Weather in September
Temperature
In September, the average high-temperature marginally drops from a fiery hot 97°F (36.1°C) in August to a hot 90.3°F (32.4°C). During September, the nighttime temperature averages to a warm 74.8°F (23.8°C).Heat index
In September, the heat index is evaluated at a blistering 105.8°F (41°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. As body temperatures escalate without effective heat release, one might face dehydration threats.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Notice this! Nearly double the intensity of the Sun's UV radiation can be caused by snow reflection.
