Weather data & analytics · OpenWeather Ltd
OpenWeather
Widely used weather API offering current conditions, forecasts and historical data with a permanent free tier.
OpenWeather provides a set of REST APIs -- Current Weather, One Call, historical, air pollution and weather map tiles -- covering global locations, and is popular with developers largely because of its permanent free daily call allowance and simple integration. Paid tiers (Startup, Developer, Professional and Expert) scale API call volume and unlock features such as minute-level forecasts and bulk historical data. It is widely embedded in third-party apps, dashboards and IoT products where a lightweight, low-cost weather feed is enough, making it a common default choice ahead of more specialized or enterprise-oriented providers such as Meteomatics or Tomorrow.io.
