More details

Get 7-day and hourly forecasts, latest station observations (METAR) and active NWS alerts for any US lat/long, or all active alerts by state. Official NOAA API.

Pull official U.S. weather data from NOAA's National Weather Service API (api.weather.gov) for any list of US coordinates:

• 7-day forecast (12-hour periods: temperature, wind, precipitation chance, humidity, short and detailed text)
• Hourly forecast (up to 156 hours)
• Current conditions from the nearest NWS observation station, including the raw METAR
• Active alerts (warnings, watches and advisories) for each point, or every active alert in a state as separate rows

Uses: logistics and field-service scheduling, construction and event planning, agriculture, insurance and claims triage, energy load forecasting, severe-weather alerting (schedule it hourly), and dashboards and AI agents that need reliable US weather without an API key.

Output

Location rows carry the NWS office and grid, nearest city/state, time zone, forecast zone, county zone, radar station, forecast[], hourlyForecast[], observation{}, activeAlerts[] and activeAlertCount. Alert rows carry the event, headline, severity, certainty, urgency, area, onset/expires and the description and instructions.

Notes

Coverage is the US and its territories only; points outside NWS coverage come back as found: false and are free. If no alerts are active in a state, you get one free informational row. Data is U.S. Government public-domain data from NOAA/NWS. Not affiliated with or endorsed by NOAA or NWS. Do not use this Actor as your sole source for life-safety decisions.

Pricing

Pay per event: weather-record at $0.0018 ($1.8 per 1,000). Charged per location forecast returned or per active alert returned. You pay only for results; not-found and error rows are free. Apify platform usage is included.
