly wave height, swell period, and current data so I can score the sea-state risk for the next 24 hours?”
Surf spot swell check
“What's the swell height, wave period, and wave direction looking like at 21.27°N, 157.83°W right now and over the next few hours? I want to know if it's worth paddling out.”
Offshore wind farm sea state monitoring
“Pull the latest hourly wave height, wind wave, and ocean current forecast for our offshore platform at 55.8°N, 3.1°E — I need to assess whether conditions are safe for crew transfer today.”

Endpoint
POSThttps://marine-wave-forecast.hergertsynthora.com/service?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need marine-specific forecast data — wave, swell, and ocean current conditions — for a precise coastal or offshore coordinate. It is purpose-built for maritime, offshore energy, and surf use cases where sea-state data is required for route planning, risk scoring, or operational safety decisions, as opposed to general atmospheric weather APIs that lack wave and swell outputs.
Side effects
- Coordinates that are inland or non-coastal may return empty or invalid marine data
- Missing or malformed latitude/longitude values will result in a request error
- Open-Meteo marine model coverage may not extend to all ocean regions, potentially returning null data
- Payment failure via x402 protocol will block the response
- Extreme or out-of-range coordinate values may cause lookup failures
