, the first month of the autumn, in Wuhan
, is also a moderately hot month, with temperature in the range of an average high of 27.9°C (82.2°F) and an average low of 19.9°C (67.8°F).
In Wuhan, the average high-temperature marginally drops, from a tropical 32.5°C (90.5°F) in August
, to a moderately hot 27.9°C (82.2°F). The average low-temperature, in Wuhan, is 19.9°C (67.8°F).
In September, the average heat index is calculated to be a hot 31.6°C (88.9°F). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.
Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'real feel', 'apparent temperature', 'felt air temperature', or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. This effect is subjective, depending on the activity and individual's heat perception influenced by various reasons (clothing, pregnancy, metabolic differences). 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.
The average relative humidity in September is 78%.
In Wuhan, it is raining for 9 days, with typically 79.7mm (3.14") of accumulated precipitation. Throughout the year, in Wuhan, China
, there are 124.7 rainfall days, and 1268.9mm (49.96") of precipitation is accumulated.
The average length of the day in Wuhan is 12.4h.
In September, the average sunshine in Wuhan is 5.9h.
In Wuhan, the average daily maximum UV index in September is 9. A UV Index estimate of 8 to 10 represents a very high health hazard from the exposure to the Sun's UV radiation for the average person.Note
: In September, the average maximum UV index of 9 translate into the following recommendations:
Take special precautions, as unprotected skin can be damaged and can burn quickly. 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. A wide-brim hat offers excellent sun protection for eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Tightly woven, loose-fitting clothes provide additional protection from the Sun. Protect yourself by liberally applying a sunscreen of at least 30 SPF. Sunscreen prevents sunburn and decreases the damaging effects of Sun's radiation on the immune system.
