Weather in September
Temperature
With September's arrival, Quảng Luận notes an average high-temperature of a still hot 30.9°C (87.6°F), closely following the trend of the preceding month. During the month of September, the temperature falls to an average of 25.4°C (77.7°F).Heat index
In September, the heat index is computed to be an extremely hot 40°C (104°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. 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. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

The months with the highest UV index are May through September, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for the ordinary person.Note: A maximum high UV index of 7 in September translates into the following recommendations:
Take precautions against overexposure. Protection against sun damage is needed. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Arm yourself against UV rays' harm with protective apparel and UV-filtering shades. Be prepared! The intensity of the Sun's UV radiation can be amplified nearly double due to snow reflection.
