TrayWeather is a free, open-source Windows utility that displays local weather conditions directly in the system tray. It shows the current temperature, weather icon, or both without requiring a separate browser window. Users can open a detailed weather dialog to review forecasts and other available meteorological information. The application supports OpenWeatherMap, Open-Meteo, and WeatherAPI as configurable data providers. Location settings can use automatic IP-based detection or manually entered geographic coordinates. Depending on the provider, additional information includes air pollution, UV indexes, weather alerts, and maps. Users can customize temperature units, update intervals, and visual settings. TrayWeather supports Windows 7 and newer, including portable installations.
