2s.io Marine Weather Conditions
x402
2s.io Marine Weather Conditions is a paid API for AI agents from 2s.io, paid per call via x402, $0.0012/call, status unknown (last checked 2026-09-13).
Returns current marine/sea-state conditions (wave height, direction, period, swell, wind-wave) for a given ocean or coastal lat/lon coordinate

How this service works
Current marine/sea-state conditions for an ocean or coastal coordinate. Pass lat + lon. Returns significant wave height (m), wave direction + period, and the wind-wave and swell-wave components. Useful for surf, sailing, and coastal ops. Source: Open-Meteo marine (keyless). Returns 404 for inland points.
Output
Returns current marine sea-state data including significant wave height in meters, wave direction and period, and separate wind-wave and swell-wave components for the requested ocean or coastal coordinate. Returns 404 for inland points.
Example use cases
Example prompt
“What are the current wave conditions at 34.02°N, 118.95°W? I need the significant wave height, swell direction and period, and wind-wave breakdown.”
Technical details
Endpoint
GEThttps://2s.io/api/weather/marineWhen to prefer
Use this endpoint when you need real-time marine sea-state conditions — wave height, swell, and wind-wave data — for a specific ocean or coastal coordinate. Ideal for surf, sailing, or coastal operations use cases. Prefer over general weather APIs when marine-specific parameters (swell, wave period, wave direction) are needed. Note: returns 404 for inland points, so ensure coordinates are coastal or oceanic.
Side effects
- 404 returned for inland coordinates (non-ocean/coastal lat/lon)
- Missing or malformed lat/lon parameters returns an error
- Out-of-range coordinates may produce unexpected results
- Upstream Open-Meteo marine API unavailability causes failures
