The heat index for September is computed to be a hot 30°C (86°F). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Always consider that heat index estimations are for light winds and places in the shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, 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. Heat index values are particularly relevant to children. Kids are usually in more danger than grown-ups as they tend to sweat less.
