The average heat index in September is computed to be a hot 30°C (86°F). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Note that heat index values are valued for light wind and location in the shade. 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 'real feel' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index.

Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
