For most parts of September, the heat index is estimated at a tropical 30°C (86°F). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
