Weather in September
Temperature
In Manchester, the beginning of September is marked by a marginally lowered average high-temperature, shifting from August's hot 88.3°F (31.3°C) to a moderately hot 81.1°F (27.3°C). Throughout the September nights, Manchester encounters a low-temperature of 61.2°F (16.2°C).Heat index
For most parts of September, the heat index is evaluated at 84.2°F (29°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
