Weather API for Developers

The Weather API provides real-time weather observations, alerts, map tiles, and other data at an affordable price.

About the API BETA

The weatherUSA Weather API is a simple-to-use REST/KVP interface for retrieving weather data primarily for locations across the United States, although current conditions are available worldwide. Some weather API providers only provide data every hour or less; our API provides real-time data for critical local information including mesonet (weather station) observations and severe weather alerts.

Real-time weather, historical weather, forecasts, and climate information are available via the API. The API accepts standard HTTP requests and returns standard HTTP response codes and JSON response messages for most endpoints. User management (for alerts & notifications), custom, and batch processing endpoints are also available by request.
