NOAA Weather API

About NOAA Weather API

NOAA National Weather Service Weather API provides free, open access to authoritative weather data for the United States. The RESTful API delivers 7-day forecasts at 2.5km grid resolution, severe weather alerts, and current observations from thousands of stations. Data is available in JSON-LD format with cache-friendly responses. While lacking road-specific conditions or route optimization, it provides a solid baseline for logistics weather monitoring and is ideal for budget-conscious operations requiring basic weather intelligence.
