Challenge 2025
Following the success of last year’s OpenWeather Challenge, we’re excited to launch a new edition for 2025, more ambitious and even more impactful.
The OpenWeather Challenge 2025 invites you to develop data-driven projects using weather and environmental data. Whether you're creating an app, conducting research, or building tools to address climate or health challenges, this is your chance to make a real-world impact.
From air quality modelling to AI-powered forecasting and resilient infrastructure design, your project can help shape a more resilient and informed future.
