Weather in September
Temperature
In September, Cannonburg experiences a barely noticeable shift in meteorological conditions, with average high-temperatures moving from 90.9°F (32.7°C) in August to a still tropical 87.3°F (30.7°C). In Cannonburg, an average nighttime temperature of 70.5°F (21.4°C) is expected during September.Heat index
The heat index for September is calculated to be a blistering 104°F (40°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
