Filter by state (2-letter code: TX, FL, CA), severity (Extreme, Severe, Moderate, Minor), urgency (Immediate, Expected, Future), or event type (Tornado Warning, Hurricane Warning, etc.). Get active weather alerts by US state or severity

). Use this to discover valid event type values for filtering alerts. List all NWS weather alert types available

Internally resolves the location to find active alerts in that area. Get active weather alerts for a specific US latitude/longitude

g., TXZ211, FLZ050). Zone IDs can be found via the get_point_metadata tool. Useful for focused monitoring of a specific area. Get active weather alerts for a specific NWS zone

Powered by real-time solar wind data. The gold standard for aurora forecasting worldwide. Get the aurora probability forecast map data (Ovation model)

Use ICAO codes (KJFK, EGLL, LFPG, SBGR). Get aviation weather station information by ICAO code

This is the statistical baseline that defines "normal" weather for any location. Get 30-year climate normals — the baseline for what is "normal" weather

Available at select CO-OPS stations with current meters. Get observed ocean current speed and direction at a US coastal station

This is the planet's largest archive of daily weather records. Filter by station, data types (TMAX, TMIN, PRCP, SNOW, SNWD), and date range. Stations are worldwide but densest coverage is in the US. Get daily weather data (GHCN-Daily): temperatures, precipitation, snow

Measures the intensity of the ring current around Earth. Values below -50 nT indicate a moderate storm, below -100 nT a strong storm, below -250 nT a severe storm. Critical for satellite operators and power grid monitoring. Get the Dst index — real-time geomagnetic storm intensity

Provide latitude and longitude for any US location. Returns high/low temps, wind speed/direction, precipitation probability, and detailed narrative. Get 7-day weather forecast for a US location by latitude and longitude

Use the 3-letter WFO code (e.g., OKX=New York, LAX=Los Angeles, MFL=Miami). Lists recent product IDs — retrieve the latest for full text. Get the Area Forecast Discussion (AFD) from a NWS Weather Forecast Office

Useful for programmatic analysis. US only. Get raw NWS grid weather data: temperature, precipitation, wind, humidity arrays

5 days. Includes temperature, wind, humidity, precipitation, and sky condition for each hour. US locations only. Get hour-by-hour weather forecast (156 hours) for a US location

Use this to plan for aurora viewing, satellite vulnerabilities, or HF radio propagation impacts. Get the 3-day Kp index forecast — predicted geomagnetic activity

Provide a 4-character station ID such as KJFK, KLAX, KORD, KDFW. Get current weather conditions from a specific NWS station

Provide ICAO codes comma-separated (KJFK, EGLL, LFPG). Returns temperature, wind, visibility, clouds, pressure, weather phenomena. Optionally retrieve past hours of data. Get METAR (current airport weather) for any airport worldwide by ICAO code

Complements water-level data for a complete coastal picture. Get coastal meteorological data: air temp, wind, pressure at a station

Monthly aggregates of temperature averages, precipitation totals, and degree days. Less granular than daily but ideal for climate trend analysis. Get monthly climate summary (GSOM): average temp, total precipitation, heating degree days

Useful for seeing temperature trends, wind changes, and weather evolution over recent hours. Get recent observation history for a NWS station

Filter by age (hours). Get PIREPs (Pilot Reports) for turbulence, icing, and weather conditions

Kp ranges 0-9. Values ≥5 indicate geomagnetic storms with visible aurora at lower latitudes. Updated every 3 hours. Essential for aurora hunters, satellite operators, and power grid managers. Get the NOAA Planetary K-index — geomagnetic activity and aurora probability

US locations only. Get NWS metadata for a US location: responsible WFO, grid coordinates, zones

List all NWS radar stations and their status

Shows long-term relative sea level trends calculated from decades of tide gauge data. Critical for climate research. Get long-term sea level rise trends for a US coastal station

These define areas of significant weather hazards for aviation: convection, turbulence, icing, IFR conditions, mountain obscuration. Get SIGMETs and AIRMETs — significant aviation weather hazards

7 solar flux index. Higher values (>100 SFU) indicate increased solar activity, more sunspots, and higher probability of solar flares and CMEs. Normal quiet-sun values are 70-80 SFU. Get the 10.7cm solar radio flux — a proxy for solar activity level

The solar wind drives geomagnetic storms — when speed exceeds 500 km/s with southward Bz, aurora probability increases dramatically. Get real-time solar wind speed and magnetic field conditions

Useful for understanding where a station is and what data it provides. Get metadata about a specific NWS weather station

Each station has a 4-character ID (e.g., KJFK, KLAX). US only. Use station IDs with get_latest_observation. Find nearby NWS weather observation stations by latitude/longitude

Includes forecast groups with wind, visibility, clouds, and weather changes. ICAO codes only. Get TAF (airport weather forecast) for any airport worldwide by ICAO code

Provides predicted high and low tide times and heights. Useful for fishing, boating, coastal activities. Default is next 48 hours. Get tide predictions (hi/lo) for a US coastal station

Data in meters relative to station datum. Provide a CO-OPS station ID (e.g., 8518750 for The Battery, NYC; 9414290 for San Francisco). Get observed water levels (tides) at a US coastal station
