**Heat Index**

The heat index is the combination of the temperature and the relative humidity. When combing these two the result is how hot the air feels.

Following is a table which can be used to calculate the heat index. ---------------------------------------------------------------------------------------------------------------------------------------------------------

**How To Use the Table**

Locate the air temperature on the right side of the table then locate the relative humidity across the top. Where these meet on the table is the temperature of how the air really feels.....EXAMPLE:

1. Locate the temperature of 90° on the right.
2. Next find the relative of 80% across the top.
3. Where these two meet on the table is 113°. This is how the air feels. --------------------------------------------------------------------------------------------------------------------------------

The values on the table are used for readings taken in the shade with light wind.

When the readings are taken in the sunlight the values of the heat index may be as high as up to 15% greater than in the shade.

Exposure to strong winds, with very hot dry air can be extremely dangerous.
