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
Returns structured sea state data including significant wave height, dominant wave period, swell direction and height, a Douglas sea scale categorical verdict (e.g. 'Rough', 'Moderate'), and a boolean navigability flag indicating whether conditions are safe for vessel transit. Data is sourced from ECMWF and NOAA WaveWatch III models via open-meteo Marine.
Example use cases
Shipping disruption risk assessment
“Check the wave conditions and navigability flag at the Suez Canal chokepoint right now — I need the Douglas scale verdict and wave height so I can assess shipping disruption risk for my freight positions.”
Cargo route planning by sea state
“I'm routing a bulk carrier through the Strait of Malacca this week — can you pull the marine wave forecast including wave period, swell, and whether conditions are navigable?”
Multi-chokepoint maritime monitoring
“Give me the current sea state and navigability flags for Gibraltar and Bab el-Mandeb — I want to compare wave heights and Douglas scale ratings for both chokepoints.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/marine-wave-forecastWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.005 USDC) marine wave forecast with a pre-packaged Douglas scale verdict and navigability flag for key global chokepoints or arbitrary coastal locations — especially when combining with shipping disruption market signals or freight routing logic. Prefer over raw open-meteo Marine API calls when you need the chokepoint presets, Douglas classification, and navigability flag without custom parsing.
Side effects
- Unrecognized location string that is neither a preset chokepoint name nor parseable coordinates returns an error
- Locations far inland or with no marine coverage return empty or invalid results
- Model data may have latency gaps during ECMWF/NOAA update cycles
- Forecast accuracy degrades beyond 7-10 day horizon
- Ambiguous port names without coordinates may resolve incorrectly
