September weather forecast and climate
China, AL

September, the first month of the autumn, in China, is still a hot month, with average temperature ranging between max 87.4°F (30.8°C) and min 68°F (20°C).

Temperature

In September, the average high-temperature is almost the same as in August - a still hot 87.4°F (30.8°C). In China, the average low-temperature is 68°F (20°C).

Heat index

In September, the average heat index is evaluated at a torrid 101.5°F (38.6°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature', 'real feel', 'felt air temperature', or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (differences in body mass, height, and shape, metabolic differences, clothing). Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

The average relative humidity in September is 75%.

Rainfall

In China, during September, the rain falls for 16.6 days and regularly aggregates up to 2.72" (69mm) of precipitation. Throughout the year, in China, there are 176.5 rainfall days, and 37.72" (958mm) of precipitation is accumulated.

Snowfall

April through November are months without snowfall.

Daylight

In September, the average length of the day in China is 12.3h.

Sunshine

The average sunshine in September is 8.8h.

UV index

The average daily maximum UV index is 6. A UV Index estimate of 6 to 7 represents a high health risk from the exposure to the Sun's UV rays for the average person.
Note: The daily maximum UV index of 6 in September interpret into the following advice:
Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
