aid: noaa-gov url: https://raw.githubusercontent.com/api-evangelist/noaa-gov/refs/heads/main/apis.yml name: NOAA — National Oceanic and Atmospheric Administration description: The National Oceanic and Atmospheric Administration (NOAA) is the United States scientific and regulatory agency within the Department of Commerce charged with monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, managing fishing and protection of marine mammals, and providing weather, climate, space weather, and ecosystem forecasts and warnings. NOAA's developer surface spans six line offices — the National Weather Service (NWS), the National Environmental Satellite, Data, and Information Service (NESDIS) including the National Centers for Environmental Information (NCEI), the National Ocean Service (NOS) including Tides & Currents (CO-OPS), the National Marine Fisheries Service (NMFS / NOAA Fisheries), the Office of Oceanic and Atmospheric Research (OAR), and the Office of Marine and Aviation Operations (OMAO). NOAA exposes free, open APIs at api.weather.gov, services.swpc.noaa.gov, api.tidesandcurrents.noaa.gov, ncei.noaa.gov/access, ERDDAP servers across line offices, the National Data Buoy Center (NDBC), and bulk forecast model output (GFS, GEFS, HRRR, GOES) through the NOAA Open Data Dissemination (NODD) program on AWS, GCP, and Azure. image: https://www.noaa.gov/themes/custom/noaa_components/logo.svg created: '2026-05-25' modified: '2026-05-25' specificationVersion: '0.19' tags: - Weather - Climate - Ocean - Space Weather - Government - Open Data - Forecast - Marine - Atmospheric - Hydrology - Satellite - Fisheries - Aviation - Emergency Management apis: - aid: noaa-gov:weather-gov-api name: National Weather Service API (api.weather.gov) description: The National Weather Service public REST API delivers real-time weather forecasts, alerts, observations, gridded forecast data, aviation weather products, and metadata for offices, zones, and radar stations across the United States and US territories.
