Weather in September
Temperature
Livingston's transition into September involves a gentle shift in temperature, receding from a torrid 95.5°F (35.3°C) in August to a tropical 89.4°F (31.9°C). In September, Livingston encounters an average low-temperature of 69.3°F (20.7°C) during the night.Heat index
For most parts of September, the heat index is calculated to be a scorching 107.6°F (42°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
