Weather in September
Temperature
Milan marks the start of September with an average high-temperature of a warm 85.1°F (29.5°C), hinting at a slight fluctuation from August's 89.8°F (32.1°C). Milan experiences an average low-temperature of 68.2°F (20.1°C) in month of September.Heat index
In September, the heat index is estimated at a sweltering 95°F (35°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
