Weather in September
Temperature
Ngassa marks the start of September with an average high-temperature of a still tropical 33°C (91.4°F), hinting at a slight fluctuation from August's 30.8°C (87.4°F). Ngassa cools down to an average low-temperature of 23.7°C (74.7°F) throughout the month of September.Heat index
The heat index in September is calculated to be a scorching 41°C (105.8°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Heat index specifics point out values are for conditions of shade and a slight breeze. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', comes about by integrating the temperature readings with the humidity levels. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
