Understanding Heat Index And Why It S So Important Woai The heat index was created to help better convey the dangers of excessive heat on the human body and relay how hot the current weather conditions are really making it feel to the average person. What is the heat index? the heat index is a measure of how hot it really feels outside, when humidity and other factors are considered along with the temperature, according to kimberly mcmahon, a.
Understanding Heat Index And Why It39s So Important Woai It’s fairly easy to follow. for instance, if the air temperature is 96°f and the relative humidity is 65%, the heat index—how hot it feels—is 121°f. the heat index assumes shady conditions with a light wind since it’s important to be in the shade during high heat. when the index measures anywhere from 103 to 125 degrees fahrenheit. The simplest definition of the heat index. the heat index roughly approximates how hot it “actually feels.”. this is different than the given temperature on the thermometer because the amount of humidity in the air affects how efficiently sweat evaporates from our skin and in turn keeps us cool. the more humidity there is, the less. The heat index is how hot it really feels when the relative humidity is factored in with the actual air temperature. when the heat index reaches 100 degrees or higher, it can be dangerous to be. In simplest terms, the heat index is the "feels like" temperature, or how hot it really feels when the relative humidity is factored in with the actual air temperature. your body cools itself by.
