How to Create a Weather App in Power Apps

Power Apps enables developers to build custom business applications with minimal coding. By integrating external weather APIs, you can create a Weather App that displays real-time weather conditions, forecasts, temperature, humidity, and wind speed directly within a Canvas App.

Weather applications are excellent examples of API integration and can help users access location-based weather information without leaving the app.

Business Scenario

Suppose field engineers need weather information before visiting customer sites. A Weather App can provide real-time forecasts and weather alerts directly within Power Apps.
