Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

The average relative humidity in September is 79%.
