Tomorrow.io vs OpenWeatherMap – Which API is Right for Your Business?

Weather forecasting technology has become increasingly important due to its direct impact on our daily lives. Accurate weather forecasting can make a difference between a good or a bad day, and this importance is not limited to individuals planning their outdoor activities. Businesses and industries, including logistics, aviation, construction, mining, and more rely heavily on weather data to predict and prepare for weather-related events that can result in significant financial losses.

For this reason, many companies consider weather forecasting a crucial component of their operations and use weather data APIs to access real-time weather data. This article will compare two popular weather APIs: Tomorrow.io and OpenWeatherMap, to determine the best fit for your business.

Why do you need a Weather API?

As a developer, you need a Weather API to access and integrate real-time, historical, and forecasted weather data into your applications. This includes temperature, pressure, humidity levels, wind speed and direction, UV index, and more. You can find free and paid options that offer different levels of access and varying calls per day. Two popular Weather API providers are Tomorrow.io and OpenWeatherMap.

Tomorrow.io vs OpenWeatherMap: Features

Tomorrow.io’s Weather API offers a comprehensive all-in-one endpoint that gives developers access to weather data via 80 fields, including weather, air quality, pollen, road risk, and fire index. It offers historical weather, real-time current weather, and forecast weather data globally backed by hyperlocal weather data. Tomorrow.io’s lean and flat payload offers a seamless developer experience with comprehensive documentation, cutting-edge functionality, and machine learning-backed features.

In contrast, OpenWeatherMap collects weather data from meteorological broadcast services worldwide and a network of weather stations. While it offers a feature-limited free option to access the 5 days/3 hour forecast API, weather alerts, and a weather map, its premium plans are more expensive than Tomorrow.io’s.

Tomorrow.io vs OpenWeatherMap: Compatibility

Tomorrow.io’s Weather API supports REST Weather API using JSON for the requests and the responses, with HTTPS support and is compatible with AWS, Autodesk, and other apps. It also provides developers with additional features like polygon/polyline locations, monitoring and alerts, and dynamic routes, allowing them to choose the right bounding box to continuously observe inclement weather within that specific lat/long vicinity.  OpenWeatherMap is compatible with JSON/XML and is suitable for app integration.
