Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still hot 87.6°F (30.9°C), closely aligned with August's 91.6°F (33.1°C). Hillman, in the month of September, anticipates a consistent average low-temperature of 69.6°F (20.9°C).Heat index
The heat index in September is evaluated at a fiery hot 102.2°F (39°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
