Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still tropical 86°F (30°C), closely aligned with August's 90.1°F (32.3°C). In Waverly, September nights cool down to an average of 66.7°F (19.3°C).Heat index
September's heat index is appraised at a torrid 96.8°F (36°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.Understanding the heat index involves considering values for shaded locales with light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
