Weather in September
Temperature
The shift into September uncovers an average high-temperature of a moderately hot 83.7°F (28.7°C), subtly different from the previous month. An average nighttime temperature of 67.1°F (19.5°C) is recorded in Hemingway during September.Heat index
During September, the heat index is evaluated at a hot 93.2°F (34°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
