Weather in September
Temperature
The advent of September brings a subtle shift in temperature, with the average high moving from 92.5°F (33.6°C) in August to a still tropical 86.4°F (30.2°C). During the nights in September, Dotson experiences a consistent average temperature of 64.9°F (18.3°C).Heat index
The heat index value for September is computed to be a torrid 96.8°F (36°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. 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 are extremely vital to 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. 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. Experience reduced UV exposure by about half when donning a wide-brim hat. Take note! UV radiation from the Sun can double in intensity due to snow reflection.
