Weather in September
Temperature
September signals a slight drop in average high-temperature, sliding from August's torrid 100.6°F (38.1°C) to a hot 93°F (33.9°C). During the month of September, an average low-temperature of 76.8°F (24.9°C) is recorded.Heat index
In September, the average heat index is appraised at an extremely hot 107.6°F (42°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
