Temperature

The arrival of September sees an average high-temperature of a still warm 28.9°C (84°F), hardly diverging from August's 27.7°C (81.9°F). An average minimum temperature of 18.7°C (65.7°F) is recorded in Ban Nangeun during the month of September.

Heat index

The heat index in September is evaluated at a sweltering 36°C (96.8°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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 prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

UV index

February through June, September and October, with an average maximum UV index of 6, are months with the highest UV index in Ban Nangeun. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for ordinary individuals.
Note: In September, the maximum UV index of 6 suggests this advice:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. In the presence of strong sunlight, it's crucial to wear sunglasses that ward off UVA and UVB rays.
