Weather in September
Temperature
The arrival of September correlates with a minor temperature reduction, down from August's tropical 92.8°F (33.8°C) to a still hot 87.1°F (30.6°C). In September, Hampton encounters an average low-temperature of 65.8°F (18.8°C) during the night.Heat index
In September, the heat index is evaluated at a torrid 98.6°F (37°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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 process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
