Weather in September
Temperature
September's arrival coincides with a soft drop in the average high-temperature, subtly decreasing from August's torrid 96.4°F (35.8°C) to a hot 88.7°F (31.5°C). September nights cool down to an average low-temperature of 70.7°F (21.5°C).Heat index
The heat index for September is calculated to be a very hot 98.6°F (37°C). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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 body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
