Weather in September
Temperature
In September, China experiences a minor shift in meteorological conditions with average high-temperatures marked at a still hot 87.4°F (30.8°C), closely mirroring the climate in August. China reports an average low-temperature of 68°F (20°C) during the nights of September.Heat index
For September, the heat index is computed to be a torrid 102.2°F (39°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

The average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for average individuals.Note: The daily high UV index of 6 during September translates into the following recommendations:
Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
