Weather in September
Temperature
During the shift to September, Fountain Hill records a mild decrease in average high-temperature, moving from a hot 91.9°F (33.3°C) in August to a still tropical 86.4°F (30.2°C). September brings with it a nighttime average temperature of 67.1°F (19.5°C).Heat index
The heat index value during September is evaluated at a fiery hot 96.8°F (36°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Note that heat index values are valued for light wind and location in the shade. 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 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
