#noaa

Live marine weather and ocean conditions from NOAA's National Data Buoy Center (NDBC). The station catalogue (1,930 moored buoys and coastal stations worldwide) is searchable by name, type or coordinate; the live endpoint returns the latest observation for any station: significant wave height, wave period and direction, water and air temperature, wind speed/gust/direction, atmospheric pressure and more. Find the nearest buoys to any lat/lon. Ideal for surfing & sailing apps, marine operations, coastal monitoring and oceanography.

Live solar and geomagnetic conditions as an API, relayed from NOAA's Space Weather Prediction Center (SWPC). Get the current planetary K-index with its activity level and geomagnetic-storm scale (Kp 5+ → G1-G5); the real-time solar wind from the L1 point (speed, density, temperature, magnetic field Bz/Bt); the current NOAA scales for radio blackouts (R), solar-radiation storms (S) and geomagnetic storms (G); and the latest space-weather alerts, watches and warnings. Ideal for aurora forecasting, satellite & power-grid operations, HF-radio and amateur-radio apps, and science dashboards.

Live aviation weather for any airport as an API, relayed from NOAA's Aviation Weather Center. Get the current METAR observation for an ICAO station (e.g. KJFK → New York JFK: temperature, dewpoint, wind, visibility, altimeter, cloud layers, flight category VFR/MVFR/IFR/LIFR and the raw report) or the TAF terminal aerodrome forecast. Query one station or up to 10 at once (KJFK,EGLL,EDDF). Both decoded fields and the raw text are returned. Ideal for flight-planning tools, aviation dashboards, drone/UAV operations and weather apps.

High and low tide predictions for thousands of US coastal stations, powered by NOAA CO-OPS. Search the station directory by state or name, pull full station metadata (coordinates and time zone), and get tide predictions as high/low events or an hourly height series for up to seven days, in feet or metres and against the datum of your choice (MLLW, MSL, MHHW and more). Delivered through a fast, reliable API with clear errors for invalid stations. Ideal for boating and sailing, fishing and surfing, ports and logistics, beach and tourism services and coastal planning.
