Weather in September
Temperature
September implies a soft temperature shift, with average high-temperatures reducing from August's very hot 99.1°F (37.3°C) to a hot 92.8°F (33.8°C). In September, the average low-temperature is a warm 77.2°F (25.1°C).Heat index
The heat index value for September is calculated to be an extremely hot 109.4°F (43°C). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.When assessing, remember that heat index measurements are for light winds and shaded spots. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
