Weather in September
Temperature
The onset of September brings a small shift in high-temperatures, falling from a tropical 87.3°F (30.7°C) in August to a warm 81.1°F (27.3°C). In Joyceville, September is marked by an average low-temperature of 62.8°F (17.1°C).Heat index
September's average heat index is computed to be a hot 86°F (30°C). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
