Note: The heat index, also known as 'real feel' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees.
