Why Weather Data Matters
From delivery apps to farming dashboards, reliable weather data has become a must-have feature in modern applications. Whether you're a developer, a startup founder, or a small business owner, a weather data API lets you access real-time and forecasted weather information without collecting it manually.
With just a few lines of code, developers can pull global weather data and enhance their services with relevant and location-specific information.
What Is a Weather Data API?
A weather data API is a RESTful web service that delivers weather-related information through HTTP requests. It typically returns structured responses in JSON or XML format, making it easy for developers to integrate the data into apps or websites.
Most weather data APIs support the following:
- Real-time weather conditions
- Hourly and daily forecasts
- Historical weather records
- Weather alerts and warnings
- Search by city, coordinates, or postal code
