Weather in September
Temperature
The arrival of September is marked by a minor reduction in average high-temperature, sliding from a fiery hot 100°F (37.8°C) in August to a tropical 93°F (33.9°C). During September, Robberson's temperature falls to a steady low-temperature average of 77°F (25°C).Heat index
During September, the heat index is estimated at an extremely hot 109.4°F (43°C). Stay wary: Heat exhaustion and heat cramps are possible. Heatstroke can ensue from extended effort.Data suggests that the heat index is set for environments in shade and with a light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
