Weather in September

September's average heat index is computed to be a tropical 30°C (86°F). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. 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 'apparent temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
