OpenWeather

OpenWeather is a provider of weather data and APIs that enable developers, businesses, and researchers to access current conditions, forecasts, historical data, and weather-related imagery for integration into software and services. The platform is designed to support a range of use cases, from mobile apps to websites and Internet of Things devices.

The API suite includes Current Weather Data, 5 Day / 3 Hour Forecast, 16 Day Daily Forecast, Historical Weather Data, and Weather Maps that deliver tile layers for precipitation, clouds, wind, and more. Additional offerings may include weather alerts and other meteorological data services. API access is typically delivered via HTTP endpoints with responses in common formats such as JSON or XML, and results can be requested in metric or imperial units and multiple languages.

Access is controlled through API keys, with a free tier offering limited requests and paid plans providing higher quotas, priority support, and additional features. The platform emphasizes developer-friendly documentation, code samples, and SDKs to facilitate integration into various environments and applications.

Data sources are aggregated from a range of meteorological providers, including national weather services, weather stations, radar, and satellites. Because data collection methods and regional coverage vary, published weather information may exhibit differences in latency or precision across regions.

OpenWeather serves a global user base and is used to power weather-enabled applications, academic projects, and business workflows. The company positions itself as a developer-focused provider of accessible weather data and tools.
