Weather in September
Temperature
The onset of September brings an average high-temperature of a still hot 88°F (31.1°C), nearly matching the August temperature. The average temperature in Tunnel Springs during September nights dips to an agreeable 68°F (20°C).Heat index
In September, the average heat index is evaluated at a fiery hot 102.2°F (39°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Note that heat index values are valued for light wind and location in the shade. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
