Introduction: Heat Index Calculator

The Heat Index Calculator helps you understand how hot it truly feels outside by combining air temperature and relative humidity. This “feels like” temperature is crucial for staying safe during hot weather, as high humidity can make it feel significantly warmer than the actual air temperature. Whether you’re planning outdoor activities, working in the sun, or monitoring weather conditions for health and safety, this tool provides an accurate heat index reading in seconds.
