Weather in September
Temperature
The average high-temperature is a still hot 88°F (31.1°C) in September, hardly different from the 90.9°F (32.7°C) recorded in August. Kirkwood temperatures generally rest at a low of 72.3°F (22.4°C) during the September nights.Heat index
The heat index in September is calculated to be a blistering 105.8°F (41°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
