Weather in September
Temperature
The transition from August to September brings an average high-temperature of a warm 85.3°F (29.6°C), barely different from August's 90.5°F (32.5°C). Okolona's nighttime temperature during September is consistently averaged at an enjoyable 65.3°F (18.5°C).Heat index
September's average heat index is estimated at a sweltering 95°F (35°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Thinking about the heat index, one should account for its values in shaded areas 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 'feels like' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
