Throughout September, the heat index is appraised at a hot 89.6°F (32°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children.

Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
