What is the heat index? - National Weather Service Figure 1 Heat index chart In order to determine the heat index using the chart above, you need to know the air temperature and the relative humidity For example, if the air temperature is 100°F and the relative humidity is 55%, the heat index will be 124°F When the relative humidity is low, the apparent temperature can actually be lower
WPC Heat Index Forecasts - Weather Prediction Center These heat index products are issued by WPC twice per day at approximately 02Z and 16Z for the valid days 3 through 7 They are based on an ensemble of model and human forecasts Deterministic plots indicate the most likely forecast while probabilistic plots depict the chance of exceeding various thresholds Plots are available for daily
Heat Index Calculator Heat index is often referred to as humiture, and is similar to wind chill in its attempt to measure the perceived rather than the actual temperature For example, an air temperature of 83°F with a relative humidity of 70% would result in an estimated 88°F perceived temperature This difference in perceived and actual temperature is the result
Heat index - Wikipedia The heat index (HI) is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade For example, when the temperature is 32 °C (90 °F) with 70% relative humidity, the heat index is 41 °C (106 °F
What Is the Heat Index, and Why Does It Matter? | Almanac. com 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°F, experts label it as dangerous heat The darkest grey area below indicates extreme danger Such temperatures carry a higher risk for heat stroke, exhaustion, and heat disorders
Heat Index - National Oceanic and Atmospheric Administration The Heat Index is based on work by R G Steadman and published in 1979 under the title "The Assessment of Sultriness, Parts 1 and 2 " In this work, Steadman constructed a table which uses relative humidity and dry bulb temperature to produce the "apparent temperature" or the temperature the body "feels"
Heat is getting worse in most places. See the heat index where you live The Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature To find the Heat Index temperature, look at the Heat Index Chart above As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index--how hot it feels--is 121°F
Heat Forecast Tools - National Weather Service The Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature To find the Heat Index temperature, look at the Heat Index Chart above or check our Heat Index Calculator As an example, if the air temperature is 96°F and the relative humidity is 65%, the heat index--how hot it feels
