Note: The heat index, also known as 'real feel' or 'apparent temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees.
