The temperature the body feels when heat and humidity are combined. The body dissipates heat by varying the rate and depth of blood circulation, by losing water through the skin and sweat glands, and as a last resort, by panting, when blood is heated above 98.6 F (37 C). Sweating cools the body through evaporation. However, high relative humidity r [..]

The Heat Index (HI) or the "Apparent Temperature" is an accurate measure of how hot it really feels when the Relative Humidity (RH) is added to the actual air temperature.

An index that combines air temperature and relative humidity to determine an apparent temperature-how hot it actually feels.

The heat index (HI) or “apparent temperature” is an approximation of how hot it “feels” for a given combination of air temperature and relative humidity (RH). Generally, higher RH values at the same t [..]

An index that combines air temperature and humidity to give an apparent temperature (how hot it feels).

T he perceived temperature to the human body based on both air temperature and the amount of moisture (humidity) present in the air. The body dissipates heat by varying the rate and depth of blood cir [..]

temperature that describes how hot it feels taking into account high air temperatures and high humidity levels.

Heat Index graphThe Heat Index (HI) or the "Apparent Temperature" is an accurate measure of how hot it really feels when the Relative Humidity (RH) is added to the actual air temperature. To find the Heat Index (HI), look at the Heat Index (HI) Chart (right). Heat Index graph As an example, if the air temperature is 90°F (found at [..]

The Heat Index (HI) or the "Apparent Temperature" is an accurate measure of how hot it really feels when the Relative Humidity (RH) is added to the actual air temperature.

An index that combines air temperature and relative humidity in an attempt to determine the human-perceived equivalent temperature

The apparent temperature of exposed skin when exposed to air with a high moisture content. Dry air allows evaporative cooling of the skin's surface. The higher the humidity, the less the skin can cool itself with evaporative cooling. Convergence

The combination of air temperature and humidity that gives a description of how the temperature feels. This is not the actual air temperature. Related term: Heat Index Chart.

This index is an accurate measure of how hot it feels (in degrees) when moisture (relative humidity) is added to the actual air temperature. Rain

The apparent temperature increase caused by the combination of high temperatures and high relative humidity. High humidity reduces the rate of evaporation of perspiration from the skin and thus reduces the cooling effect. This leads to the sensation of the temperature being higher than it actually is.

The temperature it feels like to people and animals. The heat index is a combination of temperature and humidity.

The temperature your body feels when the air temperature is combined with the relative humidity. As humidity increases, the rate of evaporation decreases. Our bodies are cooled by the evaporation of our perspiration. Therefore, if evaporation is slowed, the cooling of our bodies is slowed and we feel warmer.

The heating effect of any combination of temperature and humidity. Sometimes called the apparent temperature or comfort index.

This index is an accurate measure of how hot it feels (in degrees) when moisture (relative humidity) is added to the actual air temperature.

The combination of air temperature

The Heat Index is an index that combines air temperature and relative humidity in an attempt to determine the human-perceived equivalent temperature and how hot it feels. The result is also known as the "Apparent Temperature". For example, when the temperature is 32°C with very high humidity, the heat index can be about 41°C. The Heat Ind [..]
