Weather in September
Temperature
September brings a slight decrease in temperature, down from a sweltering 100.6°F (38.1°C) in August to a hot 93°F (33.9°C). An average temperature of 77.2°F (25.1°C) is recorded during the nights in September.Heat index
September's heat index is estimated at a blistering 107.6°F (42°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
