Weather in September
Temperature
In September, Nguyên Bình notes an average high-temperature of a moderately hot 28.8°C (83.8°F), hardly different from the preceding month. During the nights in September, Nguyên Bình experiences a consistent average temperature of 20.1°C (68.2°F).Heat index
Throughout September, the heat index is computed to be a very hot 35°C (95°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. 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 particularly relevant to children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
