Official US National Weather Service Weather Data API

Overview

The US Weather API (powered by the US National Weather Service) offers RESTful access to official weather data including 7-day forecasts, severe alerts, real-time observations, radar imagery, and climate data for U.S. locations. Key endpoints include /points (location grid coordinates), /forecast (daily/hourly forecasts), /alerts (weather warnings), and /observations (current conditions). Responses are in JSON format. Ideal for integrating into mobile apps, emergency systems, travel tools, or local news platforms to deliver accurate, government-sourced weather information.
