Watermelons and summertime go together. Heat and summertime also go together. We, at the National Weather Service, as part of our mission for protecting life and property, have a measure of how the hot weather "feels" to the body, called the Heat Index. The Heat Index uses relative humidity and dry bulb temperature to produce the "apparent temperature" or the temperature the body "feels".
