The National Weather Service API (api.weather.gov) offers real-time forecasts, active alerts, radar data, and observations across the continental United States and territories. NOAA also publishes the Climate Data Online (CDO) API for access to historical climate and weather datasets, the CO-OPS Tides and Currents API for water level and oceanographic data, and the Aviation Weather API for aeronautical weather products. All NOAA APIs are free to use as open government data with no licensing restrictions.
NOAA publishes 15 APIs on the APIs.io network, including Alerts API, Aviation API, Glossary API, and 12 more. Tagged areas include Weather, Climate, Forecast, Alerts, and Ocean.
The NOAA catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
NOAA’s developer surface includes authentication, documentation, engineering blog, pricing, code examples, and 13 more developer resources.
