A weather widget is a small application that displays current weather information on a device's home screen or website. It provides users with real-time updates on temperature, humidity, wind speed, and forecasts for upcoming days. Weather widgets can be customized to show specific locations and can vary in design and functionality. These widgets often pull data from reliable sources like weather services or meteorological organizations to ensure accuracy. They are popular on smartphones, tablets, and computers, making it easy for users to stay informed about changing weather conditions without needing to open a full weather app or website.
