Frequently Asked Questions
The Buoy API aggregates wave buoy data from 10+ global networks including NOAA NDBC (USA & global), Candhis/CEREMA (France), puertos.es (Spain), hidrografico.pt (Portugal), Cefas Wavenet (UK), Mareografico (Italy), Sofar Ocean (global Spotter buoys), and Queensland Waves (Australia).
Update frequency varies by source, ranging from every 10 to 40 minutes for ocean buoys depending on the network. Our system continuously fetches the latest data from all sources.
The API provides wave height (significant and maximum), wave period, wave direction, swell data (height, period, direction), directional spread, water temperature, and wave energy — all sourced directly from ocean buoys.
Yes. The API provides full historical data access with date range filters and pagination. You can retrieve past readings for any buoy in the network, making it ideal for research, analytics, and machine learning applications.
The API supports multiple geographic query methods: bounding box search, nearest buoy lookup, and radius search. You can filter by coordinates, country, or data source to find exactly the buoys you need.
Yes. The /api/v2/conditions endpoint returns the nearest wave buoy reading for any coordinates. It automatically finds the closest active buoy and returns its latest wave data.
Yes. We provide full OpenAPI 3.0 documentation with an interactive Swagger UI for exploring all endpoints. The documentation includes detailed parameter descriptions, example requests, and response schemas.
Yes. Dedicated NDBC endpoints provide access to all US and global NOAA wave buoy stations with both realtime and historical data modes, including spectral wave data and oceanographic measurements.
The API is used to power surf apps, wave monitoring dashboards for harbors and coastal engineering, wave data widgets, oceanographic research platforms, IoT alerting devices, and wave modeling applications.
The API is currently in invite-only beta. Fill out the request form on this page to apply for early access. Once approved, you'll receive your API key and can start making requests immediately. The API uses standard REST conventions with JSON responses.
