Announcing the Harness the Weather Hackathon with


Postman and invite you to take on the challenge of innovating how we understand, interact with, and utilize weather data in this month’s Harness the Weather Hackathon, which is running now through August 1, 2023.’s high-precision Weather API provides real-time, forecast, and historical data for any location across the globe. But this is more than just a data repository; the API is loaded with the utility to drive specific use cases.

Your mission, should you choose to accept it, is to create a powerful backend application using the API that fundamentally transforms how weather data can solve real-world problems. We’re not looking for just any solution; we’re seeking applications that think outside the box, leveraging the intrinsic value and versatility of the Weather API.

You will be expected to deliver a Postman Collection complete with detailed recipes or code guides along with your application. Your project should demonstrate a robust understanding of the API’s capabilities and illustrate creative and practical uses of weather data that can potentially transform industries, communities, and the world.

Whether it’s optimizing supply chain logistics, improving disaster management strategies, enhancing agricultural practices, or delivering personalized lifestyle recommendations, the possibilities are endless. However, your solution should be more than just inventive—it should be applicable, scalable, and valuable.

So, are you ready to shape the future of weather data utilization? Time to put on your coding caps, tap into your inner innovator, and show us how you would “harness the weather.”

Remember, this isn’t just a code fest; it’s a creativity challenge. Show us the power of weather data through your transformative backend solution. Read all the details below—and then let the coding begin!
