Weather in September
Temperature
With the onset of September, Jessieville's average high-temperature slightly adjusts, moderately receding from August's hot 91.2°F (32.9°C) to a warm 84.6°F (29.2°C). In the month of September, the nighttime temperature dips to a steady average of 63.1°F (17.3°C).Heat index
The heat index for September is evaluated at a hot 93.2°F (34°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
