Weather in September
Temperature
Shifting into September, Brinson records an average high-temperature of a still hot 86.9°F (30.5°C), presenting minor fluctuations compared to the previous month. An average low-temperature of 69.6°F (20.9°C) is recorded during the nights in September.Heat index
The heat index for September is computed to be a very hot 100.4°F (38°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
