Weather in September
Temperature
The onset of September notes an average high-temperature of a still hot 86°F (30°C), subtly shifted from August's 88.5°F (31.4°C). Anastasia records an average nighttime low of 75.9°F (24.4°C) in September.Heat index
The heat index for September is computed to be a sweltering 98.6°F (37°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Consider that heat index readings are for situations in the shade and light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
