In September, the heat index is estimated at a tropical 87.8°F (31°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.One should consider that heat index numbers are for shaded settings and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
