The first month of the autumn, September, is still a hot month in Wave, Arkansas, with temperature in the range of an average low of 66°F (18.9°C) and an average high of 86.9°F (30.5°C).

Temperature

The start of September comes with a small reduction in the average high-temperature, subtly receding from 92.8°F (33.8°C) in August to a still tropical 86.9°F (30.5°C). In the month of September, the nighttime temperature dips to a steady average of 66°F (18.9°C).

Heat index

In September, the heat index is calculated to be a sweltering 98.6°F (37°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
When referencing the heat index, its values are suitable for shady environments and light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
