Weather in September
Temperature
Arcola measures an average high-temperature of a still hot 87.4°F (30.8°C) in September, nearly consistent with the preceding month. During the month of September, Arcola anticipates a mean low-temperature of 72.9°F (22.7°C).Heat index
The heat index value for September is calculated to be a very hot 102.2°F (39°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Note that heat index values are valued for light wind and location in the shade. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
