Weather in September
Temperature
Richton's weather in September, with an average high-temperature of a still hot 87.8°F (31°C), subtly shifts from August's 91.8°F (33.2°C). Richton, in September, observes a steady average low-temperature of 68°F (20°C).Heat index
The heat index in September is appraised at a blistering 104°F (40°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the outcome of merging air's temperature and its humidity metrics. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. To cut down UV radiation exposure by about half, sport a wide-brim hat.
