Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees.
