If the perspiration is not able to evaporate, the body cannot regulate its temperature. When the body gets too hot, it begins to perspire or sweat to cool itself off. This has important considerations for the human body's comfort. The heat index (also known as the apparent temperature) is what the temperature feels like to the human body when relative humidity is combined with the air temperature. For the most part the humidity is around 18%. Heat Index/Air Quality Forecast Heat Index In the month of May on average Phoenix gets 0.79mm of rain and approximately 0 rainy days in the month.
