For September, the heat index is evaluated at a tropical 89.6°F (32°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees.

Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
