Weather in September
Temperature
Curbville marks the onset of September with an average high-temperature of a still tropical 87.1°F (30.6°C), a subtle shift from August's 91.4°F (33°C). In Curbville, the nighttime temperature averages to a comfortable 67.1°F (19.5°C) during September.Heat index
September's average heat index is estimated at a torrid 98.6°F (37°C). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a composite of temperature and humidity figures to convey how warm it feels. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
