Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees.
